All the time; the Lannisters in particular are masters of it.
In both "The Wolf and the Lion" and "Fire and Blood," Varys and Littlefinger have scenes that exemplify this trope.
The dinner scene with Cersei, Joffrey, Margaery and Loras in "Valar Dohaeris."
Pass the Popcorn: Walder Frey continues to slurp his wine while watching his men massacre Robb and his followers during Edmure's wedding.
The Patriarch: All the major houses have one, of course, but Tywin Lannister wins the prize.
Lord Tywin: The house that puts family first will always defeat the house that puts the whims and wishes of its sons and daughters first.
Peaceful in Death: Despite the horrific manner in which King Renly was killed, his body looks remarkably at peace. The corpse is later dressed and positioned in a way to make him appear regal and dignified, and Margaery can't resist mentioning how handsome he was, with Littlefinger agreeing.
By "Lord Snow," it looks like Daenerys and Khal Drogo are pretty damn happy together.
Ned Stark and Catelyn Tully as well, though it did not start that way.
Phallic Weapon: In season 3, Joffrey fires his crossbow from the hip, and the camera angle clearly implies this trope. This is after he has lovingly shown and described it to his fiancée, and he has already shown that he gets turned on by violence and killing.
Playing Drunk: Tyrion plays up his drunkenness, making very self-deprecating jokes, to get away with having made a threatening statement to the king.
Plot Armor: Not only subverted but outright inverted. GRRM has said that the safer a character "should" be by the rules of normal storytelling, the more deliberately he sets out to do them in.
Plot Triggering Death: Jon Arryn's death is what causes Eddard Stark and his family to become tangled in the game of thrones.
Poke the Poodle: Tyrion's "confession" in the Eyrie describes a number of acts which, while not exactly innocent, are hardly the stuff villains are made of.
"Where do I begin, my lords and ladies? I am a vile man, I confess it. My crimes and sins are beyond counting. I have lied and cheated, gambled and whored. I’m not particularly good at violence, but I’m good at convincing others to do violence for me. You want specifics, I suppose. When I was seven, I saw a servant girl bathing in the river. I stole her robe, and she was forced to return to the castle naked and in tears. If I close my eyes...I can still see her tits bouncing. When I was ten, I stuffed my uncle’s boots with goat shit. When confronted with my crime, I blamed a squire. The poor boy was flogged, and I escaped justice. When I was twelve, I milked my eel into a pot of turtle stew. I flogged the one-eyed snake. I skinned my sausage. I made the bald man cry into the turtle stew, which I do believe my sister ate—at least, I hope she did. I once brought a jackass and a honeycomb into a brothel—"
Posthumous Character: Lyanna Stark, Joanna Lannister, Aegon I The Conqueror, Rhaegar Targaryen, "Mad" King Aerys Targaryen and Jon Arryn are among the characters mentioned frequently but already dead by the beginning of the series, though Arryn is seen briefly (lying in state) in the pilot episode.
P.O.V. Cam: There is a tracking shot in Winterfell from the perspective of Bran's wolf Summer, following Hodor to Bran's bedroom and jumping onto his bed, which then immediately switches to Bran's POV as he wakes up and looks into the wolf's eyes. He then goes on to describe his "wolf dreams" to Maester Luwin.
The Power of Love: Averted horribly when Daenerys tries to use this to bring Khal Drogo out of a coma. Of course, it doesn't work, which is on par with the theme of the series.
Praetorian Guard: The Kingsguard, a group of knights who protect the king and serve for life. Like their namesake, one of their members was reponsible for the death of the previous king.
Pragmatic Adaptation: The series contains large amounts of pragmatic adaptation largely due to the transition from a rotating third person limited POV series of novels (complete with inner monologues) to a televised ensemble piece. Some changes worked better than others.
In the books, much character development and exposition is delivered in the narration or characters' internal monologues. The show comes up with creative ways to deliver the information in dialogue. For example:
Littlefinger tells his backstory with Catelyn to some employees at his brothel while training them in their duties.
Tyrion tells the story of Tysha to Bronn and Shae during a drinking game.
Much of the dialogue of Davos Seaworth in the TV series does not appear in the books, since much of his character development in these is restricted to his inner thoughts.
The show excises flashbacks and prophecies entirely. Flashbacks would require the expense of hiring an entirely different cast, while prophecies are tricky to write and pay off in a satisfactory manner. Because of this, Daenerys' hallucinations focus on her own story, rather than long-dead characters or those that live on a different continent; Ned's memories of his sister's demise are replaced with other foreshadowing devices; while the mysterious masked Quaithe's role is altered from prophecy sounding board to a foil for Jorah Mormont. Arguably, this streamlines and improves the series greatly.
Tywin Lannister, Robb Stark, and Littlefinger were offpage for the vast majority of A Clash of Kings, but the writers of a television show could not afford to have these popular (and probably well paid) actors disappear for a whole season. So they were either moved into someone else's story (Tywin into Arya's), had the previously secondhand exploits shown first hand (Robb's campaign and courtship of his non-Frey wife), or apparently develop mysterious teleportation powers to cameo in mulitple stories (Littlefinger making deals with at least three factions of the War of the Five Kings).
Arya's story had an extensive road trip portion with multiple kidnappings, then a stay in Harrenhal where she interacts with a bunch of new characters and ends up facilitating a palace coup with even more new characters. To streamline her story, much of the road trip portion was cut out and instead of working for Weese and later Roose Bolton (who was moved to Robb's camp for character development), the palace coup was cut out, and she only served one master in Harrenhal—known character Tywin Lannister. These changes also changed the focus of her story from the suffering of the smallfolk during war to the cat and mouse game to hide her identity.
Jon and Dany's stories in Clash were very internally focused with almost no action until the respective last chapters. To make them more action packed, Jon gets separated from the group to spend more time interacting with his love interest and Dany has to deal with the kidnapping of her dragons and betrayal by one of her handmaidens.
Due to the POV structure of the book, we needed two shadowbaby assassins birthed by Melisandre in order to understand how they came to be and what they did: the one that kills Renly (which we see in action from Catelyn's point of view) and later the one that ultimately kills Cortnay Penrose (which we see birthed from Davos's point of view). In the show, we see the same shadowbaby being born (with Davos smuggling Melisandre somewhere close enough so that the assassin can kill Renly, which is seen from Catelyn and Brienne's point of view.
Related to the cutting of the second shadowbaby, Storm's End, Penrose, and the entire subplot surrounding Stannis wanting his bastard nephew's blood was cut. Stannis's family was also cut from Season 2. However, with the casting of his wife and daughter in season 3, it remains to be seen how much, if any of Stannis's family drama and Storm's End is repurposed for Season 3. Considering that Stannis does not do much except sulk in Book 3 until serving as the Big Damn Heroes for Jon at the Wall, moving the Storm's End and Stannis's family plot to Season 3 may be the most pragmatic way to adapt that storyline, especially since the third book is going to be spread out over two seasons.
In the books, all POV Stark children whose direwolves are still alive (meaning Jon Snow, Arya and Bran) are shown warging into them when sleeping. In the series, only Bran's dreams are kept, because they are essential to his Story Arc, while Jon's and Arya's stories can work without them.
In the books, Barristan Selmy joins Daenerys under the alias Arstan Whitebeard, which is enough to disguise his identity as Daenerys is the only viewpoint character for this story, and had never seen him before. On the show, of course, the actor is easily recognizable, so he reveals his true identity to her right away.
Loras is older than Margaery in the novels, but it was revealed by Bryan Cogman in this interview that Margaery is Mace Tyrell's eldest child on the show. The switch in birth order was no doubt due to the fact that Finn Jones is six years younger than Natalie Dormer, the actress who plays his character's sister.
Ser Loras Tyrell; George R.R. Martin even described the character as "...the teen idol of Westeros" in this HBO featurette. Sansa Stark has a crush on him because of his good looks. Two lowborn Lannister soldiers consider him to be prettier than the Queen. In "The Climb," Lady Olenna calls Loras "...the pride of Highgarden, the most desirable bachelor in all of the Seven Kingdoms."
Jon Snow is prettier than half of Craster's daughters, according to Craster himself.
Deconstructed with Margaery, who is an astute politician and manipulator, but puts on the persona of a charming and harmless princess to all and sundry. This has gained her the fanatical support of most of the common people.
And of course deconstructed with Sansa who was raised by her mother to be the perfect princess and is eager to fulfill this role, only to find her Prince Charming is a petulant evil psychopath ruling over a Crapsack World.
Daenerys seeks a mercenary army that she can use to invade Westeros. She goes to Astapor to purchase Unsullied, eunuch slaves who are considered the finest soldiers around.
Later, Daenerys meets up with the Second Sons, one of the many "Free Companies" utilized by the various cities and states of Essos.
Promotion to Opening Titles: Six recurring characters in Season 1, got promoted for Season 2: Jon Bradley (Samwell Tarly), James Cosmo (Jeor Mormont), Jerome Flynn (Bronn), Conleth Hill (Varys), Sibel Kekilli (Shae) and Charles Dance (Tywin Lannister). Oona Chaplin (Talisa Maegyr), Rose Leslie (Ygritte), and Joe Dempsie (Gendry) are promoted in season 3.
Properly Paranoid: The Wildlings insistence that you must burn dead bodies to prevent them coming back as wights under the control of the White Walkers.
The Dothraki, who will cut their hair in shame if they lose a fight.
And the ironborn take pride in the fact that they are reavers. They traditionally do not wear jewelry that was not won in battle. House Greyjoy's words, "We Do Not Sow," brag that they do not work for a living, they kill for it.
Psycho Supporter: Ramsay has two attractive women who seem to take pleasure in helping him torment Theon.
Bronn is pretty mellow when he's not fighting, but he makes it clear that he'll do anything for the right price.
Lannister soldiers are shown slaughtering the entire Stark household, even the septas, but when we see a few relaxing at camp, they're pretty normal people.
Puppet King: Cersei does her best to train Joffrey to become one of these for her. Subverted when Joffrey goes spectacularly off-script at the end of "Baelor," and his puppetmasters are powerless to stop him. Lampshaded by Tyrion in "The Pointy End":
Lord Tywin: Joffrey rules in King's Landing. Tyrion: My sister rules, you mean. (Tywin tilts his head in approval)
The Purge: In "The North Remembers", Joffrey has all of Robert's bastards hunted down and killed. It's rather disturbing to watch, considering many of the people involved are children.
The Dothraki are seen to be indulging in this, which comes back to bite Khal Drogo later on when he needs medical help.
Offscreen, by Ser Gregor Clegane at the behest of Tywin Lannister. Gregor Clegane's band is reported to be doing this in the Riverlands. Ned is so appalled that he officially attaints him and sentences him to death, giving the Lannisters yet another grievance against him.
However Tyrion successfully plays on this trope to motivate his reluctant soldiers during the Battle of Blackwater, saying they should fight not for honor, gold, glory, or their king, but to stop Stannis' army from sacking their city and raping their loved ones.
Rapunzel Hair: Common for a fantasy series, plenty of female characters sport this: Catelyn, Cersei, Talisa, Ros and several noblewoman and whore extras.
Red Baron: Sandor "The Hound" Clegane, Ser Gregor "The Mountain That Rides" Clegane, Ser Jaime "The Kingslayer" Lannisternote played with, as in-universe this is a mark of shame, Aerys "The Mad King" Targaryen, Daenerys "Mother of Dragons" Targaryen, Robb "The Young Wolf" Stark, Tyrion "The Imp" Lannister, Brynden "Blackfish" Tully, Qhorin "Halfhand", Oberyn "The Red Viper" Martell.
Reaction Shot: When Tyrion's plan to wipe out Stannis' fleet with wildfire goes ahead, the view switches between the carnage itself and the horrified expressions on onlookers' faces. Most notably, Sandor looks genuinely fearful, Tyrion looks remorseful, Joffrey almost smirks, and Pyromancer Hallyne is giggling.
Real Men Wear Pink: Loras' ornate armour, clothing and accessories always have a floral pattern. Justified, since his house's sigil is a rose, but he's still seen as being over-the-top about it, and is known as "the Knight of Flowers."
In "And Now His Watch Is Ended," Lord Commander Mormont manages to choke Rast after Rast (literally) stabs him in the back. While at first it appears that Mormont will take his killer to the grave with him, his wounds weaken him too much. Rast escapes and stabs Mormont some more.
Littlefinger tells an associate that he challenged Brandon Stark for Catelyn's hand because he'd heard all the stories and songs where the "plucky little hero" triumphs over the odds and wins the maiden's heart. However, Littlefinger wasn't a great swordsman or soldier, and Brandon was.
Theon Greyjoy attempts to behead Rodrik Cassel with an ordinary longsword rather than an Absurdly Sharp Blade of Valryian steel like Ned Stark uses. To make matters worse (perhaps on purpose), his victim only leans against the block with his arms rather than placing his neck against it.note The point of the block is to prevent Newton's First Law of Motion from pushing the neck away from the cut and thereby reducing its effectiveness. The result is as gory and horrifying as one can imagine.
Renly Baratheon tells Robert exactly what he thinks of his "glory days".
Renly: Which days exactly? The ones when half of Westeros fought the other half and millions died? Or before that, when the Mad King slaughtered women and babies because the voices in his head told him they deserved it? Or way before that, when dragons burnt whole cities to the ground?
Robert: Easy boy, you might be my brother but you're speaking to the king.
Renly: I suppose it was all rather heroic, if you were drunk enough and had some poor Riverlands whore to shove your prick inside and make the eight.
Lord Tywin's answer to Tyrion's demands:
Tywin: You are an ill-made, spiteful little creature full of envy, lust and low cunning. Men's laws give you the right to bear my name and display my colors, since I cannot prove that you are not mine. And to teach me humility, the gods have condemned me to watch you waddle about, wearing the proud lion that was my father's sigil, and his father's sigil before him. But neither gods nor men will ever compel me to turn Casterly Rock into your whorehouse.
Lord Karstark points out that Robb pardoned his mother for releasing an enemy, but wants to execute him for killing members of the same enemy family.
Jon: I know your people are brave, no one denies that. Six times in the last thousand years, a King-beyond-the-Wall has attacked the kingdoms. Six times they failed. You don't have the discipline. You don't have the training. Your army is no army. You don't know how to fight together.
Being assigned to the Wall is seen as this, especially since the majority of the guards stationed there are criminals who choose service over their punishments. Others such as Ser Alliser Thorne are members of the former regime who chose the Wall over death.
Cersei plans to do this to Ned Stark in "Baelor." Joffrey, however, has other plans.
Red Right Hand: Shade of the Evening stains the Warlocks' lips and mouths blue, making them easy to spot... when they are't hiding it with magic.
The Stark household guard, with the exception of Jory.
Lannister soldiers in a more literal sense.
Season one itself seems to be comprised of Stark bannermen and guards getting speared or destroyed. The only aversion to this is the Battle of the Whispering Wood, which in the series only shows the capture of Jaime. Of course, they were massively outnumbered before.
The Night's Watch, which is composed mostly of thieves and murderers who join to avoid their punishments. The rest of the kingdom forgets about them as they freeze and fight.
Robb's diversionary army is seen as completely expendable in-universe.
Refusal of the Call: Renly initially rejects Loras' suggestion that he should be king in "The Wolf and the Lion", but the idea gradually becomes more appealing after he argues with Robert, and he finally embraces it in "You Win or You Die." When Renly first appears in Season 2, he has already crowned himself king with the help of the Tyrells.
Lord Tywin: I see that the rumors of your demise were unfounded. Tyrion: Sorry to disappoint you, Father. No need to leap up and embrace me, I wouldn't want you to strain yourself.
Revealing Coverup: The attempted assassination of Bran was the only thing that gave Catelyn reason to believe that he hadn't fallen, but was rather thrown, causing her to dig deeper into the affair and discover various clues pointing to the Lannisters.
Revenge: Loras and Brienne swear vengeance against Stannis after Renly is murdered.
Revenge Before Reason: In "The Ghost of Harrenhal," Loras is ready to storm out of Renly's tent to put a sword through Stannis' righteous face, but Margaery and Littlefinger manage to convince him that it would be hopeless, as he would be killed by Stannis' men long before he ever reached his target.
Reverse Arm-Fold: Loras adopts this pose in Season 3 whenever he wishes to appear relaxed; examples include his greeting of Cersei and Joffrey in "Valar Dohaeris," while he walks away from Sansa in "Dark Wings, Dark Words," and Tyrion and Sansa's wedding ceremony.
Jaime and Cersei are seen having sex while wearing most of their clothing. Lampshaded by Benioff and Weiss in the commentary for the first episode, where they explain that Jaime is not only a master swordsman, but also a master of having sex without taking off any clothes.
Tyrion is also rarely seen naked during his sex scenes, as opposed to his partners.
Stannis Baratheon has sex with a completely naked Melisandre while covered in several layers of clothing.
Theon Greyjoy, of all people, gives a good one in "Valar Morghulis." It is immediately subverted, as one of his men gives him a Tap on the Head and announces they're going to flee. But he does concede that "it was a good speech"...
Royal Brat: Just look at the image on the trope's page.
Royally Screwed Up: The Targaryens provide the page quote for the trope, arguably due to a long-standing tradition of Brother-Sister Incest. And King Joffrey seems to combine the worst aspects of each of his already-unpleasant parents (also brother and sister).
In "Winter Is Coming," the Starks find two dead animals who died fighting each other—a stag and a direwolf. The latter has six pups which map directly onto the Stark children (including Jon Snow, who gets an albino who ran or was driven away from the others). Everyone is disturbed by this in-universe, as the symbolism of the house sigils is very important in Westeros. Theon Greyjoy is quick to suggest killing the pups, which serves as foreshadowing.
At the beginning of "You Win or You Die," Tywin Lannister is shown very calmly butchering a stag as he instructs Jaime on how to carry on the family legacy. (Apparently, Charles Dance was dressing a real dead deer.) A Deleted Scene of Season 3 has Tywin fishing. The sigil of House Tully is a fish.
In a room full of guards and soldiers, Littlefinger, a schemer with no physical talent, is the person who holds a knife to Lord Stark's throat, underscoring his backstabbing.
At the dinner table in "Valar Dohaeris," the Tyrell siblings are seated next to each other, while Cersei and Joffrey are positioned at the opposite ends. (To maintain symmetry, Margaery and Loras would normally have been placed across from each other.) Guess which family gets along harmoniously and which one is dysfunctional.
Ruling Couple: A ruling threesome in this case: King Renly, Queen Margaery and Ser Loras are presented as this in Season 2. Natalie Dormer describes their complicated union as a trinity in this featurette. It's Renly's romantic relationship with Loras which allows for the alliance to be created in the first place, and his marriage to Margaery seals the deal officially. Renly treats both his lover and his wife as his equals (the latter is shown symbolically in the melee scene, where Margaery's seat is of the same size as Renly's). The Tyrell siblings essentially function as a Brother-Sister Team in this three-way marriage; Loras' goal is to help Renly win the Iron Throne, while Margaery's job is to help her husband keep it.
Sacred Hospitality: Taken very seriously in Westeros. Once you've eaten bread and salt under someone's roof, you're their guest and are officially under their protection. It's illustrated in the story of the Rat Cook, told by Bran, who says violation of hospitality is the one crime that the gods cannot forgive. The law is flagrantly broken by Walder Frey at Edmure Tully's wedding to his daughter.
Sacrificial Lamb: The three members of the Night's Watch (Will, Gared, and Ser Waymar Royce) who appear in the pilot. And Lady. And Jory, squeaking in just under the 5-episode limit.
You're free to leave your cell in the Eyrie at any time; the cells actually have only three walls. Of course, the cells are cut into a cliff face, with the missing fourth wall being the one that would keep you safe from falling out into space. Lysa Arryn implies that the cells have sloped floors, which pull the prisoner closer to the edge, as Tyrion shows when he nearly rolls over the side in his sleep.
Joffrey gives a minstrel who offends him the choice between having his tongue cut out or losing his hands.
Sarcastic Clapping: Joffrey does this after hearing a minstrel's song mocking his family. The confused members of court aren't sure whether they should be joining him or not.
Screw the Money, I Have Rules!: Locke is a rare villainous example. He hates the fact that nobles can buy their way out of trouble, so he chooses to torture his noble captives rather than trade them in for riches.
A lot of the show's exposition takes place in brothels or during private visits in the early seasons. Why they divulge so many secrets and plot relevant info to their whores and one night stands is anyone's guess.
One episode has a scene where Littlefinger is training Ros and another new prostitute by having them go to town on each other, all the while talk about his plan to take over.
A Shared Suffering: The relationship between Cersei and Tyrion Lannister begins to resemble a brotherly one after Tywin reminds them both of the joy of living under his domineering thumb.
Sharp-Dressed Man: Whether he's at court, on a hunting trip, or commanding an army of about a hundred thousand men, Renly is always handsomely dressed for the occasion.
Jon Snow, Robb Stark, and Theon Greyjoy in season 1, as they're waiting for a shave from Winterfell's barber.
Renly and Loras have one in Season 1; Loras is shaving Renly's chest while trying to convince his lover that he should make a claim for the throne. They have another in Season 2 where they're kissing passionately in Renly's tent.
Joffrey in season 3, when he's trying out various royal outfits.
Loras has another in Season 3 when he beds Olyvar.
Shoot the Shaggy Dog: Ros' arc, a character who does not exist in book canon. For the majority of the first two seasons, she is a prostitute who exists primarily for the show's infamous "sexposition", although she has a distinct personality. At the end of season 2 and in season 3, she begins navigating the political world as a spy, and doing quite well for herself. She is killed in a brutal and sexualized manner in order to prove the cruelty of two (male) characters, both of whom have already had multiple scenes dedicated to just that.
Shrouded in Myth: Facts from the past are prone to be embellished or turned into legends. Aegon, for instance, didn't melt the thousand swords of his vanquished foes into the Iron Throne, but fewer than two hundred. This kind of mystique helps to seam the realm together.note George R.R. Martin's original vision of the Iron Throne is much larger and more monstrous-looking than the show version, with the "thousand swords" statement apparently being meant literally.
Sigil Spam: Many of the great houses have their emblem in everything. The Tullys have a pier outside Riverrun with fish carved to their beams. Sandor Clegane has a helmet the shape of a dog. Renly's crown has stag antlers on it. The Tyrells don't have a single article of clothing without their rose on it. The last one is pointed out by Lady Oleanna, as a reaction to the stitching of one of her relatives:
"Another golden rose. How original. I eat from plates stamped with roses. I sleep in sheets embroidered with roses. I have a golden rose painted on my chamber pot, as if that makes it smell any better. Roses are boring, dear."
Silent Credits: Used in "The Rains of Castamere" to allow the audience to absorb the shock of the brutal deaths of Talisa, Robb and Catelyn.
Sissy Villain: The eunuch Lord Varys subverts this trope brilliantly. Raised by actors, he knows how to play the role properly to keep the Queen and her council guessing. Even Magnificent Bastard Petyr Baelish doesn't quite know what he's up to. It's mostly an act, when he gets truly angry or serious he drops his usual polite, facetious tone and his voice becomes considerably lower, first seen when he delivers quite a hardass What the Hell, Hero? to Ned Stark.
Smug Snake: Cersei is one of these most days. Her father dresses her down for it.
Tywin : I don't distrust you because you are a woman, I distrust you because you're not as smart as you think you are.
Snake Oil Salesman: Bronn accuses Pyromancer Hallyne of being one of these, even going so far as to suggest that the Wildfire he's making is actually pigshit. Averted during the Battle of Blackwater, where his Wildfire turns out to be the real deal.
Ser Gregor kills his own horse and attempts to murder an unarmed Ser Loras (who only carried a shield at the time) after the latter defeats him in the joust.
Although Loras doesn't do or say anything negative to Brienne after she wins their melee competition, he's shown to be bitter about his defeat when he speaks to Renly in private.
The Spartan Way: The Unsullied are put through hellish training that makes them immune to pain and robotically loyal.
Speak Ill of the Dead: Cersei and Joffrey have no qualms posthumously calling Renly a "degenerate" in "Dark Wings, Dark Words."
Spikes of Villainy: Being made entirely of swords, the Iron Throne practically reeks of this trope. Aegon the Conqueror fashioned it to serve as a symbol and to intimidate the hell out of anyone who would challenge his rule, however, by all historical accounts, beyond that he was a surprisingly decent monarch. Played straight with Aerys II and Joffrey, who also adds giant spiky braziers to the bases of the pillars of the throne room.
Spirit Advisor: Jojen Reed has started to appear in Bran's dreams about the three-eyed crow, advising him on how to follow it.
Spoiled Brat: In "The Wolf and the Lion," Lord Renly reveals that his brothers consider him to be a spoiled child. Ser Loras' facial expression and his silence strongly indicate that he agrees. Renly then points out that Loras (whose family is richer than his) is overly-pampered as well.
Renly: And how much did your father pay for that armour of yours?
Spoiled Sweet: Although Renly grew up in the lap of luxury, he is genuinely a nice guy, and he does care about the smallfolk (at least more so than most Westerosi nobles).
Loras is a Type A in Season 3. He puts on a charming smile and a pleasant disposition most of the time, but his mask slips at a very public event in "Second Sons", and his misery betrays itself more subtly in "Valar Dohaeris" (Loras—who is no longer paying attention to the dinner conversation—has a melancholic expression when Joffrey says, "I'm sure she knows what she's doing"). In "The Climb", he sadly tells Sansa, "It's [King's Landing] terrible isn't it? The most terrible place there is," which clearly indicates that Loras is suffering in silence.
Stockholm Syndrome: Daenerys was basically raped the first few weeks or months of her marriage to a beast of a man whom she feared. However after awhile she embraces everything about his culture and comes to love and care for him and his people. Even when he threatens to murder, rape and pillage from the people who tried to assassinate her, she seems aroused. That's textbook Stockholm Syndrome.
Stock Scream: A faint but audible Wilhelm can be heard as soldiers of the Lannister army are patrolling the battlefield finishing off downed enemies in the final episode of Season 1.
Straight Edge Evil: Jaime Lannister discusses the trope in "The Bear and the Maiden Fair," commenting to the teetotal Roose Bolton, "You know how suspicious that seems to most people, don't you?" Bolton's not drinking is brought up again in "The Rains of Castamere", when his villainy is finally revealed.
Straight Gay: Renly Baratheon has a more masculine appearance and demeanour than his lover.
Loras is the sole male heir of the second-richest family in Westeros, and presumably he has duties in Highgarden and the Reach, yet in Season 2 he chooses to devote his entire life to protecting Renly. Being the Lord Commander of his brother-in-law's Kingsguard is a very convenient way for Loras to be able to spend a lot of time with his beloved, as his frequent visits can be explained away as being job-related. (It doesn't stop the rumours about them from spreading among Renly's followers, however.)
Almost the same can be said of Brienne, who is the sole surviving child of Lord Selwyn Tarth (and therefore his heiress), although in her case, she has to be content with loving Renly from a distance while she serves as his Kingsguard. What makes her dedication quite remarkable is that, as a woman, Brienne herself isn't obligated—or even expected—to physically fight for Renly when he summons his Stormlands bannermen (which Tarth is a part of) to his cause.
Succession Crisis: One begins at the end of episode seven, and is the main focus of season two.
Type 0: Most of the non-combatant cast, most peasants
Type 1: Ned Stark, Robb Stark, Theon Greyjoy, Jaime Lannister, Bronn, Stannis Baratheon, Ser Loras, Khal Drogo, Ser Jorah, Jon Snow, Yoren, Brienne of Tarth, Syrio Forel, Sandor Clegane, Ser Gregor Clegane
Loras' body language cannot disguise the utter disgust and frustration that he feels at having to bend the knee to Joffrey in "Valar Morghulis."
The abrupt and rude manner in which Loras storms away from the wedding feast in "Second Sons" is merely the tip of the iceberg in terms of the true depths of his anger over his current situation (i.e. his forced betrothal to Cersei, his inability to mourn for Renly in public, etc.).
Sure, Let's Go with That: Happens when Margaery explains to Sansa—who's dreading having to sleep with Tyrion when they're arranged to be married—how a woman might not know what she wants sexually until she's tried it.
Margaery: (smiles) Yes, sweet girl, my mother taught me.
Surprise Incest: Theon hits on a woman that met him at the docks, only to find out that she's his sister.
Suspiciously Apropos Music: Invoked. "The Rains of Castamere," a song about the slaughter of a major house that stood up against the Lannisters, is chosen as the signal to begin the Red Wedding specifically for its symbolic value.
Sword Pointing: In "The Ghost of Harrenhal," Loras points his sword right in Littlefinger's face and accuses the older man of wanting to sell him and his sister to Stannis as hostages.
