Accidental Kiss: In Royal Occupation, Tucker accidentally kissed a brainwashed Jazz when he tried to block her view. Fortunately, it helped to undo his froggy transformation. Also, as a Continuity Nod to the cartoon, Tucker mumbled about the one with Sam.

Amnesiac Lover:Danny and Sam end up like this when Nocturne traps them in a dream world where they have no memory of each other. However, they manage to fall back in love with each other even before they regain their memories.
And Then What?: In Strength In Numbers, Danny's enemies honestly hadn't come up with a plan for what to do if (and when) they finally caught him.
Danny: (sarcastically) Well, isn't this an amusing little development?
Arbitrary Skepticism: During her conversation with Desiree in What She Wants, Jazz finds it hard to believe that in life, Desiree discovered an Ifrit, even though she's talking to a ghost.

Attention Deficit... Ooh, Shiny!: In Pairing OffTechnus is in the process of telling Skulker that they just can't grab anything that gets their attention for their plan when something catches his eye. He even says the last two words of the trope.
Backstory: The series expands on Desiree's backstory and why she decided to twist the wishes she granted.
The series also gives one to the remains of Freakshow's circus trope that explains their life before Freakshow took control of them and what happened to them following the events of the episode "Control Freaks".
Badass Family: The Fentons, now more than ever now that they're all on the same page.
Badly Battered Babysitters: This happened to Tucker and the Fentons when Danny and Sam were reverted into five year olds. According to Jazz, this happened the first time when Danny was five, without ghost powers.
Bait and Switch: In Stolen Years, it at first looked like the Fenton Ghost Guzzler was going to successfully suck up energy of Jack's test subjects, only for it to instead suck up electrical power.
Baleful Polymorph: In Royal Occupationwhile everyone else (except for Danny and Sam) were brainwashed into Aragon's subjects, poor Tucker was transformed into a frog.

Batman Gambit: In his typical manner, Clockwork pulled one of these by bringing in Future Danny and Sam to recapture Dan, thus leading to Sam getting her ghost powers.
Before I Change My Mind: When Sam was about to go through with her plan to get her ghost powers, Jazz arrived and gave an argument against it. However, when Jazz saw that Sam was doing this mostly to help Danny, she turned her back and said the trope name.
Berserk Button: Too many to name. In fact, somebody manages to push someone else's button at least once every story.
Big Blackout: One of Jack's experiments resulted in this, much to the annoyance of Danny and the neighbors.
Then later, it helped the heroes when it was used to suck up all the power from the Guys In White's headquarters.
Big Brother Instinct: Danny to Danielle, even moreso than in the cartoon, especially since she is now Happily Adopted into the Fenton family, making her an actual little sister. This was shown big time in Stolen Years, where, after the Guys In White kidnapped Danielle, Danny tore through an entire group of them. Jazz finds that she likes seeing Danny going through this phase.
Big Damn Heroes: In Laws of Attraction, the Fentons, Tucker, Valerie, Wulf, and Elastica pull this when Danny and Sam are up against Walker and his forces.
And before that, Sam and Danielle led the denizens of the Far Frozen against the ghosts who captured Danny in Strength In Numbers.
Big Damn Kiss: Occurred in Hearts and Minds with Danny and Sam after they declared their love for each other.

Bond Villain Stupidity: Technus thought that he was being clever to distract Danny, Sam, and Tucker while he took control of the cybertron satellite again, but failed to keep an eye on his uplink which Valerie and Skulker sabotaged. As Tucker pointed out "If you wish to multi-task, you must learn how to split your focus".
Boring, but Practical: Sidney Poindexter's solution to Desiree's handicap of having to grant all wishes, even those of her opponents? Noise-cancelling headphones.
Breather Fic: Strength In Numbers, Pairing Off, and What She Wants.
Brick Joke: In What She Wants, Tucker mentions a phone app that has a profile on every ghost they know to Valerie. Later in the story, Jazz reveals she has it.
Call Back: In the cartoon, Danny once said he was a whiz at dodge ball. Being his clone, Danielle apparently is too. Though Word of God is that unlike Danny's skills which are instinctive, she honed her skills through her ghost battles.
The series also remembers that Valerie's new armor was created by Technus, which unfortunately enabled him to deactivate it to her confusion while he mockingly pointed out where she thought it came from.
Danny also made one to the time Spectra infected everyone with ghost mosquitoes when he and Sam fought a giant ghost bee.
In Pairing Off, when Tucker and Technus square off, Technus mentions the last time they fought in "Teacher of the Year", and the numerous defeats Tucker received.
Cannot Spit It Out: Danny and Sam initially had this problem when they confessed their true feelings for each other.
Can't Get Away with Nuthin' : In Junior Hijinks, Danielle learned the lesson Danny did about using her powers to get back at people she didn't like when she ends up dealing with the Masters' Blasters, followed by her having to deal with her parents.
Cassandra Truth: After his encounter with Sam at the end of the first story, Box Ghost told the other ghosts that she now had ghost powers, but they didn't believe him...at least until they saw it for themselves.
Casual Danger Dialog: In Pairing Off, Danny and Sam have a pleasant conversation while in the middle of battles with Technus and Skulker respectively.
Catchphrase Interruptus: When Danny and Sam were about to transform to deal with what they thought was a killer robot, they yelled out "We're going..." only to stop and yell "Tucker?!" when they realized who was controlling the robot.
Character Development: In addition to not derailing the development the characters have gone through in the cartoon, the series adds more to it, as well as providing some to new members of the main cast like Danielle as well as secondary characters like Desiree and Sidney Poindexter.
Chekhov's Gun: The Fenton Spectral Shrieker and Ghost Guzzler at first seemed like faulty experiments, but then they helped Danny and the others storm the Guys In White's headquarters.
Also, the pair of gloves that shocked Danny towards the beginning of the first story of the series played a big role in its climax.
The ectoranium that Jack and Maddie were experimenting with in Royal Occupation came in handy to help defeat Aragon at the climax.
Chest Insignia: Inverted. When Sam finally gets her own logo, it's on the back of her coat. Danny and Tucker point out the impracticalness of it being there, but Sam doesn't care.
Combination Attack: Danny and Sam have a tendency to combine their powers to deliver more damage to their opponents.
Complaining About Rescues They Don't Like: In Laws of Attraction, Paulina allowed herself to be captured by Walker's forces so that she could be rescued by Danny Phantom and hopefully, start a relationship with him. Naturally, she wasn't happy when Sam Tasma was the one to come.
Conflicting Loyalty: Danny went through a moment of this in Trial By Fire when it came to finding and helping a 'scared out of her mind' Sam who couldn't control her new fire powers or protecting the city from Undergrowth. Fortunately, the rest of Team Phantom encouraged him to go after Sam while they held down the fort.
Conqueror From The Future: Not so much a conqueror, but it was clear that Dark Danny intended to recreate the devastated world he came from in the present if not for the intervention of Future Danny and Sam.
Continuity Cavalcade: Hearts and Minds is full of these as amnesiac Danny and Sam had memory flashes dealing with their relationship every time they came into contact.
Continuity Nod: One of the things that makes the series good is that it follows continuity as much as the cartoon, mentioning things from the television show as well as events that take place within itself.
Crazy-Prepared: Tucker brought hacking equipment and tools on the mission to rescue Dani from the Guys in White on the off chance he got to use it on one of their main database hookups. He got to, deleting all files on Danny, Dani, and Sam.
Curb-Stomp Battle: Whereas Vlad Plasmius used to deliver these in the cartoon, he's now on the receiving end from a number of characters that are too many to count.
Curse Cut Short: Being very edgy for a fanfic based off a show on Nickelodeon, Future Danny started to say to Dark Danny "You son of a...", only for Dark Danny to stop him short and remind him who that insult would be directed at.
Curse Escape Clause: Being Genre Savvy to Aragon's penchant for everything Dark Age, Tucker believed that his frog curse could be broken by a kiss from a maiden. Turns out, he was right when he wound up accidentally kissing Jazz.
Desiree's wish-granting-compulsion was given to her by a genie during her life and can only be cured by meeting her one true love, and from then on she only has to grant his wishes. It's Sidney Poindexter.
Deep Sleep: This was Nocturne's ultimate plan for Danny and Sam in Hearts and Minds.
Defensive "What?": Jack said this when Danny looked at him after coming up with the idea to use his inventions to save Danielle from the Guys in White.
Digging Yourself Deeper: Subverted by Danny. Whenever he makes comments about other girls that makes Sam jealous, he follows up a nice recovery.
Easy Come, Easy Go: After an April Fool's joke ended up embarrassing him, Poindexter ended up as a Butt Monkey again at his ghost school. Fortunately, it gets better for him when he becomes the school's principal.
Empowered Badass Normal: Sam, who at first only fought ghosts using Fenton weapons, now has powers like Danny, making her just as dangerous to ghosts as him.
Enemy Mine: In Pairing Off, Ember temporarily worked with Danny and Sam in order to save her boyfriend Skulker.
Energy Absorption: In the first story of the series, Vlad modified a pair of gloves that were designed to hurt ghosts that touched them to absorb energy from them. Fortunately, Danny and Sam destroy them before the first story ended.
This was also the attempt of one of Jack's inventions. Unfortunately, it ended up absorbing electrical energy instead.
Engineered Heroics: According to the series' point of view, the Masters' Blasters capture of Aragon in "Phantom Planet" was part of a deal with Vlad in exchange for the return of his amulet.
Epic Fail: In Stolen Years, Jack attempted to build a device that emitted a sound that only ghosts could hear, but got it backwards and made it a sound that humans could hear but ghost couldn't. Then, he built a device to suck the power out of ghosts, but it ended up sucking electrical power.
Inverted later in the same story when the failed inventions helped Team Phantom's mission to save Danielle from the Guys In White.
Foreshadowing: In Pairing Off, during a battle between Danny and Technus, Technus says everyone could benefit from an upgrade. That is precisely what happens to Skulker after Technus upgrades his suit.
According to the author, it wasn't intentional.
Another moment in the same story occurs when Paulina feels jealous that Sam has a boyfriend while she's dateless. This culminates in Laws of Attraction where, after Danny and Sam are inadvertently named Casper High's hottest couple, she attempts to make Danny Phantom her boyfriend to overshadow them.
Another instant that's appearing throughout the series is ghosts noticing something special about Danny and Sam which seems to have something to do with their new link.
Forgot About His Powers: After making herself and Danny intangible to avoid a barrage of ghost rays, Sam finally lampshades on Danny always allowing things to hit him.
Fountain of Youth: In Stolen Years, a run-in with the Guys In White and an experimental weapon causes Danny and Sam to change into five year olds physically and mentally.
Gendered Outfit: Sam's ghost costume is actually one of the jumpsuits that Danny wore when he got his powers except with the neckline and boots replaced with a choker and army boots, most of the gloves cut away except the middle finger, the entire midriff cut away, and topped off with a coat with laced sleeves. Justified that Sam used one of Danny's suits because they're the same size, though at the same time, Sam gets sort of a guilty thrill about wearing something of her boyfriend's.
Genre Savvy: In Pairing Off, Danny and Sam weren't surprised that Skulker and Ember were about to attack them and quickly freeze them.
Jazz was also this when she used Desiree's wishing powers against her in What She Wants.
Nocturne also showed shades of this when targeted Danny and Sam before attempting another takeover of Amity Park.
Seeing that humans were intangible inside his prison, Walker constructed a wing of cells to hold humans. Unfortunately, he didn't know about Sam's new powers.
Get Out: Danny and Sam yelled this to Nocturne when they forced him out of their subconscious.
Girl Posse: Victoria, the rich snob at Elm Street Middle School has one consisting of two girls that Danielle simply refers to as Friend One and Friend Two.
Give Geeks a Chance: In one of the biggest shocks of the series, Desiree ending up together with Sidney Poindexter. Tucker even lampshades the trope and wonders why it can't happen to him.
Guinea Pig Family: While Jack won't tear Danny apart molecule by molecule now that he knows his secret, he doesn't mind having Danny assist him in testing out new ghost weapons, much to Maddie and Jazz's objection.
Gluttony Montage: Danny goes through one that lasts two hours in Strength In Numbers. Justified that he couldn't control himself as Desiree had cast a spell on the food that made him eat.
Heroic Will Power: Done twice in Trial By Fire. First was when Undergrowth attempted to seize control of Sam again, she accidentally released a gigantic surge of fire, then when he tried again she gained full control of her flame powers and broke free.
"Hey, You!" Haymaker: While fighting a giant ghost bee, Sam tapped on its thorax with a ghost construct hand before flicking it away after it turned around.
How Do I Shoot Web: When Sam initially got her ghost powers, she thought that it would be a snap considering she'd seen Danny do it hundreds of times, only to find out that she had the same trouble controlling them that he did at first. This carried over when she got her fire powers.
How the Mighty Have Fallen: Said word-for-word by Vlad to Aragon in Royal Occupation, though it's kind of the pot calling the kettle black when you think about it.
Hypocritical Humor: In the cartoon, Sam got on Danny for whenever he used his powers for his own purposes, but she didn't mind using her new powers for her causes, demonstrations, and protests, at least until Danny made her stop.
I Can't Hear You: In one scene of Laws of Attraction, two of Walker's guards were putting up with Paulina's constant racket.
First guard: "Unnh! That's it! I'm putting in a request to get this brat in suspended animation!"
Second guard: (With his hands over his ears) What?!
I Don't Want To Know: This is Danny and Tucker's reaction when Sam hints that the first time she overshadowed with Danny around was not the first time she did it.
When Tucker asked what wish Desiree twisted to create haunted garden gnomes, she replied with this trope.
I Hate Past Me: While he doesn't hate him, Future Danny doesn't like that present Danny doesn't think before acting.
If You Taunt Her, You Will Be Just Like Her: After Sam made a comment regarding the fact that she has a boyfriend while Paulina doesn't to irk her, Danny warns her that if she keeps that up, she could end up like Paulina, much to Sam's horror.
I'll Pretend I Didn't Hear That: When Sam leaves Danny to carry a heavy load of Fenton tech, Danny calls her a credit to the female gender, to which Sam responded with this trope.
According to Word of God, the reason Sam's main powers are different than Danny's is because the Fenton Portal she used to get her powers was a different version then the one that gave Danny his as it was rebuilt following the events of the Grand Finale of the cartoon. Also, the reason he chose to give her different powers was because he wanted to give Sam a different route in mastering her powers than Danny so it wouldn't be dull.
Immediate Self-Contradiction: After Jack tells the Masters' Blasters that ghost hunting isn't about shameless self promotion, he asks Maddie for a drink, to which she asks if he wants Fentonade or Fenton-Up.
Is It Always Like This?: After Jack's experiment in Stolen Years causes half the city to lose power, resulting in a huge mob forming on the Fentons' doorstep, we get this exchange:
Danielle: "Uh, is this something I'm going to be seeing a lot of?"
Jazz: (disapprovingly) "Trust me, you don't even know".
Kid Detective: Mike Harris, a boy at Elm Street Middle School fulfills this trope as he likes to investigate strange things going on at school. Unfortunately, he seems to be on the trail of Danielle's secret.
Kinda Busy Here: Before Sam got her ghost powers, Danny's ghost fighting duties continuously interrupted their dates. It seemed like the first clue as to what would happen to Sam.
Leave Him to Me: This is what Agent Alpha, the leader of the Guys In White, says after Danny leads an assault on their HQ.
Limited Wardrobe: Averted with Wulf. He gets a new outfit to replace his prison garbs in the form of one of Jack's old Hawaiian shirts courtesy of Danielle.
Literal Genie: When Jazz wishes that the computer she's using could run faster, Desiree gives it the body of a track star.
Lockdown: Whenever Jack and Maddie experiment with ectoranium that was left behind after the Disasteroid incident, Danny and Sam and Danielle find themselves quarantined in clear boxes, much to Danny's annoyance.
Love at First Sight: When Poindexter first saw Desiree, he thought she was the beautiful woman he'd ever seen. It led to him helping her with her wish-granting handicap and eventually, freed her from her curse.
Mobile Maze: During Danny's third visit to Walker's jail, he discovers the passageways change, making it difficult to find his way around it. It's only through the special link he and Sam have that they're able to find each other.
Moment Killer: There has been one or two times when Tucker ruined a romantic moment for Danny and Sam.
Jack accidentally did this by accidentally releasing a bunch of ghosts on the city while Danny and Sam were taking advantage of being in the dark.
Mundane Solution: In What She Wants, Jazz figures a quick way to beat Desiree during a fight with Danny and Sam: Make a wish that she couldn't attack them. It's Lampshaded when Jazz won't stop giving Danny grief about it.
My Future Self and Me: Two of these to be exact. When Dan Phantom escapes, Clockwork brings in Danny's actual future self and his partner, Sam, to capture him.
Mysterious Watcher: The series has introduced a mysterious, new character who calls himself "G". He is powerful enough to beat the Masters' Blasters and also seems to be league a mysterious organization who have ordered him to keep an eye on Danny..
Naming Conventions: To avoid the 'Inviso-Bill' incident that Danny went through, Sam decided to create her own super hero name. After trying and rejecting a few, she settled on the name Sam Tasma.
No Name Given: Averted. The series reveals the names of the Groovy Gang (Fran and Andy) and Extreme Ghost Breakers (Brenner and Sullivan), as well as the names of the other members of Freakshow's circus trope besides Lydia (Goliath, Elasitca, and Green Kid).
Noodle Incident: What happened during Danny's first two hour eating binge. Apparently Sam finds it funny now while Danny hasn't gotten over it.
There's also the incidents Sam caused with her ghost powers with one at the steakhouse involving a dancing side of meat and another involving the animals in the biology lab that was so bad that the janitor was afraid to clean the science section alone for weeks.
Sam also hints that she's been using her overshadow ability in the past without Danny knowing, but Danny and Tucker don't want the details.
Another hint that the Fentons are visited by angry mobs frequently is that Jack commented that their formations are getting faster.
Now You Tell Me: Maddie calls out to warn Danny about a pair of anti-ghost gauntlets after they shock him.
Origin Story: The first story of the series is one for Sam Tasma
Pair the Spares: The series has created a uniquely new pairing, that of Desiree and Sidney Poindexter. Definitely one of the most bizarre, if not tender, moments in the series.
Papa Wolf: Jack Fenton. He even admits it in Stolen Years. "But heroes or not, NO ONE messes with Jack Fenton's kids!"
The Paralyzer: Maddie's sleeper hold technique is shown further, to the point where Sam wants to know how to do it.
Playing with Fire: Among the many differences Sam's powers are to Danny's is that she has developed ghostly flame abilities in contrast to his ghostly ice.
Poor Communication Kills: Because Danny and Sam didn't tell their friends they merely pretended to be broken up, Tucker, Valerie, and Danielle thought that the ghosts were responsible and went on the warpath in the Ghost Zone. Still, it was Justified because the ghosts were spying on Danny and Sam.
Puppy Love:Even when their mental capacities are diminished in their child forms in Stolen Years, signs of Danny and Sam's relationship still shine through. Maddie and Jazz find it adorable. Jack and Tucker, not so much.
Relationship Sabotage: A group of Danny's enemies attempted to do this in Bad Breakup. However, this failed due to a combination of Danny and Sam trusting each other and their attempts not being thought out.
Relationship Upgrade: The series takes place following Danny and Sam getting together in the cartoon's Series Finale. The author has done a nice job portraying how their new relationship would go, especially with Sam becoming Danny's new ghost fighting partner.
Rivals Team Up: After learning Danny's secret, Valerie Gray has not only abandoned her hatred of Danny Phantom, but she has become a permanent ally to him as well as a member of Team Phantom. However, she still has a strong resentment against other ghosts.
Roll Out The Red Carpet: When Tucker made his first appearance in the series, he did so by having a long carpet come rolling through Danny's house when he opened the door.
Dan Phantom also made a joke about the trope when he met Future Danny and Sam.
Running Gag: In A Family Thing, Jack accidentally shot someone with the Fenton Foamer three times over the course of the story: first Tucker, then Jazz, and then Bradley Milton who was being overshadowed by Vlad. Near the end of the story, he almost shot Danielle, but was blocked by an umbrella courtesy of Jazz.
For a series wide gag, there's Tucker "milking" being the new mayor of Amity Park.
A small one, but a group of ghost hunters causing a city-wide blackout and facing a court date because of it. Sound familiar?
Sick and Wrong: A few times throughout the series. One example was when Danny and Sam were quite disturbed by the sight of Skulker and Ember cuddling. Another was when Tucker and Valerie were freaked out by seeing Danny and Sam kissing while Sam was dressed as Danny.
This was also the reaction of everyone when Dash appeared, wearing a female cheer-leading outfit.
Speak In Unison: Danny and Sam, moreso than in the cartoon. The author has even expanded on this by having it be the basis of a special link they have developed.
Word of God is that he did it because he felt that all the times Danny and Sam had a 'unison moment' was Butch's way of making up for shelving the link that they had in the original draft.
Stable Time Loop: The reason Sam got her ghost powers was because she was driven by the revelation was that her future self was half ghost.
Sticky Situation: One of SkulkTech's weapons is a blaster that shoots out balls of ecto adhesive that, as Danny discovered, is immune to intangibility. Fortunately, Danny's ice powers manage to work well on it.
There's also a scene in the first story where Jack attempts to blast Future Danny with a weapon called Ecto Bondo that ends up trapping him, Maddie, and Jazz is a sticky mess.
Storming the Castle: Team Phantom invades the Guys In White's headquarters in order to save Danielle.
Super Mode: In the first story of the series, Danny unlocked a form that gives him a major power boost whenever he goes through extreme duress. Unfortunately, this has shades of Deadly Upgrade as he not only begins to act more and more beastly the longer he's in the form, but the energy he generates builds up too fast and can cause his body to burn out.
His future self seems to have gotten control of it and from the looks of her future self, Sam will get one too.
Swirlie: According to Poindexter, in life, he got this as much as he got shoved in his locker, much to Danny and Sam's disgust. It allowed him to use the toilet as a second doorway into Casper High.
For that matter, Dash was about to give a poor kid one of these when Poindexter made his appearance.
Take a Third Option: When Dan Phantom met Future Danny and Sam, he gave them the option to 'kneel and live' or 'fight and die'. Future Sam suggested mixing and matching.
Tempting Fate: In Junior Hijinksbefore the climax dealing with Danielle and the Blasters, Tucker lamented that there was nothing to do. Sam kicked him for it.
That's Gotta Hurt: Jack makes these comments while he and the kids watch Maddie beat up a clone of Vlad.
The Bus Came Back: The series features the return of many characters that only made one appearance in the cartoon, Dark Danny the most prominent.
It's implied that it was this that allowed Danny and Sam to regain their memories of each other in Hearts and Minds.
"The Reason You Suck" Speech: Over the course of the series, the heroes have delivered epic speeches to the villains. Danny gives a spectacular one to Walker in Laws of Attraction on how he's willing to break his own rules, calling him the biggest hypocrite he's ever met. During her fight with Undergrowth, Sam gives one to him about him being Not So Different than the humans who harm the planet. Considering what he made her do in cartoon, it definitely counts as a Moment Of Awesome. Maddie also gives one to Vlad in A Family Thing about how he doesn't love, just wants. He just shrugs it off.
The Unmasqued World: Averted. While many fans believe that the ending of "Phantom Planet" hinted that Danny's Secret Identity was revealed to the whole world, the author believes that it was kept secret by those at the South Pole. Word of God believes they keep secret other things besides what a teenager does in his spare time.
Third Wheel: Valerie had concerns that Danny and Sam were treating Tucker like this, but Tucker reassured her that even though they were together, they were still his friends.
This Is Something He's Got to Do Himself: Subverted. Danny at first thought he was the only one who cold stop Undergrowth in Trial By Fire, which is Justified seeing as how he did so in the cartoon. However, he ends up getting help from the rest of Team Phantom to bring him down the second time around.
Took a Level in Badass: Sam, full spades. While she was already a Badass Normal in the cartoon, after obtaining ghost powers, she's even more effective. What's more, despite her having her powers for a shorter time than Danny, she's already become just as powerful, which is justified because unlike Danny, Sam had someone to train her, her future self.
Torches and Pitchforks: More like Lanterns and Flashlights, but the anger was definitely there when the neighbors surrounded FentonWorks after Jack caused a blackout.
Training Montage: Sam went through one when she first got her ghost powers. It went just about as well as when Danny trained to use his ice powers (in fact, it occurred in the same arena), but she came out of it pretty awesome.
Two Scenes, One Dialogue: In Laws Of Attraction, there's a scene that switches back and forth between Danny and Sam and Tucker and Danny's family with members of Freakshow's circus to explain what happened to them following the first encounter with Freakshow in the cartoon.
Villain Team-Up: Multiple times. First, a group of Danny's enemies teamed up to capture him in Strength In Numbers, then again in Bad Breakup to break up Danny and Sam, and most recently in Pairing Off Skulker and Technus joined forces to form SkulkTech.
Villainous Breakdown: After being thoroughly thrashed by Future Danny and Sam, Dan flew at Danny and Sam in a blind rage. In his weakened state, he couldn't stand up to a double punch from the duo.
Vomit Discretion Shot: When Danny hurled the excess food he ate, it was described as everyone present stopping what they were doing and watch in disgust while the sound of Danny retching echoed around them.
Wham Fic: A Family Thing, big time. Danny's family learns about the existence of Danielle, Danny's advanced form is shown to have been not just a one time thing, it's revealed that Danny and Sam have a special link to each other, and Danielle is adopted by the Fentons.
For that matter, the first story of the series can be considered this as it's the beginning of Sam's new life as Danny's new partner.
Danny:"So what do you say, Tuck? Got any connections at the Mayor's Office that might be able to fast-track a set of adoption papers?"
What Were You Thinking?: This is what Danny said to Sam after finding out that she got herself ghost powers. Unlike most cases, Sam justifies her actions.
You and What Army?: In Strength In Numbers, Desiree says to Sam that in order to beat her and the other ghosts holding Danny, she'd need an army. Cue Frostbite and the Far Frozeners being led by Danielle.
You Are Grounded: In Trial By Fire, after Danny froze Jack and Maddie to keep them out of the battle with Undergrowth, Jack yelled this to him even though Danny was no longer in the room. Fortunately, following all the action, he forgot about it and Danny asked Sam not to remind him.
This is hinted to have happened to Danielle at the end of Junior Hijinks.
