Damsel in Distress: Has a higher tendency to be shot, kidnapped and being thrown off a bridge than other characters, specially in season finales. But never as much as in Fan Fiction, where she fully drives the road to Chickification and becomes The Woobie for the single purpose of having Scotty save (and then have sex with) her.
Vigilante Execution: A major part of her character arc in the final season is whether or not she'd ever be willing to cross this line. She considers killing Moe Kitchener after he pulls a Karma Houdini in court but Kitchener's victim's father beats her to him. Then she has to talk down Diane Yates from doing this to Paul Shepard in "Bullet." In the Grand Finale, however, she finally decides to do it to her sister's abusive boyfriend... only for Scotty, who in the prior episode had become accessory in the death of a serial rapist, to tell her it isn't worth it.
Wide-Eyed Idealist: She really has a thing for pursuing old cases and bringing justice where everyone else considers it impossible, to the point of accepting to investigate cases that are 80 or 90 years old just because some distant descendant of the victim asks her to.
Gratuitous Spanish: Sort of subverted. He only "lapses" into this when talking to a character that knows Spanish and since the actor is bilingual he is perfectly capable to maintain a fluent conversation in the language.
Jerkass Ball: Usually alternated between him and Vera, although other squad members have been known to hold it on rare occasions.
Karma Houdini: More often than not. While many fans consider his Cowboy Cop antics "heroic" and "the right thing to do", in reality, his actions would have him either demoted, fired or imprisoned. Heck, other team members ended up taking his punishments for him instead.
Latin Lover: But not to Lilly, no matter what the Fandom wants to believe. The Grand Finale shows how much they care about each other though.
Idiot Ball: In "Breaking News", when he learns that Frankie has lied him about being divorced and that she's still married. He is disgusted but when he meets her later in a bar he goes to play bed bondage with her... in the middle of a crime investigation.
Kavorka Man: Has four (way better looking) love interests through the series despite being a short, fat, lazy alcoholic with a hard hearing voice and possibly most definitely infertile. He even uses his 'charms' to get a testimony from a woman in "Two Weddings" (the lady was a tramp, though)
Noodle Incident: His "would have been 19 years old now" son with Megan mentioned in "Ravaged"
Rabid Cop: The resident one through much of the series, yet arguably caught up by (and surpassed) by Scotty in the 7th season.
What sets him off even worse, though, is minority suspects claiming that the only reason they were accused is that the police are racist, as seen in "Death Penalty: Final Appeal" and "Wunderkind."
In Death Penalty Final Appeal he beats up a crooked DA after the guy caused in an innocent man being executed by obstructing the case and having the balls to try to justify what he had done.
Butt Monkey: If there was one teammate who could qualify as this, it's him. Played for Drama against suspects, who aren't ashamed to act racist towards him (in fact, the only other squad member who gets as much crap from suspects is Lilly herself, being a woman), but Played for Laughs among his fellow detectives, especially since he usually takes it in stride. See Writers Cannot Do Math below.
Embarrassing Old Photo: Vera finds a photo of him at his High School prom and distributes copies of it at the station to prove the "hottie" that accompanied Jeffries and he has bragged so much about wasn't hot at all. Jeffries then counterattacks distributing copies of Vera's prom, but Vera is delighted if anything.
Old Shame: The time she fell for a gang member while undercover, resulting in Veronica's conception.
Overprotective Mom: Is very resistant to let her daughter meet her father despite the guy seems to have fully recovered and reinserted in society. The actual reason is that she's embarrassed of their former relationship and protecting her daughter is just a pretext.
Bus Crash: A disputed case. While she wasn't exactly Put on a Bus, her death was off-screen and her funeral never showed up on the series
Dying Alone: Her main fear. She's so obsessed with it that she marries four times in her lifetime. Ultimately happens, as her last husband leaves her, her younger daughter is nowhere to be found and her older daughter is always working
Cowboy Cop: She uses her position as an FBI agent and her former relationship with Stillman to make the PPD re-open her One Case and help her investigate it. As it turns out, she's doing so completely on her own, but her supervisor has to suck it up and let her continue the investigation because his position would be the most threatened if the whole thing was uncovered.
Deconstructor Fleet: George manages to deconstruct the very same show in his debut episode ("Mindhunters").
He was the first Serial Killer to appear in the series, and as such he didn't have any relation with his victims, unlike other previous killers.
He killed more than once and he liked it. His weren't the usual "rage of the moment" killings that make half of the show, but executions planned to the minimal detail.
He knew the cops would eventually come after him and likely planned his interrogation years before it happened. Instead of being caught in their usual interrogation methods, he mocked them and researched the detectives extensively to use their weaknesses against them.
Unlike other perps, he knew (and lampshaded) when to shut his mouth and that he could walk out any time he wanted since the police did not have definitive evidence against him.
He was a rather low-profile guy nobody paid attention to, so nobody remembered him and/or could identify him when the police asked about him years later. This also helped him to commit crimes while working as a caretaker for the Police Department.
Since he gets away with the crime, his first episode is the first (and one of the very few) to not feature the victim's ghost appearing at the end.
Even Evil Has Standards: OK, his definition of "strong woman that deserves to be stripped down, hunted for miles and beheaded like an animal" is flexible enough to include a 14 year-old, but once he decides a target, he goes after that target and no one else. In one occasion he postponed his plans until a mother was separated from her daughter so he had not to threat or physically harm the child.
During interrogation, he implies that he did in fact threaten to harm the little girl if her mother didn't come with him, so it's more likely that he simply didn't want any witnesses or the hassle of trying to deal with two victims at once.
Evil Plan: In "The Woods". He deliberately uncovers the house where he hid the skulls of his victims so the PPD will reopen his case and his mother's, then kills the one woman that escaped him and does not bury her body to drive off the police's attention to the forest, knowing Stillman will not let Lilly go with them for fear of her being targeted by George, while correctly predicting at the same time that Lilly will not give up but go alone to the house to investigate herself. There he confronts her, takes her hostage and makes her shoot him. In the end, the whole episode was a complicated scheme by George to give his Motive Rant and get himself killed by the only person he considered worthy of doing it, while proving Lilly that she could be a murderer too
It's more likely that he planned to kill her; he was genuinely enraged and surprised when Lilly asked him the Armor-Piercing Question "who sold you out George."
Mommy Issues: He was raised by a crazy woman who blamed him for her (non existent) blindness and sold him to a rapist to spare herself of the harm
Not So Different: Thinks this of Lilly Rush because of some similitude in their backstories (both were raised by terrible single mothers and attacked at a young age; he also wanted to join the police but failed the psychological test) and wants her to admit it.
Character Development: Its eventually revealed that the reason he's such a hardass in regards to John is because he was the one who sent his drug addicted son to prison for a series of petty crimes. He comes to reluctantly admit to John that his son going to prison was the best thing that ever happened to him, as it helped him get his life back on track.
Dirty Cop: He was a known associate of various crooked city officials (including the killer in "Jurisprudence") from his first appearance, but isn't revealed to personally be dirty until the Grand Finale, where it transpires that he covered up a manslaughter committed by his son.
For the Evulz: His background is never elaborated on, no Freudian Excuse or anything is ever offered. He just really gets off on breaking people.
Hoist by His Own Petard: He imprisons his latest victim within hearing distance of a church that rings its bells every Sunday, enabling the woman to retain her sanity by keeping track of the days. Therefore, she won't snap like his previous victims, rattling him so much that he makes the error that gets him caught. Then, his attempts at getting Lily to give up like his other victims backfires when he TELLS Lily the name of the hymn the woman was humming even as he entombed her and left her to die. Sure enough, Lily not only realizes the woman's still alive, she realizes where the woman's being held because she grew up in that neighborhood and remembers the church.
Just One Little Mistake: The only reason he was caught was because a local sheriff spotted him driving somewhat erratically.
They Look Just Like Everyone Else: A former neighbor only remembered him because he was the only white guy in the neighborhood. Even the cop who arrested him describes him as polite and well-mannered, "I wouldn't have picked him out of a crowd". He himself states, "I'm not the guy you look at and think "rapist". I'm more like the guy you see at the dentist's office.", indicating that his average Joe appearance is what made it so easy for women to fall into his traps.
Villainous Breakdown: His latest abductee's refusal to break disturbs him so much that it leads to the one little mistake listed above. After Lily saves the last one he completely loses his control.
