The Ace: Sean was selected to appear on the show due to his EB-1 visa for "persons of extraordinary ability". He went on to have an unbeaten record as a project manager of the winning team, and has won more tasks than anyone else who appeared on the show.
Beware the Nice Ones: For the most part he was a charming guy, but was more than willing to become mean when needed.
Romance on the Set: With Tammy, one of the more visible examples of this trope during the show's run.invoked
True Companions: Quickly became this with Lee after they ended up on the same team together. He also appeared to be this with Andrea, from the way he defended her in the boardroom where she was fired and then brought her onto his finale team.
Unusual Euphemism: A variation; he referred to both Michael and an ineffectual contractor as a "wanker," which isn't that unusual a euphemism in his native UK, but is much less commonly heard in the US.
We Used to Be Friends: With Allie and Roxanne, after they turned on him when he tried to defend Andrea in the Week 9 boardroom. It was turned up a notch when they got Tammy fired after the second-last of the regular tasks. In the finale episode they at least managed to patch things up to the extent where they were actually able to talk to each other, but he was in absolutely no hurry to have either of them on his team.
Lee
Butt-Monkey: Constantly ended up in the final boardroom, despite almost never deserving to be there.
The Cassandra: Usually managed to point out what the team was doing wrong, which almost invariably resulted in him being ignored, and still being brought back into the boardroom anyway.
The Friend Nobody Likes: He held this status between Lenny's firing and Sean arriving on the team. Not because he was nasty at all though, more because his team adopted a "complainer is always wrong" attitude.
Last of His Kind: After the double-firing of Charmaine and Tarek in Week 10, he was the last of the original Gold Rush members left.
Nice Jewish Boy: Despite occasionally coming across as a politician, he had a generally very agreeable personality. He, alongside Dan, also took Week 3 off to observe the Jewish New Year.
True Companions: With Lenny at first, then Sean after he got moved onto Gold Rush.
Allie
Awesome, but Impractical: The most charitable way of describing the uniforms she made in her final task, which looked like what a comic artist from the 1930s might have drawn if you asked them what they thought hotel staff would be wearing in the year 2006.
Bitch in Sheep's Clothing: Appeared nice for the first half of the season, but a much uglier side of her emerged after she lost in her second turn as project manager.
Chronic Backstabbing Disorder: For someone whose personality wasn't actually that nasty she was one of the show's worst competitors in this regard, doing it to Brent, Andrea, Sean and Tammy over the course of the season. It finally ended up with her and Roxanne trying to do it to each other after the final regular task, which resulted in Trump firing them both.
Crippling Overspecialization: Actually very good when it came to sales, but she wasn't especially good at much else.
My God, What Have I Done?: To give her some credit, after getting fired she realized just how awful her behavior toward Roxanne in the boardroom had been, and also seemed remorseful when she met Sean again.
Roxanne
Chronic Backstabbing Disorder: Not quite as bad as Allie in this regard, if only because she correctly blamed Pepi for the Week 2 loss instead of joining the rest of the team in trying to throw Brent under the bus.
Tragic Mistake: A very strong competitor, but she killed her chances by allying herself too closely to Allie and then turning on her viciously in the final boardroom of the season. In that regard, she's essentially an Expy of Alla from the previous season.
True Companions: With Allie. They were a very strong unit when they worked together well, but when they didn't, things got ugly.
Tammy
Ironic Echo: She got fired for producing an Xbox 360 display which Trump said "stank," the exact same word that got Brent fired several weeks earlier.
Nice Girl: Stood out as this in the second half of the season when compared to the much bitchier Allie and Roxanne, and the haughty Andrea. It's little wonder that Sean was attracted to her.
Michael
The Friend Nobody Likes: Not to nearly the same extent as Brent (and probably not even as much as Lee), but as the competition went on, his teammates really began to tire of his indecisive nature.
Overly Long Gag: In his turn as project manager he spent an hour at a hardware store just deciding on paint colors for the room they were meant to be renovating. He even called a few of his teammates via cellphone to ask if they should paint the room's pipes different colors from one another. Said teammates couldn't help but crack up.
What Were You Thinking?: The reaction of his teammates when they learned that he was willing to share their cheerleaders with Synergy, which would probably have resulted in Gold Rush taking even more of an ass-kicking than they really did. It was the biggest reason for his firing in Week 11.
Tarek
Exact Words: The "gift bags" that he gave away in the first task were exactly that: empty duffle bags. Even when George pointed out that people usually expect gift bags to actually contain gifts, he still didn't see anything wrong.
Genius Ditz: A member of MENSA, but he really screwed up big throughout the season, causing Trump to joke more than once that MENSA should probably rethink their admissions process.
Jerkass: Showed varying shades of this throughout the season, but it came to a head in Week 10, when his refusal to co-operate with Charmaine and nastiness to her in the boardroom got him fired.
Karma Houdini: As Trump himself pointed out, he deserved to be fired after the first task, but survived due to Summer's stupidity.
Charmaine
Arch-Enemy: For much of the season she was this with Lee and Lenny, the former because she thought he complained too much, and the latter because he tended to be fairly dismissive of her (which, to be fair, was a valid complaint). However, there was the undercurrent of a rivalry between her and Tarek for much of the season, and in Week 10 it just exploded and got them both kicked out.
Captain Oblivious: In Week 10 she told Bill about how well the task was going and how hands-on of a leader she was... while she was getting her hair done in the middle of an otherwise empty salon.
Misaimed Fandom: The comedienne she hired in Week 3 offended at least 50% of the GM executives, and was a major factor in the team's loss.invoked
Skewed Priorities: In her final task she thought that getting the team's hair salon set up to absolute perfection should take priority over actually marketing it, or coming up with some sort of promotional theme.
Andrea
I'm Not Here to Make Friends: She didn't actively go out of her way to offend people, but at the same time cared little about whether or not people actually liked her. Had she been a little better in this department, she would have had a very strong chance of winning.
Non-Gameplay Elimination: A rare instance of this happening after she had already been eliminated; she came back as part of Sean's team in the finale, but had to leave due to a sinus infection.
The Scapegoat: The team tried to turn her into this in Week 4, for designing an overly-complicated advert, but it ended up not mattering when Brent got fired for going into douchebag overload. When it happened again in Week 9 however, it led to her being fired.
Leslie
Beware the Nice Ones: The one time that she really stood out was in the Week 5 boardroom, when she lashed out at Dan for making himself the project manager without actually asking anyone on the team whether or not they'd be qualified to lead, and also for ignoring her advice when she had broadcast journalism experience.
The Generic Girl: Made very little impression throughout the season, meaning that when she eventually stood up as project manager it was too little, too late.
Lenny
"Blind Idiot" Translation: Lampshaded in Week 6; since he still only knew English as a second language the only way he could try to write jingles was to write them in Russian and then translate them to English, which just produced garbage.
Funny Foreigner: He didn't speak that often due to there still being something of a language barrier, but when he did it was usually with a very good one-liner. Trump even said that he would have made a better comedian than the one that Gold Rush actually hired.
The Scapegoat: Theresa tried to turn him into this in Week 3 after he failed to hire an electric generator. A big screw-up for sure, but as Bill pointed out, it really had nothing to do with why they lost the task.
Bryce
Honor Before Reason: After losing as project manager he could probably have saved himself by bringing back Tarek and Charmaine, the former of whom was already hanging by a thread and likely would have gotten fired. Instead he brought in Lee (who didn't even participate in the task since he was observing a religious holiday) and Lenny (who couldn't write jingles due to not knowing English well enough), saying that without Tarek and Charmaine they'd have had no music or lyrics. This naturally got him fired.
Dan
The Caligula: He suddenly turned into this as project manager in Week 5, getting a 0% Approval Rating from the rest of the team. It continued into the boardroom, eventually earning him and the others a reprimand from Carolyn, for acting like "a bunch of schoolchildren."
Insane Troll Logic: He realized that if he brought Lenny (who came up with the ad concept that the executives hated) and Lee (who he just didn't like) back into the boardroom, they'd gang up on him. So, he decided to bring back... Lee without Lenny. If he wasn't already likely to get fired, this made it certain.
Brent
Big, Stupid Doodoo-Head: In his final week in the competition, Andrea called him "a liability to the team" during the initial boardroom. Brent's response was "Oh, yeah? Well, I think you're a liability!" Andrea's reaction made it clear that this wasn't quite the devastating insult that Brent apparently thought it was.
Crazy Enough to Work: His robot dancing in a bathrobe was about the only reason the team even did as well as they did on the second task.
Fat Idiot: In fairness, he wasn't completely the incompetent nitwit that his team made out. His major problem was more how obnoxious he was.
The Friend Nobody Likes: Aside from Stacy R. in Season 2 and Omarosa in... well, every season she took part in, perhaps the show's all-time biggest example of this. About the nicest thing that anyone said about him during his time on the show was when Roxanne said in Week 2 that he technically wasn't responsible for the loss despite being a major pain in the butt.
History Repeats: The way he got himself fired was more than a little reminiscent of how Toral had gotten herself fired in the previous season — right as the rest of the team were piling the blame on someone else (Felisha in Season 4, Andrea this season), he spoke up at exactly the wrong time and managed to get himself fired.
Jerkass: Granted, it's not hard to see why he might have felt bitter at the team given how they treated him like crap from the minute the show started, but he openly wished horrible things on his team-mates in the Confession Cam inserts.
After the second task, the rest of the team tried to blame his argument with Stacy early in the task for their defeat. Bill pointed out that while this probably didn't help, their bad location and worse promotional strategy were to blame.
Subverted in Week 4, when the team realized it'd be pointless trying to blame Brent (since he hadn't been assigned any tasks; they decided to make him step up as project manager the following week in a Springtime for Hitler gambit) and decided to make Andrea into the scapegoat instead. At which point Brent managed to turn himself into the scapegoat with an out-of-nowhere insult aimed at Tammy, which caused Trump to fire him for just being too much of a douchebag.
Buxom Beauty Standard: Inverted and lampshaded by Lenny when she was project manager, when her indecisiveness caused him to say "I wish her brain was bigger than her boobs."
Honor Before Reason: Refused to bring Charmaine back after losing as project manager because she'd worked hard, even though Charmaine failed to brief the team's models and hired a comedienne who bombed horribly. This ended up being the main reason why she was fired.
Never My Fault: Didn't take any accountability for the third task's failure, instead trying to place the blame on Lenny's shoulders for losing track of the stage's power generator - a minor issue that was quickly resolved by Bryce in any case.
Pepi
The Generic Guy: Played for laughs in the season finale, when Trump couldn't even remember Pepi ever being a candidate on the show. Carolyn also didn't remember him, although that was probably because Pepi was on the winning team in the first task, and Ivanka was filling in for Carolyn the following week when he was fired.
Stacy
Jerkass: Decided that the best way to deal with Brent was to constantly interrupt and talk over him, to ensure that he didn't get the chance to waste the team's time. He naturally didn't take kindly to this, resulting in him confronting her about it, after which things went totally off the rails.
Spanner in the Works: Despite her attempts to scapegoat Brent after the second task, she was really the one most at fault for the failure, as she blew her confrontation with him out of proportion (resulting in the argument that took up most of the first day), and then chose a horrible location which buried the team.
Summer
Dumb Blonde: Came across as this throughout the first task, especially when Trump was about to fire Tarek, only for Summer to interrupt and try to "tell the truth about Tarek," which got her fired instead.
