One episode has Eliot and Parker go to Fashion Week to sneak into famous hip-hop clothing designer Andre V.'s show. Upon their return:
Hardison: (angry) Did no one think that I might like to meet Andre V.?
Parker mentions in "Ten Lil Grifters" that her first grab was a palace in the Philippines full of shoes. She robbed Imelda Marcos.
Hardison mentions offhand in "The Reunion Job," right at the beginning of Season 3, that he is capable of rigging an election. Nate apparently stored this tidbit somewhere in the back of his mind for six months in which it was completely irrelevant and then made it central to his plan in "The San Lorenzo Job."
Also recently with "The Blue Line Job", where Eliot becomes the enforcer for a hockey team. In an earlier season, he had mentioned watching hockey games for the fights because "You never know when you might have to fight on ice."
One might wonder how an actress as bad as Sophie keeps getting cast as the lead in various productions. Simple enough: she's a grifter. She just cons her way through an audition until she gets the part. The problem begins when she actually has to play a part onstage.
Which then makes you wonder why she never tried "conning" the audience into "believing" she's a great actress (which would in the end be no different to actual good acting).
Because she doesn't do stage acting for the sake of the audience, she does it for herself. It's Sophie's attempt at "honest" self-expression.
Eliot at first seems like just the average Handsome Lech trope. He hooks up with a different girl every week, but besides one ex who appears in an early episode, none of them seem to stick around more than a night. Then I really thought of the Ironic Echo in "The Reunion Job" about knives
Eliot/Girl: Knives are like people. Everything's in context
You know how Eliot always explains away knowing various things as "slept with a ____"? He really pays attention to the girls he picks up, and he learns from them. It's not much, but it certainly plays into the "big softie" theme they have going with him.
It comes up again in "The Lonely-Hearts Job", when Eliot tells Sophie that contrary to her assumptions, he does indeed remember the names of the women he's been with. Of course he does. He pays attention to them. It's how he learns the info associated with their various jobs. It's also why he's so successful with them.
The opening narration mentions that the Leverage team "steals back" things that have been taken. One of the recurring themes is people slighted or humiliated publicly. In addition to money, the team steals back their dignity.
Victor Dubenich says that all a man has in the world are his business, his possessions and his name. So to ruin Jack Latimer the Leverage team sets about stealing those three things, pretty simple. But remember the end of the speech, if you take away those three things "any man will kill" Nate wasn't just trying to bring Latimer down so that he would stop protecting Dubenich, no, Nate was systematically ruining Latimer to the degree that he would be willing to kill Dubenich himself!
In "The Boiler Room Job" it was stated that their mark was a fellow con man who knows everyone they could possibly go to for help. This leads to the obvious question of why he didn't realize who Sophie was given that she is an infamous grifter herself. However she had operated in Europe primarily and so he might not know her as a result. As for Nate and the rest of the team they weren't in his community as grifters as they were involved in theft whereas he was involved in straight cons.
In the Queen's Gambit Job Olivia learned to win from her father, once you know who he is it becomes clear why she always wins.
In the Grave Job, Parker asks Nate how the client knows that their father in resting in peace, and Sophie notices her "off" behavior when she and Nate return to the apartment. She's thinking about her brother, who's death we learned about in the Future Job.
Parker being more upset in the pilot about not being paid than an attempt on her life makes more sense if you remember that security guards would be prepared to kill her with some of the things she'd attempt to steal, which Parker would see as fair enough as they are both doing their job and it's nothing personal. But refusing to pay her is a personal thing as that insults her skills and the effort she put in. Parker isn't really seeing the difference between someone doing their job in trying to kill her and someone double-crossing her in trying to kill her like Eliot does. So she gets more angry about not getting her money.
Over the recent years, Sophie has been teaching Parker social skills and acting. At first, it seemed that it was because Parker has no social skills. Then it became clear in "The Long Good-bye Job": she's training her successor.
Slightly more meta, but Sophie's accents run the gamut from "really good" to "atrocious." You'd think someone would wise up, but like she said, to an American, the subtleties of regional accents are lost. She's not going to authentic, she's going for what an American would expect.
"The Order 23 Job" has Eliot knock out a mob assassin in a hospital morgue and stash him in an occupied drawer. Now, you imagine waking up in a cold, dark, confined place with a dead body.
Watch Eliot's flashbacks very closely and consider what they imply about his pre-Leverage body count. It's... disconcerting.
In "The Long Way Down Job" it is revealed that Nate remembers little if any of stealing a mountain resort in "The Snow Job." While that was one of his drunkest episodes, this sets up the distinct possibility that Nate was too drunk to remember large portions of season one.
That thug was alive later in the episode, however (he was the head of the security team at the pier), so presumably it was a simply Magical Defibrillator that worked as a improvised taser. Note that Leverage (as well as many other shows) confuses tasers and stun guns, using them interchangeably and having them both incapacitate the target. In reality, stun guns are virtually useless as an actual and only work through pain compliance, while a taser is able to actually stun the individual.
Or, perhaps the fact that he was zapped in a hospital and the crash cart was still right next to him explains his still being around later.
"The Frame-Up Job" is played as a light, Agatha Christie-style mystery, which obscures that the villain is one of the most cold-hearted antagonists in the entire series. He's a rich ne'er-do-well who starts out by slowly poisoning his own father. Later, when Nate, Sophie and Sterling expose his partner and she runs to him in panic, he instantly kills her as casually as if he were swatting a fly.
The entire premise of Leverage becomes a source of Fridge Horror when you consider what would happen if the protagonists learned to work together, but were still bad guys. They'd be a con artist version of the Justice Lords. Thank God Nate made them realize that Good Feels Good...
If the Leverage team didn't do what they do then a lot of people would be dead if the team weren't around to save them.
Chaos has almost definitely murdered people in cold blood.
Fridge Logic: How is it they get to the roof in the pilot episode? It was stated that the roof was their way out but it never explained how they got there in the first place. This is actually a common occurence in several episodes that they simply appear there. Parker's Offscreen Teleportation is also used in a similar manner. Sometimes it would actually be an easier explanation if she could actually teleport.
One issue in the pilot is what happens to the overall economy when Bering Areospace tanks, especially since Hardison short sold stock against it. Similarly given that the company was under serious FBI investigation wouldn't the SEC investigate those trades heavily?
Why haven't they ever ran into a facility with air ducts that Parker was too large to crawl through? In reality there is actually a DOD standard for exactly this. In "The Inside Job" the firm was smart enough to put lasers inside a ventilation duct, why didn't they simply make it too small to crawl through?
