These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Asshole Victim: Agent Gardiner could qualify, although this depends on whether one considers him either a loyal CSIS Agent doing his job to investigate a mysterious woman whose story doesn't hold up, or simply an Inspector Javert deliberately seeking ways to antagonize and implicate Kiera for any crime whatsoever.
The Chris Carter Effect: As the second season has progressed and more characters are introduced or revealed to have their own agenda, it's 50/50 whether week to week things are being thrown at the wall and seeing what sticks or if there's a master plan and the series is falling into this or Gambit Pileup.
Jerkass Woobie: Kellog seems to be a classic Con Man, Manipulative Bastard and Punch Clock Villain abusing time travel for his own gains. Then he had to watch the woman he thought/might be was his grandmother die in his arms due to his former comrades trying to blackmail him and his own back story implies he only joined up with Liber8 after he was wrongfully arrested because he stayed with his dying sister (the real Liber8 member at the time) in her last moments when the arresting officers fired upon them it is really hard to not feel bad for the guy. And he gets to witness the Charlie Foxtrot that the Liber8 inspired timeline becomes, as he becomes one of the last holdouts after a series of devastating inter-corporate civil wars.
Foe Yay / Les Yay / Bi the Way: Garza for Kiera in a kind of weird one-sided way. Along the way she also throws a smooch at Fonnegra. Then again, she likes trolling Kiera, who seems a bit straitlaced in the realm of sex.
Season 1: You'd think Sonja, a genius doctor, would know how to make sure someone's dead. She must have self-sabotaged.
Season 2, Episode 6: Kiera comes out to Carlos about being a time traveller. Of course he things she's nuts. Why didn't she just show him that future tech super suit she wears everywhere? Or demonstrate one of her cyborg superpowers?
Moral Event Horizon: Even though the entire season was building up to Past!Alec being evil, it could still have been argued that he was at least well-intentioned. Then comes the season finale, where he taunts Future!Alec by claiming that he will do everything in his power to keep Future!Alec from being happy with Emily, even if that means killing her, and uses his dying breath to rub Kiera's lost family in her face. Even before that, he tries manipulating her by mentioning her lost family.
Paranoia Fuel: Quite a bit of what Liber8 is fighting against is disturbingly plausible. And some of it has already happened. Kagame explaining how the banks dodged responsibility for the 2010 crash is a good example.
"Minute of Silence" gives us Amateur Autopsy Hour with our host, Alec Sadler. Who needs proper tools when you have a power drill and a hole saw?
Special Effect Failure: When Past!Alec is stabbed in the neck and then pulls it out, the resultant blood spurt is pretty...lackluster. The neck has some pretty big vessels, and arterial spray is known for flying feet from the victim if it's a big enough hole (given the object he was stabbed with, it had to be a big hole). There's also the way it squirted more after he'd already collapsed, rather than an initial surge of blood and then weaker dribbles as his heart ran out of blood and ceased pumping.
Stop Helping Me!: More than once, a hostage has professed to agree with Liber8 and gotten shot by Travis for doing so.
Tropes for the tabletop game
Paranoia Fuel: Any leveller in history or even other spanners could be replaced by a Thespian.
