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.
For instance, "Calvin, reptile with a heart of gold ... or giant monster that wants to eat the planet?"
The "Grim Reaper" Memphis works for may very well be some other cosmic reality-warper. The details are infuriatingly sketchy. Memphis, of course, doesn't really care.
For Memphis' part, a social musician at peace with what he is? Or a vampiric monster who sees everyone he meets as food? A little of both.
Angst Dissonance: Casimiro, you mention him your "dark" past? He'll be sure your future is darker out of his lack of sympathy for everyone and everything.
Angst? What Angst?: Harper was separated from her parents, and the ability to lead a normal life, by the London Blitz and a roaming vampire. She's remarkably upbeat about it. Slightly justified, as it's been nearly seventy years since her loss.
Archive Binge or even Archive Panic: YMMV because though reading the whole of the site is at least on par with reading the whole of T Vtropes itself, it is not remotely necessary to understand the setting or any given event.
Jerkass Woobie: The universe craps on Lucas a lot, but he usually earns it somehow.
Like You Would Really Do It: See "Death Is Cheap". In particular, there was that one storyline... (Though that one actually did scare a few members for a short while.) Even so, if someone kills off their character without mentioning the plan beforehand, it tends to come off as something of a shock.
Lucas Greenwood is always hurt somehow, and while comical most of the time, some authors can't but feel bad for the unlucky guy... Then again, he could also be the Jerkass Woobie we mentioned before...
Samantha Chase was created with the intention of being adorable through the torture she experiences.
Wangst: Ryan Nevis has a bit of it, though he's not alone.
