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.
Narm: The lower-teeth-over-upper-lip face Toby keeps pulling when he gets excited doesn't make any sense. If the author was aiming for Creepy Child, he merely hit "dorky". He's probably trying to represent him experiencing something like a seizure.
Invoked by the Revenant when discussing Harold's power nullification and enhancement abilities. A lot of supers have a very bad response to the idea of someone messing with their powers.
Some of the alternate versions of himself Tyler sees in the mirrors at The Castle Beyond Time and Space are pretty nightmare-inducing. In one he is a powerful telepath who has accidentally linked everybody else together in a hivemind, making him the only lonely person in the world (see Gone Horribly Right in the main page). In another, he is the strongest meta-prodigy at PS238 - and uses his power to harm and bully everybody else. Imagine seeing your friends being bullied - and then imagine that the bully is you.
