Good idea I'm sticking with:
Gloves is either the head of or high up in a mafia-type organization that keeps tabs on infected people, especially those who do vigilante work or other illegal things. When Tabbi comes up on Sissy in the park she's trying to get someone to pay up or something.
I decided that that someone is Aimee, but you don't actually meet her for a while.
Tabbi being a "magical girl" in 6th grade. She tried being a superhero, fighting for justice at an afterschool program she was enrolled in in a Halloween costume.
I may actually use this. Because you know she's try it.
Also, Darby's powers: WTF should they be? D:
