I guess there really isn't any kind of scale for lower-scale Metahuman crimes...you get convicted, for anything, you get sent to Belle ReveProbably public mischief offenses and trespassing on private property (the water supply station). If at any time in those three years, she fled from the police - intentionally fleeing the scene, too. Once Waller got wind of Nina in the news, had her transferred to NHID.

Honestly a part of me wonders if they should have just kept Matthew Shrieve as the leader because I'm not sure if this was a good introduction for Flag Sr....though then it wouldn't have been a good use for him because they needed an excuse to put Bride in chargeIn the Dec. 5 interview on DC's Youtube, he did say he looked at a list of DC characters that could be on the team and then admitted the original comic book roster, Nosferata, and any gorilla/ape/monkey DC character were all considered.

Probably in season 2 tooFeels like that was the point and will be picked up by another series and/or movie.
Also the most faithful to John Ostrander and Kim Yale's interpretation of the character, fittingly enough...Animation hasn't really nailed a good take on Waller aside from JLU, imo.
