Haaaaaa. Didn't put this in the official "story" cause she doesn't kill many people at the time it takes place, but I just kept imagining scenes of her in mu head. She's a fun one :>
Characterization idea for Eva: when she gets really excited she gets all jumpy and just HAS to mess with something so her signifying thingamabobber for when she goes out and kills people is a rapid clicking sound caused by a bottle cap or one of those animal caller clicker things.
Because of this habit and her over excessive amount of energy, Goo calls her Jitterbug sometimes
