Actually… maybe not. If this is Mysta in the False!Maria costume before the transfer occurs, then she might not have the skin sections yet and they appear later. Special or lighting effects could cover her for a few seconds as she takes them off to show the ‘newly developed’ skin.
I don’t think it’s going to be anything lethal. Ralph doesn’t know who Mr Roboto is, and other than, say, telling the police meeting places, can’t really give them any information. Roboto can’t risk using him again in case someone in the bank, probably the cashier, can describe him so the police could trail him to try and get leads to the gang.
Mysta got punched so hard her ropes broke…
