Wait, was Severa not loud enough? No, that can't be it. She can read this other person's face pretty well; she's just clumsy, not stupid. "You... do work out, right?" Is this somebody with natural strength? Or another superhero? No, she'd probably recognize her if she were another superhero. So... she's just ridiculously strong. To the point where she probably could dead lift a motorcycle. And Severa just pissed her off, probably. Well, this'll be fun from here on.
