My hope is, that's not how Robin ACTUALLY acts. Maybe, since Raven can't control her powers, she's causing a dark, evil influence over Robin, causing the extreme violence & some of his true feelings about Batman to come out.
Once he sees how she affects him, that's the catalyst he needs to help her. Or, Doom Patrol/ Hawk & Dove know Robin, recognize there's a problem, & they step in to help them both.
My kids grew up watching the Teen Titans show on Saturday nights. We all watched as a family, so I'm holding out hope that this isn't as bad as it looks.
