She's actually the one to defend Ravager's place on the team to the other Titans in the meeting after this, once Bombshell explains what Rose was doing. She's being harsh with Rose, but Rose is also being a bleeding moron who's doing her absolute best to come across as poorly as possible, so it's not like either of them is doing anything to alleviate the "cats in a sack" dynamic they've got.
Frankly, I say we just lock them in a room together and forget them both. Either they beat the shit out of each other and we never have to worry about either of them being stupid McKeever puppets again, or they resolve their UST, get a good fuck and get over it. Both options lead to a happier, less annoying Teen Titans.
