You betrayed the team often, so your return was not a pleasant thing for the team. None of the Titans trusted you, Robin was biased, Beast Boy and Cyborg were biased as well. Only Starfire would accept you back, but if you stumbled again, she would "destroy" you.

Now Raven was reading a book on the living room couch. You walked over to her and sat down next to her. She didn't even pay attention, to you, but after you defiantly started staring and oohing and aahing, she looked at you closing the book. "why are you here?" She asks in a serious tone, even though she already realized that it's obviously not because you've changed.
