I wonder what they're going to do with him. If TITANS is folding and half the team is splitting off to be in Robinson's JLA, Gar's got nowhere else to be (well, Doom Patrol maybe, but that gets retooled even more frequently than the Titans). But we know from interviews that Cassie's eventually going to stop waffling and lead, which leaves him... what, skulking around the tower as 2nd-string supporting cast like back in the early Johns days? Seems an odd reason to bring him over.
