I think that it may be either Artemis or Miss Martian. I'm not entirely sure. KF, Robin, Red Arrow, and Aqualad are basically in the clear. However, it may be Zatanna. I doubt it, but we should keep our options clear. I'm not sure what you mean about the g-gnomes being connected to Sportsmaster. Sportsmaster was simply working for The Light, it just happened that the g-gnomes were too. Again, like batman said, Superboy could be the toupeira and not even now it. The Light has already proven to be a very cunning and resourceful organization. So, overall, there are 4 suspects: Zatanna, Artemis, Miss Martian, and Superboy. @KidFlash2001: Yeah, we know that now. I knew a while ago.
They never said the toupeira was on the Team,did they?I bet it's one of the leaguers,like batman or Flash. I mean, they have access to the Team's info ,too.It's not like the Leaguers haven't been manipulated before. Who's to say that it's not a Leaguer? I think it's Zattara,Batman,Green Lantern,Flash,or Red Tornado.
The toupeira is obviously someone no one would think it is like Red Arrow, Robin, or Kid Flash cuz really think about it in Teen Titans Robin betrays his team for slade/death stroke because slade was threatening his friends and both Kid Flash and Red Arrow/Speedy both like villans.
