Chyler Leigh posted a VERY convincing new image of herself dressed as Supergirl. The costume looks like a merge between a DEO/Supergirl costume. See here!

We've been seeing several sources stating that Wondergirl, Conor Leslie isn't done with the Titans yet. Expect to see her back in some form in season 3.

According to Discussing Films, Titans season 3 is looking to bring Barbara Gordon onto the show. This would be the Oracle version of the character, post-Batgirl.

It isn't known yet who will take on the role of Roy Harper (mentioned briefly on a phone in season 2) for Titans Season 3, but insider Vullein says the role has been filled!
