With the newest revision to Supergirl's 5th season and the announcement that Melissa Benoist is pregnant, Supergirl might not return to The CW until 2021.

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!
