The first trailer for Supergirl's return this January shows us a lot of different things: Roulette returns, something happens to Winn Schott in the field, and Supergirl goes through a portal and ends up on a world with a red sun… not good for a Kryptonian. Could this be Warworld? Might we be getting Mongul? That would be huge and yes I'm totally speculating. This episode is directed by Kevin Smith and called Supergirl Lives… I wonder if there will be a giant spider in the third act?
