DCTV started their big day at SDCC with the Supergirl panel and it did not disappoint. In addition to new series regulars Katie McGrath and Odette Annable , Calista Flockhart will be a recurring guest and in the season premiere! Also we also got news that Mon-El will return later in the season but the how and why is yet unknown.
A good thing too he is because if the trailer is any indication then he might need to come back quickly as it looks like Supergirl is ready to stop being human. Also new characters like Morgan Edge and Reign are spotlighted as threats to Supergirl and Lena Luthor. Will Kara be able to get over the loss of Mon-El to regain her humanity or will we have seen the last of Kara Danvers?
Supergirl returns for season 3 on the CW October 9th.
