With Rhea (Teri Hatcher) having killed her husband and determined to return to Earth to get Mon-El (Chris Wood) and take down Supergirl plus the dangers of Cadmus, the Girl of Steel has a lot on her plate all while building towards the season finale. Melissa Benoist talked with EW.com about the finale:
She's going to have to figure out how to balance it all. There might be people she has to ally with and people who will be her clear enemies, so it's a lot of juggling.
There seems to be a building theme of making questionable allies here and with Arrow. At least we know that her Kryptonian cousin will be coming by to help.
Supergirl returns April 24th to the CW.
