Superman returns to the season finale of CW’s Supergirl. Tyler Hoechlin, who plays Clark Kent/Superman in the CW’s Supergirl series will make a much-anticipated return in the season 2 finale. He hasn’t been seen since the second episode season 2. No word yet on what the season finale will be about, but we do know that Katie McGrath, who plays Lena Luthor, has been bumped up to a Season 3 regular. With a Luthor running things and Mon-El’s vicious mother (played by Lois & Clark alum Teri Hatcher) on the loose, anything is possible. Stay tuned for details on the season finale.
