Returning characters Cat Grant and Superman will play pivotal roles in the Supergirl season 2 finale.
Cat Grant left the show after season 1, when Supergirl moved from CBS to The CW (and filming moved from LA to Vancouver).
Talking to EW, executive producer Andrew Kreisberg promises a big role for both Cat and Superman in the finale.
The description of Cat and Superman’s return as “shocking” is particularly interesting, as both are still alive and in some kind of contact with Kara (Superman more so than Cat, of course).
