'Yes, I've been gone for a while, but I'm back,' says Cat Grant to a live TV audience at a key [...] - From DC
While the reasons behind Grant's departure -- Flockhart's inability to relocate from Los Angeles to Vancouver when the show got picked up for its second season -- are not story-driven, this week, her tale very much seemed like it was hinting at a more permanent return.
Besides "tidying up" her office, essentially complaining about and occasionally removing the tchotchkes placed there by her successor in the office, James Olsen, she ended her speech with a defiant "I'm not going anywhere." There has been no indication that Flockhart has changed her position on moving to Vancouver, although with upfronts coming on Thursday and The CW ready to announce a series of casting and scheduling moves, it's not implausible that they found some sort of deal with the actress that would allow Cat to appear, if not as a regular then at least more frequently in season 3.
It has also been a season about mothers, and whatever happens next week, it seems likely that Mon-El will lose his.
It might be a poignant (if painful) parallel for Kara to lose one of her maternal figures, as well.
Supergirl is based on the characters created by Jerry Siegel and Joe Shuster and appearing in DC Comics, by special arrangement with the Jerry Siegel Family.
