The last time fans saw Cat was in the second episode of Season 2 when she decided it was time to take a leave of absence from CatCo to find new things to challenge her. No details about what brings Cat back into the fold have been released, but maybe she'll finally find out her Kara's (Melissa Benoist) big secret. Otherwise, trying to hide her real identity from her ex-boss while battling this season's big bads could prove to be quite the juggling act for Kara.
Flockhart returns to Supergirl on Monday, May 15 and Monday, May 22 at 8/7c on The CW.
