The promo focuses on the central plot of the episode, starting with Kara getting a phone call at work.
The episode ends with Supergirl getting the bad guy (obviously), and with her getting a little bonus, too: Kara has her job back at CatCo.
The episode also focused on Kara’s relationship with Lena Luthor (Katie McGrath), and Lena’s fear of becoming as ruthless as her mother.
Supergirl returned to The CW this week with ‘Ace Reporter’, an episode that returned to the show’s roots by pitting Supergirl (Melissa Benoist) against a big bad borrowed from the comics.
