Having identified one of the remaining Worldkillers, the DEO mounts up to get her before anything bad happens in this week’s Supergirl. That...kinda backfired.
There were a lot of plates spinning in this episode. There's the awakening of Wordkiller Purity, Alex being more aggressive than usual, Ruby getting abandoned at an ice rink, Sam having a blackout in front of Lena, marital issues between Imra and Mon-El, and a bombshell pre-reveal being dropped at the end. Whew! Let's try to break this down, shall we?
