- Title: Supergirl – Both Sides Now
- wiki: link
After catching Purity (Krys Marshall), and getting a glimpse at (but not really understanding) her duality, Kara (Melissa Benoist) and Alex (Chyler Leigh) disagree on how best to interrogate the world killer. After she escapes from the DEO, leaving chaos in her wake, the pair are forced to put their debate on hold while the team heads out for an underground climax in a National City subway station. Meanwhile, Sam‘s (Odette Annable) day off with her daughter leads to yet another unexplained disappearance and plenty of questions for Lena (Katie McGrath) who may finally be the first to suspect what’s really going on with her #1 employee.
The episode’s B-story throws the guys together as J’onn (David Harewood) attempts to help Mon-El (Chris Wood) repair the ailing Legions spaceship and fills in some of Mon-El’s relationship with Imra (Amy Jackson). Taking the Martian Manhunter’s advice and being truthful to his wife about his confusing feelings for Kara leads for a shock for Supergirl’s ex, as he discovers there is more about the Legion’s appearance in this timeline than just chance. Why are they here?
