SPOILERS/NSFW - DC on SCREEN #153 - Supergirl 1x19 - Myriad | Review - It's Maxima, Myriad, and Maxwell Lord in this penultimate Supergirl episode! Everyone in National City is under mind-control except Maxwell Lord, Cat Grant, and Supergirl. Alex and J’onn J’onnz make it to Alex and Kara’s childhood home only to learn of what’s happened in national City and head back.  Max wants to use a bomb that will take out the Kryptonians (and about 300,000 humans), but Kara and Cat have a different (and less sure) plan involving hijacking old television signals.
