WARNING: SPOILERS/NSFW - DC on SCREEN Podcast #124 - Supergirl 1x15 - Solitude | Review - It's Supergirl vs Blue Supergi--er, Indigo!  Laura Vandervoort, the Supergirl of 'Smallville' is playing Indigo, otherwise known as Brainiac 8!  But that's literally the least interesting thing about this episode!  Winn is recruited (again) to work for the DEO (right before playing tonsil hockey with Siobahn Smythe), Lucy breaks it off with James (FINALLY), Alex finally tells Kara the truth about who killed Astra, and the writers get silver age on this shit with Kara visiting Superman's Fortress of Solitude and opening it with a giant key made of a million tons of condensed dwarf star!
