We can all agree that this might be one of our favorite The Flash episodes of the season, or for some, maybe even the series. So whether you missed it or want a quick recap the episode starts with Mon-El and Hank Henshaw arriving carrying a comatose Supergirl, who was attacked by the Music Meister.
