Harrison Wells from Zoom’s dimension is there to help them stop Zoom before he takes their world, but Team Flash isn’t sure if they can trust him. Another villain from Earth-2 arrives and blinds Barry with her ability to generate bright lights.
Some interest relationship dynamics, which is odd for me to say since I haven’t really been enjoying that on Supergirl lately. But here, the one between Jay and Caitlin is neat as they both seem to have a lot of pain in their past. And I like how Barry and Peggy seem to work well as a couple, and as he’s blind for their first date is funny in a romantic comedy sort of way until Peggy flips it around by figuring it out because she’s that good of a detective.
Actually as an episode that was much, much higher on drama than it was action, this was a very good episode.
+10: Very interesting, character-and-relationship-building episode
