This episode of Flash has enough flashbacks in it that it could have been part of Arrow.
This episode of Flash parodies a comedy classic for its title with, “When Harry Met Harry.”
Barry and Iris’ wedding is creeping closer, and on any tv show that means it’s about time for some kind of disastrous and/or humorous bachelor/bachelorette party. The title “Girls’ Night Out” should give you an idea about what they’re going to be focusing on, although we see a bit of both sides. It’s also an excuse for a guest star or two, and a new introductory voiceover.
The writers on the various CW shows have been doing a good job of going through DC Comics archives to find random and often obscure characters to bring to live action, often for the first time. This week, they use one that actually did start off as a supporting character for the Flash before going on to join the Justice League.
Last episode, lurking bad guy The Thinker hinted there were more new metas for Team Flash to deal with. That’s a big part of this episode, as the team faces a new version of a minor DC Comics character.
“Mixed Signals” brings back a villain from the period in the comics when Wally West was the Flash.
Flash hits the end of his season with “Finish Line,” the season three finale. The heroes need to find a way to defeat the menace of Savitar, which gets harder with Savitar being a future version of Barry Allen. So whatever plan they come up with, Savitar knows about from Barry’s memories. That’s a new wrinkle on time travel I don’t think I’ve run across before. There are some pretty big spoilers here, so be warned. Don’t read this if you haven’t seen it.
