It's Barry's bachelor party and the gang is saved from having to watch Cisco's painstakingly put-together film reels of childhood Barry and Iris by an unexpected guest: Ralph Dibny. Let's get the fellas out of the way, shall we? Essentially, their narrative in this episode boils down to a bro-down.
The episode does so by letting the ladies and the gents have their own adventures without worrying so much about threading the two together. However, "Girls Night Out" actually checks the boxes on all of these plotlines in different ways, and successfully so, which is a bit of a surprise. We've got Caitlin’s shady past under the crime boss Amunet coming back to haunt her, Cecile’s pregnancy and the physical/psychological complications that arise from it, the team’s search for the mysterious DeVoe and the rest of the 12 new metahumans, and the continuing adventures of The Elongated Man, a.k.a. That's good because The Flash is currently juggling a lot of storylines, as this week's "Previously on." makes very apparent. While I thought that we'd be tagging along with Iris, Cecile, Caitlin, and Felicity (yes, Arrow star Emily Bett Rickards makes a guest appearance), the episode actually split the party along gender lines for two separate stories that had just about nothing to do with each other for once. Tonight's episode of The Flash is titled "Girls Night Out", so of course I'm the best possible flavor of recapper to handle this particular hour. Your regularly scheduled recapper Carla Day will return next week!
