Barry and Iris are sending some "Mixed Signals" to each other after trying to get back to a somewhat normal life. Barry is walking on sunshine with his return, but Iris really wants to confront his decision to leave. While tackling couples therapy they have to also try to stop the mysterious hacker Kilg%ore, who has the ability to link himself into any piece of technology, and of course he has a serious digital axe to grind. He's out to kill the three former partners who stole his idea and struck it rich. Plus, Gypsy stops by for an epic date-fail with Cisco. Jay and Josh celebrate One-One-One Day on this week's episode of Scarlet Velocity: A Flash Podcast!
