Let's sing Grease! Barry and Caitlin take a night off, where Barry is hit upon by someone other than a super powered villain and Caitlin reveals a propensity for Vodka. While not as dangerous as a hang over, the Flash and the team are faced with a woman with the power to teleport a la Nightcrawler and an imprisoned love interest with a debt to a local crime boss. Also, Cisco finds himself unable to ignore the arrogant overtures of last week's villain, Hartley, who promises the truth of what happened to Caitlin's fiance. Also, GROOD.
