I'm going on the record right now declaring that this episodes title is (a) a lie or (b) better be a lie.
This season's big bad, Cicada, wants to finish what he started with Vibe: killing him. Why he picked Vibe over Flash, or even Elongated Man, we can't say. Guess a man's got to have his priorities. Meanwhile, Team Flash is on the hunt for Cicada, who we learn from XS is a sort of metahuman serial killer -- who was never captured; not by Team Flash, the Legends, even the League (yes, that's a reference to a future Justice League).
XS's plan to find Cicada involves bringing in a detective. And it's not Ralph, which has to sting. No, it's time to approach... the Council of Wells. Yes, the WORST idea ever to inhabit the Flash Writers' Room is back -- or at least one of them is back. And he refers them to yet another Wells we've not yet met: Sherloque Wells, consulting detective with a string of ex-wives to whom he owes alimony.
