So it was Luke Skywalker after all.

Criminal Minds' season-long unsub/stalker The Replicator was finally unmasked on Wednesday's two-hour finale as Mark Hamill's federal agent/biochemistry nut John Curtis. At the end of the first hour, Curtis breaks into Strauss' (Jayne Atkinson) hotel room, after which he forces the recovering alcoholic to drink before drugging her with "Doctor Death," the meth/ecstasy mix at the center of the case the BAU had just solved. He lets Strauss wander the New York streets, where the section chief dies on a bench in the arms of Hotch (Thomas Gibson) — not her BAU-member-with-benefits Rossi (Joe Mantegna).
