In the final episode of season 2, Horton finally springs his punishingly complex trap by unleashing a serial killer that has been surgically altered to look like Tessa, a "Tessaganger" or "false Tessa" if you will, on a shockingly credulous Duncan. The Rewatchers consider the Watchers' cyber security, argue about whether false Tessa is on the verge of a moral awakening, and bid Horton an unceremonious farewell.
