Sinister has plausible deniability… Xavier: Sin-is-TERR! Sinister: I didn’t do it, it was the clone! Xavier: who made this clone? Sinister: that other clone! I’m innocent!
Re: wrapping up a plot line. Sinister can’t keep torturing Psylocke forever. In his Secrets page, he seemed to infer that he knew she’d come to a breaking point.
Wells will run out of horror movie references eventually. We’ve had Night of the Living Dead, Arcade/Jigsaw (or Chucky, as Sinister called him), Mastermind (Freddie Krueger), and the Locus Vile is like Jason and Ghostface were adopted by the family from Texas Chainsaw Massacre or Night of a 1000 Corpses. Nanny/Orphan Maker died and came back weird, like Pet Semetery.
We still have the killer Smiley crew out there, and a resolution with Maddie (Carrie?) is needed.
