It’s a fair bet that my readers include at least one Mutant Enemy fanatic. Got a couple of canon questions for ya.
In Buffy the Vampire Slayer, anyone seen smoking is either evil, under a spell or doomed. (There’s one exception: Mrs Epps in “Some Assembly Required”, who seems to spend her days watching her dead son’s football triumphs on tape.) I didn’t notice whether the second vampire to acquire a human soul then stopped smoking.
In Firefly episode “The Train Job”, the sheriff of Paradiso shares a cigarette with a prisoner. Is anyone else ever seen smoking in that universe? I can easily picture Jayne with a cigar, but that’s just stereotyping.
Faith, though reformed, is seen smoking in the current canonical comicbook.
