Back from the break, Sam's slyly passing his trusty EMF reader across a row of lockers, but alas, there are no satisfying VWEEE-YORP!s to be had. Dean emerges from the administrative offices with an update on The Nerd, but we'll skip over that in favor of noting they're both looking unreasonably hot in the costumes they've chosen for their little masquerade this evening. Erm. Well, that, and the fact that the black "ectoplasm" streaming from The Nerd's ear indicates the presence of one very pissed-off ghost, and if I'd remembered anything at all about "No Exit" prior to this point, I would have known a ghost was responsible since the teaser.

Sigh. Turns out Barry slashed his wrists in the same bathroom April used for Taylor's Ultimate Swirlie, and Dean wonders if possessing nerds to slaughter bullies sounds like Barry's M.O. The camera spins slowly in orbit around Darling Sammy's tremendous and tremendously sad head as Sam replies, "Barry had a hard time," and before you know it, we've hit...
