Phew, Janet killed the serial killer. Just in time for Halloween! She smiles at the costumed kids.
Except that one isn’t a kid! He’s the serial killer! Janet stabs him desperately.
Janet explains everything to a policewoman.
“Sounds pretty frightening,” says the policewoman, and looks up. It’s not a policewoman! It’s her best friend who got killed by the serial killer and now she’s a zombie!
Janet wakes up! It was all a hallucinogenic episode. Phew.
Except it’s not and the serial killer kills her!
Oh man! The surprise fourth ending! You could never see it coming!
Because of Halloweeeen!
