>>78202881Back in the future Lisa reveals her plan to capture proof that the mirror is haunted, but Bart wants none of it, and tries to convince her that what happened was his fault. They argue, but stop when they notice that all the house plants are dead.
LISA: Bart, look! The plants! They're dead!
BART: Did you water?
LISA: Of course I did! I think so... Come to think of it, I don't remember ever watering them. Don't you see? It's the mirror! It's playing tricks with our minds!
BART: Oh my god. You're crazier than I am.
Lisa rushes off to adjust the cameras. Back in the present Santa's Little Helper and Snowball II have disappeared, and Marge appears unnerved and stressed.
MARGE: Gottafindthedog, gottafeedthekids, gottafindthedog, gottafeedthekids, gottafindthekids, gottafeedthedog, gottafeedthedogtothekids...
Marge realizes she has baked Santa's Little Helper and Snowball into the casserole. She murmurs.
MARGE: Maybe no one will notice.
At dinner Lisa is suspicious of the barely disguised meal. Maggie sucks on Santa's Little Helper's tail, and Homer digs in.
HOMER: Marge, what IS in this?
MARGE: Oh, you know, this and that, dog and cat, heh-heh-heh...
LISA: Bart, I think we're eating the animals!
Bart turns to Lisa as Santa's Little Helper's collar dangles out of his mouth.
BART: Huh?
Marge excuses herself and goes to look in the mirror. She sees herself as a grotesque, rotten, zombie-esque version of herself.
MARGE: Kill the kids? That's a thing to do!
Later that night as the kids are in bed Marge sneaks up the stairs, holding a knife, as she creeps towards the door to Bart's room she's suddenly knocked unconscious by Homer holding a golf club.
HOMER: Well, Marge has clearly gone insane. But I'm not all there in head either. I'm sane enough to realize killing our kids is a bad thing, but still crazy enough to not call the police. How to remedy this situation?
Cut to Marge chained up in the bedroom.
HOMER: That'll do it!
