Tell "Katie" about this feeling

You -- in body and mostly in mind now your little sister Claire -- and your girlfriend Jessica similarly transformed into her little sister Katie are about a block from your house now. "Katie, I'm Claire!" you tell her.

"Yeah, and I'm Katie. So?"

"That last zap... I feel I'm supposed to be Claire and never be David again!"

"I was hoping you'd feel that way," she says, stopping. "'Cause I'm Katie now and Jessica is, like, totally history. I guess Dave and Jess just eloped and vanished!"

"Doesn't that bother you, that you're Katie instead of Jess and I'm Claire instead of Dave?"

"It's how things are supposed to be," says Katie, starting to walk on towards your house again.
