Oliver opens the door and sees Oliver? and a woman. The not Oliver spots the real Oliver and picks her up.
"Is this your daughter?" He says to the woman.
"Oh yes! Kyleigh what have I told you about running off?" the woman takes hold of her and frowns, "and where's your diaper?"
Oliver, now Kyleigh, now pieces it together. The dress must have belonged to Kyleigh so Oliver became Kyleigh and Kyleigh became Oliver. Figuring that out doesn't help as she's carried away from the fitting rooms, where she sees the ring sitting next to some discarded clothes.
A different kind of change follows, as she is laid down next to a stroller while her new mommy tapes a diaper around her waist. She's then buckled into the stroller and rolled towards the children's section. She tries to undo the buckle, but lacks the motor skill to do so.
