Fides,
Interesting theory, no reason it never happened as you describe. Previously I proposed BR manually constricted JonBenet's throat leading to her falling unconcious, via vagus nerve, JR whacking JonBenet on the head, and PR applying the ligature/paintbrush, so to obscure BR's manual constriction, you can see these marks beneath the neat circumferential furrow.
James Kolar thinks JonBenet was assaulted in the kitchen, suggesting PR may not have been present, and might not have been aware of the pineapple snack, which would be consistent with the Ramsey's version of events.
JonBenet likely dressed for bed in her favorite pink barbie nightgown, found later bloodstained in the wine-cellar. The change of underwear must result from JonBenet bleeding, and the Wednesday pair an attempt to be visually consistent with the Day Of The Week? I reckon it was either BR or JR who redressed JonBenet in the size-12's, Patsy would have fetched a size-6 pair from upstairs, knowing full well that the size mattered more than the day of the week!
JonBenet's internal injuries are either staged or part of some pathological behaviour, this aspect is an open question for me, although Kolar offers hints in his book via book purchases by the Paughs.
