No one has EVER said she slept with June AND Nevill. The premiss is that she slept in the main bedroom with June to be next to the boys room. Nevill slept in the other room because that's were the slippers were and his blood was found outside of Sheila's room but NOT in the main bedroom. Had he been shot 4 times in the main bedroom, his blood would surely have been in there - it wasn't!
So you can stop suggesting that Sheila slept with both Nevill and June because it's now been fully explained!!
Neville's blood wouldn't be found in the main bedroom. He was already on the move when being shot at. So not enough time for any blood to drip down.
So Sheila slept in the main bedroom, in bed with June. So she could be a few feet nearer two six year old boys.
It was inconclusive whose slippers they were. Thread already created.
As I said when Lookout said Bamber wouldn't commit the massacre in case the windows had just been painted, 'you couldn't make it up'.
