I've already answered that several times both here and on the blue forum. However, June relayed to Pam how she was worried about Sheila because she was seemingly very withdrawn.
1. PERHAPS given her condition, June (or indeed Nevill) might have suggested that she not be left alone. Given that the twins were sleeping nearer to the main bedroom.
2.PERHAPS she wanted to stay there for easier access if they woke (perhaps they had woken over the few days of the visit).
3. PERHAPS, given that Nevill was late to bed that night (because Jeremy left him to finish the rape harvest), he suggested the swap.
There are many plausible reasons why such a swap might have occurred. The fact that they didn't always get on is neither here nor there - given that she had 'chosen' to stay with her parents for the week - this proves that they could stand being in the same room without ripping each others hair out!!
1. As I've previously stated the Bambers didn't seem unduly concerned about SC's state when FE phoned asking them/NB to come straight away. They declined until the following day. This was when her condition was such doctors were called to sedate her. So I dont see why they would be so concerned about SC when she was under their roof that they felt it was appropriate for SC to sleep with June.
2. JB's room is more or less opposite the twins room. If SC felt she needed to be closer to the twins, or vice-versa, she could have slept there? There's a box room between the main bedroom and the twins bedroom with two connecting doors. Do you know if the doors were open or closed?
http://miscarriageofjustice.co/index.php?topic=633.msg25947#msg25947CAL's book mentions the twins sleeping at SC's best friend's house without either parent present and they were fine. So I'm sure they were fine to have their own bedroom at their grandparents home with their mother sleeping in a nearby bedroom.
3. Perhaps NB was late to bed but I'm not sure that would lend itself to SC sleeping with June and NB sleeping in SC's bed. Was SC's bedding forensically analysed? If NB slept there no doubt a hair or two of his would have been on the pillow.
I guess SC went to WHF to visit others not just June eg NB and JB. Perhaps she liked seeing the extended family too. She telephoned Betty Howie's daughter ?, Sarah I believe, to arrange to meet her. Regardless of SC's relationship with June, which I think was poor and wouldn't lend to her wanting to share a bed with June, it's so not the norm for adult children to share beds with parents unless circumstances dictate eg lack of bed elsewhere.
