His left side was against the wall next to the aga.
Where is your evidence that Sheila changed?
His left side was against the wall ? Wasn't it most of his left side which had received the shots and damage ?.
With June,it was mainly her right side where most of the shots were.
Nobody has evidence that Sheila changed,except for her soaked underwear,which I would have assumed that she'd have washed/showered and changed while she was at it.
Not sure that had things been " normal " would there have been blood-soaked underwear left in a bucket for twins to ask questions about though ?
