Maybe Snow until she sees June, then she would be off like a hare down to the twins room, if JB grabs her she would lash out and fight.
I would have thought JB would be masked, wearing gloves etc. so the idea of "darling Sheila follow me" is laughable.
Yes,and Adam doesn't seem to realise that June was blocking the door into the bedroom in full view to anyone entering it Rob.
Even if the bedroom light was off,which is unlikely,the hall light would have made June clearly visible to Sheila as she was led in past her.In fact its lucky that they didn't trip over her.
