The moving door always baffles them. How did it move 3 times >@@(*&)
Well, sadie has rejoined 'real life' briefly, so we'll have to guess
I suppose 'the lifter' first opened the bedroom door when he went into the childrens' bedroom to drug them
That's when Gerry comes in and spots that the door is open too far
'The lifter' successfully hides behind the bedroom door whilst Gerry makes his check in the room
Gerry goes out and 'the lifter' leaves his hiding place and goes about chloroforming the already sleeping children
Then he raises the shutters and opens the window in readiness for 'the carrier' ... who has been signalled by 'the watcher' that the coast is clear ( although he is mistaken because Gerry and Jez are still there standing in that 'blind-spot' in the street )
'The carrier' arrives, having been wrongly signalled by 'the watcher's' lighter, and 'the lifter' passes Madeleine through the window ... I might be wrong there though, because sometimes sadie says the window was only opened so 'the carrier' could offer
encouragment to 'the lifter'
Anyway, at that point, 'the lifter' leaves the apartment by way of the front door, to which he has aquired a key ... and that explains the
second time the bedroom door was opened ( gerry having pulled it back to being only slightly ajar on his check )
'The lifter' leaves the apartment ( never to be seen again ) whilst 'the carrier', having been abandoned by 'the watcher' , who had been scared off by the sight of Jane, Gerry, and Wilkins all being there in the street ( not much of a 'watcher' was he ? ) is left to make his way on foot with a drugged Madeleine in his arms
That's when Jane Tanner spots him ... because 'the carrier', you see, is much bolder than the car driving 'watcher', and he chooses to walk straight across the street without even peeping round the corner to see if the coast is clear
So back to the bedroom door you asked about
It was opened for a second time time when 'the lifter' exited the bedroom
And that's how Matthew Oldield found it when he checked at 9.30pm ... open wide enough for him to look into the room
He left it like that, and Kate found it the same way when she returned to the apartment at 10pm
I think that about sums up 'sadie's theory'
It goes on a bit after that ... 'the carrier' hiding with Madeleine in the staff quarters for over half an hour ( for some reason or another ) before emerging again at just about the time Madeleine was found missing to make his way towards the beach ( for some reason or another ) ... where he was spotted by the Smiths
From then on it goes deeper and deeper into the realms of fantasy and is just not worth repeating
