What's in sarah?
I think the experiment/evil/bob? is in sarah now. The experiment has escaped the glassbox in the beginning. It is on our earth now, sarah felt something was gonna happen with her..in the supermarket in fear " something is happening with me". It scares me that the firemen said " its in our home now" . So eventually evil wins? Or Cooper, laura, Andy,the bookhouse boys and the glove man come with a magic trick in the end?
I think in space this whole story happened already, when you've been in space you know the outcome.Carl Rodd and Margareth been there too, they know what big is happening out of earth (or know/feel it in some kind of way). If you're not remembering the outcome,it slighty comes back to you in dreams(just like cole, cooper, Sarah? etc.)..because you've been there and in the end you know everything because it's happening that way 🙂
Since episode 8, I've thought "Laura" would appear as a spirit rather than in human form. I compared the teeth in Sarah with Laura/Sheryl Lee's teeth and they are very similar (there are minor differences with the incisors which are better aligned in many photos of Sheryl but they are very close).
I believe the only entity we have seen possess people is Bob (Mike may be able to but his human form looks exactly like his lodge form, so he may be a different entity). We know that bubble-Laura had a similar initial structure to bubble-Bob, so could assume she has similar properties/abilities.
So, I think it is equally likely that it is either Laura's spirit or Mother that possesses Sarah.
I agree with you Jasmijn. The mother is inside her
I hope that's not it. The Mother (experiment) seems to big, to much,to be embodied. It would be like having Sauron walking around (and yes, my geeks, I know that in the days of Numenor Sauron wore a beautiful visage, and was embodied until he lost the ring).
BOB, maybe. We didn't see Sarah's odd behavior until after part 8, did we?
I AM the FBI.
Sarah isn't necessarily possessed by an evil force and I do not assume that allies of the Fireman will be "good" in the usual sense. It would not be surprising for either Sarah or Laura to attack the trucker based on their histories with middle age male predators, so I wouldn't be shocked if it was the Laura-spirit.
I think Laura-spirit is in Sarah and together they will have an epic showdown with Bob and whoever he is with when the time comes.
I agree with MJ about Mother - that would be too much and we've seen no suggestion that Mother could or would want/need to inhabit a human.
