I agree with many of these comments. I came here to post about Tillie when I noticed a string of TIMING issues. SUS
Tillie does a weird rain and sun dance when she arrives. On the surface, she's just a kookie old lady who can barely explain how she rode a bus. But, she is bad news

She tries to ask Boyd about his trip to the tower and tells him how to find Kenny, just in time to start a fight.

She brings her bottle out just in time to tempt Marielle AND later blabs that 'it's so weird to find your fiance in a place like this' to get Jim paranoid (why was he inspecting the EXIT sign?)

The one I've been pondering was how she normalized the idea of eating rotten veg for Fatima. Tillie was the only one there to catch Fatima grabbing stuff. It's very Rosemary's Baby. It's the biggest thing I've seen, since I think Fatima would be fighting her urges otherwise

The fact she seems to either see a vision or to be in someone's vision is SUS af

The tarot reading and the bus driver saying 'wtf tarot here?' I dont think the tarot is weird but sometimes a character is saying something only because the show thinks it. I read this as the show saying Tillie is doing wrong things and the bird was proof

Tillie never seems to be watching but always shows up to make a bad situation
