In my rewatch of episode One, I realized that the Bess is standing in the spot where Adam was when he drank. Given julian's seemingly calm demeanor until Bess starts choking, I'm wondering now if Bess drank from Adam's cup as well as her own, and the kid was not expecting her to be affected because both mugs weren't poisoned.
Despite Julian's claims over the various episodes that lying is not ok, when Ambrose asks him "To your parents?" (in response to Julian saying "I gave it to them") Julian answers "Yes", after much hesitation. He knows that Bess and Adam aren't his parents (doesn't he?) so either he is lying when he says he gave it to them, lying when he claims he gave it to his parents, KNOWS he is lying, or is it possible that Julian gave the Jimson weed tea to some other people he thought to be his parents at some other point in time? Could HE have killed the Beacon and/or Marin?
We see the hooded figure as an adult, but perhaps that's because Julian sees the figure that way. Could the figure be Shadow Julian?
Jack calls out "hey Jean, here's the Keller old boy I was talking about..." to someone walking down the street with a dog, but Jean is the woman at the restaurant and I'm pretty sure the person walking down the street is a man (in the closed captioning, it is spelled Jean, not Gene). Originally, I got the impression from Ep 1 that Jack was in early dementia stages. He "remembers" an explosion that Ambrose doesn't from school days. He remembers something else that Heather corrects him and says "Dad, that never happened". Also Heather seems to be doing basic shopping for him and reminds him he is almost out of this or that.
We get several good looks at a painting in the motel room of a lake. Could it be Purple Lake?
