Sooo David remembers looking up at stars that spoke to him, and his dad could hear them too.
That's what I thought when he was describing that experience. I'm leaning on this being true rather than him literally talking to the stars.
I'd like to mention, and get opinion on, the following:
I stongly suspect that Syd and the group are actually some of his different personalities. I think this because:
1) Back at Clockworks, there is a scene where Syd comes into his room to sleep with him. In that scene, the camera is low to the ground, looking at the door. We see the door open and close, but we don't see anyone walk in. The the camera pans up and Syd is standing over David.
2) David has multiple powers. One is Pyrokinesis. At he end of episode one, a pyrokinesis type ability is used when he gies under the swimming pool by...Kerry, I believe?
3) We see a guy use telekinesis, something David is also capable off. Ptolomy uses a form of telepathy and i'm assuming Bird also uses telepathy? Both abilities that David should be able to command.
4) At the end of episode one, there is the scene when David and Bird clasp hands, we got a show of the group arrayed around Bird, facing David. It is my supposition that this shot framing reflects David coming face to face with some of his disparate personalities, and finally taking the first (maybe subconscious) step in acknowledging them and his different abilities.
I'm sure there's tons of stuff I've missed, but I can't shake this feeling that most if not all of the group are not actually there, and we're seeing this being played out in his head. I think the government division is real, but there too I'm wondering how much we're witnessing from David's lens. That's on the basis that not all his personalities have to be 'good'.
Really great show, i think they did a fantastic job on this.
