On reading all the post I haven't seen anyone mention the picture in Aby's apartment of Any and Alice. MC even mentions that he didn't know they knew eachother. I like Alice but I think she's bad news. Others have made a good case for this, the pic is just another nail in the MC' coffin.
Alice seems under control, but I believe she is good and loves MC.
What I think no one ever mentioned is this: on the last scene, the doctor says "hand over the shard". How the hell does he know MC has the shard?. Even Nora says "now we only need the boy" when she gets the second shard, meaning they still didn't know at that point that the shard was in the world, and they needed the dreamwalker to get it for them.
As far as I know, only Tracy knows MC has the shard. I'm ruling out Marcus because on my play I didn't tell him about the apparition so I guess he doesn't know about it either. Did I miss something?
