My thoughts about episode 2 of season 3 and my predictions for the following episodes.

(spoilers right here… if I’m right, of course!)

The person Maul is talking about at the end (“He lives!!!”) will be Snoke.
But Snoke will only be a ghost and will not look like the Snoke in Episode 7.
Maybe we will not even know his name at all.
At one point he will take possession of Ezra’s body and will be known as Snoke.
So for now I think the theory about Snoke “being” Ezra is true, from a certain point of view.
I would had that it also could be a reason about why Snoke is a CG character. Since Ezra is a CG character maybe they thought it would be logical to also make Snoke CG. (Honestly I think they look alike, kind of.)
I don’t see Rebels finishing with a “simple” death of Ezra. It needs to be something that serves a purpose.
