TO me, magical is just a side effect or how they kind of throw you off a bit. Doc Strange is suppose to play a huge role in Phase 3 and suppose to replace IronMan/Stark as the main cog for the Avengers so he is likely not going to make an appearance either.
Every time he speaks of Tahiti it reminds of the movie The Island. I could actually see it being Forge since he is a sorcerer and part machine and I think he resides or have an island headquarters too.
But wouldn't Forge be under the X-Men umbrella that Fox has control of or does it not matter since this is on television? That would be cool if he was an LMD.
