So on SRK, someone said Gill, Mysterio or Dr. Strange please and Master Chibi said "Yes~". Then dude said "Wait Wait Wait...OMG can you tell me if ONE of them is confirmed? Gill, Mysterio or Dr. Strange" and Master Chibi said "Yes~." What have we got here?
Also, according to him, this tweet:
was deconfirming a character guess. Question is, which one? Someone suggested Cyclops or Pyslocke and he responded by saying "Warm enough that I can feel it in my BLOOD." So I'm guessing Cable is deconfirmed (Cyclops' blood)?
tl;dr One of Mysterio, Gill or Dr. Strange is in apparently. Cable possibly deconfirmed.
