Recent rumors and theories surrounding a plot point in Marvel's the Avengers centers around long-time Avenger Scarlet Witch being depicted as a cellist. I have been trying to find the specific reference, but with no luck. Where does all this business about Scarlet Witch being a cellist originate?
And for clarification, the rumor I am referencing is:
Agent Phil Coulson is killed by Loki. After his death, Nick Fury calls him his "one good eye," which could either be a turn of phrase referencing his eye patch, OR a nod to his vision which in turn is a nod to long-time Avenger The Vision. The theory is that Coulson's brain patterns will be mapped onto a synthezoid (fancy word for android) body. Other references that support this are that Coulson mentions dating a cellist, which apparently is a reference to the Vision's wife, Scarlet Witch. Also the Vision's synthezoid body comes from the 1940s Human Torch, which was glimpsed briefly in the Captain America film. And lastly, Tony Stark mentions "Life Model Decoys" in the film, which establishes that the technology to create artificial intelligence and androids has to either already exist or is plausible. Or it's a joke he's making, but even so, it's still a reference.
