Anyways back to the good stuff, I love what they did with the Cloak of Levitation. Making it sentient added another layer to Doctor Strange, making it really feel like the relic chose him, and added some great levity and chance for gags. When he popped the collar up into the classic rigid formation and it started caressing his cheeks I busted out laughing.[DOUBLEPOST=1478752294,1478752159][/DOUBLEPOST]
The only cameo in that scene is Tony Stark. The scene I am talking about is this one.
Honestly though watching it again like this, it might answer my own question. He says it predicts who will be a threat both now, and in the future, so that sort of answers that question, it just knows at some point Steven Strange could become something more.
