Some guy at Geekosity thinks that isn't Doctor Strange. Which is stupid because it connects to Doctor Strange 2 and a Skrull can't use mystical abilities not to mention he was the one who made everyone forget his identity in the first place. I get it this man thought he was acting different, but then again he was different in Ragnarok so I don't understand this.
You know he is Doctor Strange because he is the glue between that film and Doctor Strange 2 and is the one man who can erase what Mysterio did at least I hope he does.
It's Doctor Strange. The same way Wanda was in control of herself, the same way Sharon is just Sharon. Marvel are doing some weird out-of-character things for the sake of the plot at the moment and fans are having to justify it with theories of mind control, deals with devils, Skrulls, but it's just poor writing.
