Doctor Strange (Spoilers)
Saw Doctor Strange yesterday and really enjoyed it, such a visual spectacle.
One thing I didn't get was the first post-credits scene. It seems like Thor knew Odin was missing and Loki was mascaraeding as him, which happened in Thor: The Dark World.
But when was it revealed for the characters to find out? The only recent Marvel Cinematic Universe movie I missed was Antman, and I doubt it was revealed there.
