Why the Hell do they keep diminishing the supernatural side of Marvel by saying Asgard's magick is science? Ironically this is right before an episode involving a werewolf, The Frankenstein monster and Dracula!
Having a egotistical blowhard like the Leader not believe in magic is alright with me. Him being a man of science who thinks that magic is hogwash fits for his character. He did get mind-controlled by Dracula even though he felt he was above such a thing.
Though I agree with you about others like Iron Man and Falcon . Considering all that they've encountered and they know Thor and others like him. Falcon is young and being a SHIELD agent he might have believed that way at one time, but as I said considering what he experiences as an Avenger now I don't see why he thinks magic isn't real.
