[Steve is trying, but it's a bit much. Then again, he's currently in a video game with people who know him only as a comic book character, and he's traveling around with a Norse god, who he just fended off an alien invasion with after waking up from being frozen in ice for 70 years... So, the Toothfairy is real, he can work with that]

At first, yeah, but I didn't believe Thor and Loki were real until I met them. Even fought along side Thor, so I know he's the real deal. [though not a god in his book still] So other myths are real, it shouldn't surprise me.
