Ogilvy is impressed, mostly because of his own curiosity about the stranger's powers. Illusions are interesting. He has some understanding of those, even if it is a very basic understanding. Prophecy wasn't something he believed in, not before now, anyway. But it is Thor's thunder powers that truly fascinate Ogilvy.

"You...can control the weather." A quick, nervous laugh. "Well, you are Thor. I wouldn't expect anything different."
