"I wrote everything down," he says, finally. "Gave the book to Tony first. I wrote the details relevant to you in Asgardian."

For a moment, Thor doesn't say anything, but it's somehow apparent from the way he delivered that last word (Asgardian) that he wasn't done talking quite yet. He just needed a moment to order the rest of his words.

"Do whatever you wish with that knowledge."
