Every time the elf makes a logical point, Strange kind of wants to rip his hair out. This cannot be rushed, he says to the person who's style of magic is entirely rushed. I'll need to take this slowly, he says to the person who hasn't taken anything slowly since the dawn of time.

"I'll go get a book then." It's said in a haughty tone of voice, Strange trying to seem like he's still in control and still has the upper hand but he really, really doesn't. So, he swans back off to climb up out of the cellar, trying his hardest (and failing!) not to show how annoyed he truly is.
