Jack doesn't chase so much as... wander. He's a book lover, that much isn't news to anybody that's known him for longer than five minutes. Istredd's tower is like Candyland, and he's been content to wander the shelves for the majority of the get-together. Istredd steps out for his breather, Jack spots him and unobtrusively makes his way over.

"Hey." A quiet, polite greeting while he gently folds the book in his hands closed around one of his fingers, acting as a bookmark. "Good job on your whole... speech thing. I um- I wanted to ask you a question. If that's cool."
