The cold and the look from the Librarian is enough to scare Quentin in to never, ever being late about his books ever again. Nope, not ever going to happen.

In fact, he's going to read most of the books in the library, because that way the fingers in his brain don't have an excuse to show up ever again. He also mentions how sorry he is, several times, when he see the Librarian.

He's still going to check the books about The Magician out, mostly so no one else in town sees them.
