Jack winked at Rose as they entered the TARDIS library. "Did it work?" she whispered cautiously, glancing around as if she expected a monster to jump out from between the shelves at any moment.
"Yeah. I'm Jack Harkness, what did you expect?" the Captain replied confidently, leading the way between the towering shelves of books. The library was one of the biggest rooms in the TARDIS.

Rose grinned mischievously. "Oh, Captain Harkness, I will."
