"I met him too, before I found the TARDIS." He should probably look further into who he is and what his intentions are, given his power but honestly, there's a lot of things he should be looking into, and only one of him. Maybe he should get Andrew to split up again to have some extra help. But if the TARDIS likes him, then it's good enough for now.

"Oh, you found it on your first go!" he says as he sees what's inside. "Are you cheating?" he asks with a grin. He's quite fond of this library. Very warm and grand - his whole console room was sort of like this once.
