That should be simple enough to find, then. Castiel made the necessary mental note, though he didn't miss the jabbing comment about the lack of non-fiction books.

The bus reached the town and parked itself at the usual spot, near the park. Castiel rose from his seat as soon as the bus came to a stop. While it was all new to Skulduggery, Castiel had adjusted to this routine by now.

While they'd only just met, they clearly had similar goals and a shared willingness to work with others in order to accomplish them. With that, he headed down the aisle of the bus toward the exit.
