"Well, the Sea is the sea, of course," Lydia said, "and Wormentongue is currently bound." That wasn't true any more, but it was true when she was from so she was just pretending, okay? "And before he was bound he was mostly stuck in a particular patch of Hertfordshire, where I'm from, though he did leave it at least twice, and also he wasn't alive at the time so I'm not sure the usual rules applied to him. He wanted to eat me and Kitty, or else Miss Lambe--I suppose ideally all three--so he could become alive again."

Welcome to the wonderful world of Lydia Bennet explaining things, Adrian!
