But in general， take my advice， when you meet anything that‘s going to be human and isn’t yet， or used to be human once and isn‘t now， or ought to be human and isn’t， you keep your eyes on it and feel for your hatchet. And that‘s why the Witch is always on the lookout for any humans in Narnia. She’s been watching for you this many a year， and if she knew there were four of you she‘d be more dangerous still.”
