He knows Lilim aren't human, that they're creatures, like witches or wendigo.

But the kid that John's got by the arm, who's pulled as far away from Dean's dad as possible without actually trying to get his arm back, the kid whose eyes don't leave John and are bright with fear, the kid who looks like he hasn't eaten in a couple of days and is obviously favoring his left leg...

This kid looks an awful lot like a person. And what's more, he's the same age Sammy would have been.
