Ooo. Yes. I was also chilled when Peter said, "It doesn't matter, because they're not human," after having seen the Shapeshifter who fell in love with his pretend family and didn't want to leave them - they may not be human, and undoubtedly most aren't nice folks, and are plotting this universe's destruction. Still, they are capable of feelings and real "human" emotion, and to see Peter behave that way...yeah. Inner demons, indeed.
