"I do," Hermione nodded. "I sort of, felt it, when I found her, as though Riddle’s magic in me recognised the spell in her. I think we’re linked, you know ... all four of us ... almost like an adapted family enchantment. We are all one with the Horcrux. It’s like how you could feel Riddle's other Horcruxes, when you got close to them. If I didn’t know it to be impossible, I’d think you were part of the protections, too. It would be the ultimate defence, really."
