When Miles is grabbed by the shoulder and yanked by something with superhuman strength, he lets out a choked cry - Walker's found him, he's going to tear his goddamned head off!

But there's no snapping and crunching of bones, no pain, and Miles peeks through the fingers he has left at the man in front of him. He tries to breathe - can't - then manages to get a few short, sharp ones in. His heart's going like a rabbit's.

"How do you know?" he asks, knowing it's a stupid question but neurotically having to ask.
