"I felt a bit lost, you know," Arthur interrupts him, "when I first woke up here without you. Panicking, I suppose. Ah-- there you are."

His hands have found John's arms, and travel up to his shoulders, as he marvels at-- well. John achieving exactly what he wanted: his own body, the final step of their separation. It's amazing, really, how that's worked out after everything. Suddenly, unexpectedly, and perfectly -- for one of them.

"God, you really-- you really are standing here."

Arthur moves closer, his left hand light on John's shoulder, his right rubbing his own face in amazement.

"Oh, and--" He laughs again, very quietly, and pats John's shoulder. "Oh, you're... you're about my height."

That makes this a lot easier, then. Arthur brings up his knee very quickly into John's groin, and his right fist just as quickly up into his stomach.
