It's very difficult to leave Gabriel at a loss for words, but the TARDIS seems to have managed it, at least for a few moments. It's difficult to reconcile the ideas she just put in his head with his concern over her apparently very unstable state. He wants to offer to coax her open and be as rough as she wants him to be, but this isn't the right TARDIS to give that offer to, and not the one he'd want to accept.

He takes her hands in his own, pulling them away from his shirt. "You're ten pounds of awesome in a five point bag is why. It doesn't all fit, so you're spilling over."
