"Hmm? What? Oh! Oh. Yes. I suppose I might." The Doctor reached up to rub the back of his neck, suddenly sheepish at his oversight. "Sorry. Didn't think ... Well. I should have, really. She's a bit different from what you're used to, isn't she?" She must have been. He'd been holding back the regeneration for so long, fighting it so hard, that he suspcected when it did finally happen, the energies involved were immense and rather violent. Add to that Amy's clear unfamiliarity with the ship, and the Doctor had a decent picture of what his regeneration should have been like, if it had gone to completion this time. Unless of course he was wrong, and he hadn't been meant to become his eleventh self just then, though he doubted that was the case.
"Come on then. Let's have a look at what the old girl's come up with." He led the way into the main hall and took a few turns before they came up on a section of the TARDIS devoted to living quarters. He bypassed the doors that belonged to Rose, Donna and Martha and a few extra ones besides before he came up on a room that was sitting open. "I do believe she wants you to have a peek at this one," he noted casually. A quick glance inside showed him a room that was a bit out of synch with the rest of the TARDIS's layout, and he suspected she might have been able to tap into the future to recreate a bedroom more in keeping with what Amy had known.
