It was good to have that hand to hold again. He'd missed Rose so very much, not just since the Seal had shuffled people through alternate dimensions, but since he had left her on Bad Wolf Bay. Part of him was thankful for the Seal's intervention in his life. It had given him another chance with Rose. Perhaps he should have felt guilty, still wanting her when he had given that chance to his other self, but at the moment, he didn't much care. He was just happy to have her all to himself.
Then, she started apologizing to him.
"What?" The Doctor's confusion was evident in his tone of voice and the furrowing of his brow. "Sorry? Why sorry?" There was no reason for her to be sorry. He ought to be the one apologizing, for what his other self had done, for his nearly dying because of it.
