Oh, I'm so worried about them! But this is such a perfect portrait of their relationship, and all its depth of meaning:

" ... but hugging Rose ordered his universe. Together, they bent space and time. The temporal eddies that had always swirled around him became tranquil pools when Rose took him in her arms."

And then they have a real, grown-up conversation about all that has happened. Well, most of it. Wonderful, quite wonderful.

I'm intrigued by the idea that Donna will recover her memories of him now. Hadn't thought of that possibility. What will happen to her, trapped in the other world with Shaun and no Doctor?
