Reading this made me cry all over again, but in a more hopeful way this time. Thank you SO MUCH for pointing out that Rose and Ten II interacted before they were dumped on the beach together. That's been one of my biggest problems with it - I wanted to see them flirting earlier. I wanted to see her recognition that hey, this guy is the Doctor TOO.

The picture you posted helps, somewhat. :)

Whatever else happens, he had this one last day

And I think from the moment he saw Doctor II, he KNEW. When I can finally bring myself to re-watch, I think awareness of that will hurt even more.
