Aye, I agree wit all that, save the last, and like to think those things. What I would have loved and would have made me a tad happier would be us getting a hint of it by show rather than an offhand "working for Torchwood now" comment.

But, for me, Rose had her run. The character was strip-mined and there was nothing new to discover about her or anywhere else for her to go. I definitely think it was the right time for her to go; I'd just have preferred that a slightly bigger hint was given to the audience that she was doing well in her new life.
