Watching “Waters of Mars” and feeling very melancholy… ohhh poor Ten. His character arc just kills me. He’s just so had it and it’s so flippin’ heartbreaking.
Edited to add: The way he was acting there at the end with Adelaide… I have this feeling that had she not taken it upon herself to shoot herself in that moment that the Doctor would have been knocking down the barrier between parallel worlds to get Rose back. He was flashing back to a lot of things he said to and about Rose before returning to the Mars base, telling Rose that he was the last of the Time Lords, explaining about the barrier between the universes and how he lost her and I think the whole thing with Rose was VERY much on his mind during all of this. And while, yes, I am a bigtime Ten/Rose shipper, that would have been HORRIBLE. Not only putting the multi-verse in danger, but he wouldn’t have given two flips about poor Tentoo and Rose would have been horrified and OMG can you even imagine? I get teary just thinking about it.
