Thinky thoughts.
I'm still not sure what exactly the point was of this episode or Jenny's creation. I mean, it was like some strange fan fic to be spun off into a series of "originals". If she had died for real it would have been one thing, but why did she live and take off on her own? It just really didn't make any sense to me.
Also, I think after this season if they don't keep Donna and Rose isn't back back, I probably won't continue to watch. Because, I'm sorry, but relationships (romantic, in particular, but really good friendship stories, too) are what anchors me to a show, and Martha tested my patience enough. I really didn't like her, and the Doctor himself and his holding onto Rose was really what got me through that.
If something terrible happens to Rose or the Doctor loses her again, I'm just not going to want to watch anymore, really. I might, if I don't have anything else to do, but despite how entertaining David Tennant is, I don't think I can go through that again. I understand if Rose isn't immortal they can't be together for literally forever, but she's young enough that she could be with him for a lot longer. If they just tease us with that and take her away again, I can't imagine how I'm going to feel, and it's going to be incredibly difficult not to read spoilers and find out beforehand.
I almost wish she wasn't coming back (if it's not for longer), because Doomsday is soul-crushing enough without having to endure it again. Because even if they're reunited and they're kind of able to make peace with a previous departure that was all too sudden, it's still not going to be satisfying. They love each other and the Doctor has been miserable without her, and I'm really tired of him being miserable. How would it be any easier to get over her the second time around?
It was just like when Jenny was "killed", I wasn't particularly taken with the character (though I did think she looked like she could be the Doctor and Rose's daughter, *g*), but I was sitting there, kind of enraged, going "STOP TORTURING THE DOCTOR!!!!!!!!!" Because it's just like bad things constantly happen to him, no matter how hard he tries.
So basically I'm just saying if they keep breaking my, and his, heart, I don't know if I can keep going with it. I like to watch things that don't make me miserable. At least, not forever.
