I think you hit the heart of the problem for both of them in the relationship, whatever it may be. So far we have seen the Doctor not even know her, mistrust her and finally befriend her and rely on her. Now as he goes forward into her past... are we going to see the same range from her? Is there a time coming soon where he will have to gain her trust and friendship?
OT: I'm still so happy to finally join and meet other people that will talk about this at length! *happy dance*
I also find her a little annoying. Maybe its because at some points she is actually cleverer than the Doctor. I mean, nobody is suposed to be smarter than he is, and it feels totally wrong to see him one step behind. The first time we saw her was with Tennant, and the whole thing didn't really make sense to me then...
Another point is, seeing as she is supossed to be getting younger, while he gets older will we have to all the way to when she was born, and even beyond? How on earth is that going to work??
Yeah, when that occured to me it made me think "Uhm, twilighty?" and then shiver...But I'm gonna hope that the doctor isn't going to have to spend time being in love with a 7 year old girl or something... Cos that would be creepy and wrong on SO many levels!
But me and my friend have a theory that The Doctor won't spend any time at all with her while she's small and growing up. I think he'll leave Amy and Rory someplace once he finds their baby, and that then he'll just pop in on them every now and again until River is old enough to A) Travel about with him and B) Fall in love with him.
I want the Doctor and River to be together, but just when it's reasonable you know?
I liked how she seemed to know more than the Doctor. Maybe that's just cos she's a girl and I'm all for equality and by that I mean girls proving that they can do anything a man can do and better. Feminism FTW. It was a bit weird but I still like her!
