At the end of season 1, Rose looks into the Time Vortex and is able to see and manipulate things throughout all of space and time. Why did she not foresee and save herself from her separation from the Doctor at the end of season 2?
For extra points: Why did she not stop a whole slew of other things, like the Cybermen and Dalek invasions at the end of season 2?
Possible explanation 1: Rose isn't really in control of her time sense. She's overwhelmed by it. She can see everything, but that means she can't really see individual events with any clarity, and she certainly isn't coherent enough to take specific actions or safeguards against them.
Possible explanation 2: See this quote from The Parting of the Ways (s01e13):
Rose: I can see everything. All that is. All that was. All that ever could be.
The Doctor: That's what I see, all the time. And doesn't it drive you mad?
If you ask that question about Rose, shouldn't you have to ask it about the Doctor as well? But I don't think anyone claims that the Doctor can see all of creation, from start to finish, all history and all future. Just times and places he's been to, but he's got a sense for time, for when he is and what comes next, what is a fixed point in time and what isn't. That might be what Rose can sense when she is inhabited by the time vortex.
Certain-but-boring explanation 1: Russel T. Davies hadn't written those events yet. :)
Given the fact that where she ends up is "Bad Wolf Bay", it is tough to argue that she did not foresee, or possibly even cause the events that led to her separation.
In the present time, she was heartbroken by her separation, but in the long run she lives happily ever after with her Doctor-clone. It is perfectly reasonable to suspect that Rose saw this as a possible outcome, and determined that this was the most favorable of all of them.
As much as a physical god she was at the time, her body was still dying in linear time. Even when she destroyed the Daleks, she scattered their atoms in seconds (practically an eternity), she didn't scrub them out of all of space and time, causing a paradox. She was powerful, but not omnipotent.
Besides, she was busy fixing the past, helping the doctor avoid the worst thing he ever had to do
The Doctor : There is fixed points in time.
So, we can ask ourselves how The Doctor knows which point is fixed and which is not.
While she was looking into the heart of the Tardis, Rose saw what the Doctor sees, so she was as aware of this fact as him.
Think about what could happened if Rose saved herself to disappearing from this universe: the Doctor would surely stay with her as long as possible. So he would probably not meet his other companions, especially not Amy.
No Amy to... have fun in the Tardis, no River. No River, no Doctor, 'cause he would probably died in "The name of the Doctor", killed at the door of his tomb.
So, in my mind, Rose was aware that she was going to disappear. But she has also conscious that she can't do anything against it without destroying the Universe.
She was written out of the show, she quit. So that is how the director takes a character out of a show when they decide to leave....... If you have watched the show (the mentalist) and seen the episode (nothing gold can stay) you would know this 😐
