Thanks to becoming the "impossible girl" she had lived many lifes and died many deaths. Is she going to lose herself literally in the doctor and his world ?. Amy nearly did but she had Rory who eventually led her to chose a "normal" life and death all be it in past New York. Longer Clara travels with him the harder it will be for both of them.
12 will know one way or another he is going to lose her. Just like all the others . He is not suppose to be alone but that is the way it allways ends up. He is a "ageless god" while his companions are mortals. Mortals do what mortals allways do they die. Its just a question of how and when.

And Clara knows this. She has seen the Doctors different faces and lives, experienced his good and bad. But how much of it will she remember when she comes out of his time stream? But she saved the Doctor and the Doctor in turn saved her. This is going to bring them emotionally closer together than most companions due to their shared sacrifice to save each other.

As to being alone, he goes through companions. One leaves, another seems to find themself in the TARDIS after an encounter with the Doctor. He can't help himself, he collects companions like stray animals. Most of the time, just one but sometimes two. He is partial to pretty girls but will pick up a guy now and then when he wants some male bonding (there must be a pub back there in the TARDIS somewhere).

As to his "ageless god" status - I think he would be the last one to ever think of himself as a god with a small or capital G. He would think of himself more of a aging, wandering hobo if anything.

Anyway, my two cents from a new Doctor Who fan from the USA.

Welcome new fan suppose you are right. Hope 12 and Clara have some fun advenatures next year.

Right or wrong, I will enjoy watching the adventures. I think that Jenna and Matt had wonderful chemistry together and I hope that Capaldi works out just as well since the regeneration won't be a shock to Clara if she remembers her time in the time stream.

I think it will be more difficult for The Doctor as I think Trenzalore and the timestream will be the deciding factor and will The Doctor tell Clara the truth, is there something she should know but Clara seems to be indifferent for some reason unless it's her way of coping with her life with The Doctor.

It really depends on what you are talking about. Clara is aware of his past lives, really the only thing is doesn't know at this point is his real name now that she is in the timestream with him at the end of the last episode. She knows that he is worried and even ashamed of the Hurt Doctor.

It is overwhelming for her and she is having difficulty coping with all of the information that she is absorbing but she is tough and will pull through. But will she remember it all after she is pulled from the time stream?

Indifference can be a coping strategy but I think it is more on the line of that she isn't impressed yet. I still think that there was something in the back of her mind that hasn't let her be impressed with the TARDIS and that is why the TARDIS has never liked her.

So while The Doctor and Clara are in the John Hurt's timestream, are the other Claras' helping to save the day while The Doctor is busy

Have you seen that mini episode about Clara and the TARDIS with the multiple Clara's? The one that is every male's fantasy? Including mine Anyway, I would think that the real Doctor and the Real Clara could only be in one place in the time stream at any one time. The others are only memories. But then, the Doctor was able to talk to his memory of the Hurt "Doctor", I guess since it is his memory, he can talk to it. I wonder if Clara could talk to the Doctor's Timestream?
