ok so in the beginning of "the name o the Doctor" we see her on Gallifrey with the first Doctor AND Susan, and right away my mind went: "wait. if she is on Gallifrey, would that make her a timelord (timelady whatever wewe like i guess)??
it says she dies saving the Doctor every time, butif she dies wouldnt she just regenerate? but what would happen then? that clone of her wouldnt have any purpose then right? would it die? au would it forget? could that clone possibly be another companion in the future and leaves? i am very curious and confuzzeled kwa this, your thoughts?
