Right, and taking this into play it also makes her helping in PotW make more sense too. Jackie knows that the Doctor absolutely meant it.

Donna would be an awesome entertainment commentator. (I'd like to think that she would like Brangelina though because they ARE doing good things for the world. Yes, I'm a Brangelina fan. She can diss on Paris all she wants though.) think it would make so much sense with the Donna we knew before the Doctor and what she cared about and the reserves of the biting, sparkling, super-confident, opinionated woman we grew to love as she traveled with him.
