10 confusing sciency stuff, I don't try to understand
well in the general hustle and bustle of the episode (won't try to explain the whole plot) Jenny points out that the Doctor acts quite a lot like a soldier himself, with all his planning and strategies and everything. He accepts her and plans to take her with him when they leave. Then after the Doctor saves the day the general from one of the armies (nasty guy) tries to shoot the Doctor and Jenny protects him. Despite the fact that she has two hearts there is no sign of regeneration so the Doctor, Donna and Martha go back to earth but at the end of the episode it turns out that Jenny is alive and she goes flying off in a spaceship. Admittedly it's not as sad as it would be if she hadn't lived but it's still sad that he doesn't know she's alive
