We know that Charley's time with Six is going to come to an end next year. They already expanded the number of audios once and I'm personally doubtful that they'd do that again. And really she can only go on lying to him for so long and once he knows there's no way he'll let her stay on. So my question is this: How is Charley going to leave?
It's an interesting question. She almost left once. ( spoilers for Absolution and The Girl That Never WasCollapse )
So then in Brotherhood of the Daleks ( spoilersCollapse )
Of course once Six finds out there's no way he'll keep her on. It's too dangerous to the Web of Time. Which Charley knows.
So really what is going to happen to Charley? How are they going to write her out? I can't help but feel that they've backed themselves into a similar corner that Rose and Donna were backed into. The 'I want to stay forever' corner. Will they do it well or not? Is it going to be a sudden marriage? Charley is a bit of a romantic. Will she find a new place to call home? It's not like she can actually go home.
Personally I'd like her to go off and be space pirates with Mel, but I doubt that's going to happen.
What does everyone else think? How do you think Charley is going to leave?
