Interesting. Speaking as someone unfamiliar with the canon, it seems to me that at least part of the reason she did it was to keep this cyclical momentum going. The last line, at least, hints at that. However selfish this decision is, there's incentive for her if she gets to see him again, in this future he tells her of. She hasn't thought far enough ahead to recognize that she'll regret these actions when that next meeting occurs, only that it will.

Very nice! =)
