Well, before we despair of the collapse of Western civilization (or at least "Lost" ), let us remember it's just one episode, and maybe she has only a few lines, or even better it's like Libby's "return" and A-L shows up in a dream sequence and that's it.

Cynthia Watros' return was much heralded and then folks were bummed because that's all it was. Maybe we can hope for the same for M-Rod.
