Given most of the continuity in the show (they really do a nice job of being consistent), I doubt the writers have forgotten about her. I think it more likely that, just like other characters, the actress has had other things, and so is not able to get away for an extended arc.

We know she is back for 4x12. (at least she is listed in the press release). I'm hoping that she will be back for more than just that one episode.

As for the rest of it, I agree that there's a lot more to BF/MS than is seen with the naked eye. But what her motives and agenda are have not been revealed, at least not yet.
