Well, Mithian's already come back once, in Another's Sorrow. Which was good. BUT there's still a rumour going around that she's in more than one episode of season 5. So I guess we won't know for sure till the end of the season.

But I agree with you: Enough is Enough! And I really hope the writers won't do it.
