i've heared loads of rumours but like hearmerlin2 said i don't think any have been comfirmed. If nimeuh did return in S.3 i think they would show something about it in the series 3 trailer, but they didn't :\...i think it's mais likely that she'll return in series 4 (please say there is one!!) but i really want her to come back!! and if she did i think it would be a really amazing and complicated thing to happen, and a great idea, so hopefuly the producers will put michelle Ryan back in. Sorry nimone :\ i really want her to come back and cadastrar-se morgause and morgana in an evil plot! you should find out soon enough, only time will tell.....lol xx
