I'd like to see more of Merlin make his own choices like he did when he let the dragon go free. You know, choices that he makes without having the dragon's voice howling at the back of his head. Like you said it might make him weary of Morgause giving him advice... but I'd like it to be honest advice.
With the Dragon gone, I'm hoping Merlin makes more independent choices, choices that benefit him, choices that he has to learn from himself. But I would like someone there to give advice, and Morgause is the PERFECT person for that.

I certainly think it is these personal reasons that drive Morgause...
Exactly! Her largest leverage that she's revealed/used so far has been Uther!hate, and that works well because her character runs off calculated emotions. *bounces* I WANT MORGAUSE CHARACTER DEVELOPMENT!
