If Dick knew what was going on, I think he would rue the day he told her that. (I'm glad I'm not the only one who thought of that when it became clear that M'gann was going down the wrong path.) It wouldn't surprise me at all if M'gann has been altering the memories of other Team and League members. Connor could sense what she was trying to do, but their minds have 'melded' as he put it. It knows her in a way we probably can't imagine, whereas others don't.

I have a feeling that when Dick first had the idea to put the plan in motion, Connor and M'gann had just recently broken up. Connor wouldn't trust her, and I imagine he was hostile to her to an extent. They would not have been in a healthy enough place psycologically for this sort of mission. M'gann's shape-shifting ability is very useful for this kind of mission, if Terrors is any indication.
