That's actually what I think too, that it was her connection with the Spirit World that protected her, rather than dumb luck as Mard thought. And that is precisely the reason why I came up with this possibly protecting her from mind manipulation. Granted, it's only a very small chance, but I think it's there.

I wonder if Warren, now that he has seven years of training under his belt since he was manipulated pre-trenrou, could now resist this mind manipulation magic if he tried. I doubt he will try it since Makarov was the one to decide it was necessary (maybe even his "last order to his brats" before dying?), but I'd still like to know if he could.
