I don't see Daenerys learning anything. Maybe she sees that she can't do that, but that doesn't keep her from thinking that she still wlil try at some point.

Melisandre IS his worst enemy, even more so than himself. I don't trust that woman as far as I could throw her.

That's why I ship King Stannis with Queen Sansa, 'cos she'd make up for his people skills. ;)
