Keep in mind that Moghedien, Lanfear and Rahvin all had Rands' lovers in helpless situations before; Rahvin even scored a kill before balefire reversed it, while Lanfear had Egwene and Aviendha helpless. Moghedien had Elayne and Nynaeve under her thumb with Compulsion in one meeting.

If not for plot convenience, they would have been dead many times over.
