Perrin will lead his forces first to rescue Faile then to fight the nearest White Cloak force in the books to come. This is where Galad will come into play. Perhaps Egwene will put a glorious end to the whole "Perrin-White Cloak" mess by making a deal with that pretty boy, Galad, (who will, no doubt, attempt to kill good ol'Perrin). Thus bringing the White Cloaks to Rand and possibly creating animosity between Galad and Gawyne, (since they're both very polar on their views of the White Tower). Or maybe they both can agree that Egwene can be an acceptable intermediate between their two extreme outlooks (We all know that in Jordan's world people who should hate each other can some times magically get along-for no good reason, other than Ta'veren).
