Well for Skolas' kill we don't have a ketch since the Queen already took them to the house of wolves to give us a simple ship. But Taniks and Draksis' ketch should totally be ours i mean we killed them and their best soldiers they should even follow us after all that's what the wolves did with the queen, they follow her orders only because there's no other kell so why not us, the house of winter doesn't have any important fallen left make them be in our command and be in our ketch since we can pretend to the totle of new kell as we killed the precedent one.
