Small, random questions about RotE that still bother you (spoilers all RotE books)

[Farseer]

^ still to trawl through old posts re the beautiful woman and crone, as well as take some extra time to think but just a quick question for the day:

Was there a reason why there were not enough heads to match bodies when Kettricken found the remains of Verity's party far up in the Mountains in AQ? Was this just a simple device for RH to disallow verification of numbers to the reader; did it mean that animals found their way into the remains after the attack; that the attackers bore away trophies from their kills OR was there something more? Or nothing?

EDIT: Tsk, see!! I told you it always happens to me! I put another 'up arrow' to refer to the previous post and here I am again, at the top of the next page!
