Somebody can't count. The tigerwolf was chasing 5 wolves, and caught one. Then the four remaining ones attacked it. It swiped them to the side and they continued to run at the caravan. That was last chapter. This chapter, one group is dealing with 2 wolves, and the other 3. But one is dead. So where did this fifth wolf come from? And that was before the new batch arrived. Which, since they weren't being chased, should have just escaped without notice.
