Nice,

haven't relistened, do not recall.

But, I think it says more about Pegs than the biters. Remember, it is Peg's dream. She has the shock of killing Latch as well as TOWTM imitating Paul and probably heard horror stories the arena. Of course, you can embrace the dark side of Pegs, like I do. Burt puts two in its chest and she tells him that it is not enough, shoot him again...
