Wow this episode was really intense! I don't see any repitition in this one(which seems to be your most common mistake when writing) so that's really good!
I also loved the way you built up the deathhere, flashing back to when he was captured, and then bringing it back and making them choose.
Like Wetty, I am oblivious to why they would just stand there, I mean, there are a lot of them; likely enough to rescue Reedtail if they acted fast enough. I mean, I get you're in shock, but doesn't that usually happen right after they die, when you can't move?
The only other thing I may point out is that the title is bothering me a little because venegance is, in theory, anger that stems from the need for revenge. So the title is basically 'angerful anger' f you know what I mean?
