Once again, WackyWoof lives up to his name! I know you had this on the "No Chill" meter, so thankfully, I bore that in mind when reading this one, and it was certainly a trip! I often get quite invested in the characters in stories of this nature when they have been so broken and oppressed, and wasn't too surprised by the wolf's reaction at the end, especially with the side comments made earlier in the story. The juxtaposition was a bit jarring, but I believe that was also the intent.
I like that it didn't try to sanitize everything or make a "happily ever after" ending. I like that all the characters had flagrant flaws on display, and that there was no "good guy," yet you still, against all odds, find yourself pulling for the xenophobic otter and his vigilante wolf. (Again, not endorsing EITHER of their actions, but great job in helping us understand their motivation.) And it all still fits within the context of the WackyVerse without necessarily needing a direct connection to your other works.
