@LouWohl I think we've firmly established at this point that Birdy's cunning wit isn't why they hired her so much as her ability to turn every problem into a nail that needs hammering.
Honestly, this was the perfect way to end it. I never expected major arcs and blossoming romance and character growth from this thing. It was always about trash people acting like fools. The implication of development on the final page is great.
