This was my second favorite Union Dues story so far, behind Off-White Lies. Though I've generally liked them, I like a little action to go with my angst, and having some clear villains, even if they're not super, works much better for me.
I liked this one for its darkness, and how it took a look at an aspect of the Unionverse that we hadn't seen before, a super operating outside of the Union (mostly, at least). The one thing that bothered me was her improbably correct guess about the single cop she sees actually being involved--that would've been much smoother if there had been an actual clue she had seen instead of just randomly following one guy, and he turns out to be the exact lead she needs.
