And to be quite, well, frank, I didn't see that ending coming. I don't think anyone realized he was going after Hydra, though. So the dynamics changed at the end.
The first part of this comic is Iron Punisher going after Baron Zemo, and the rest is Zemo vs. Punisher vs. Avengers (or former Avengers.)
Anyway, it was a fun time all around. Although I have one question: why does Castle know Hunger Games but not Star Wars?
