Harrow stepping up and going mental was something I've been waiting for in this show, and they delivered on that front. I would've liked to have seen Nucky take down Gyp but it was still satisfying. The body count was massive.
The twist with Luckys arrest was pretty cool and I loved the set up, so to speak, with Rothstein for next season.
I hope we start to see the rise of Capone next season. Stephen Graham kills it with his performance.
