While most of it is setup for the arc, it was great to see Jason being willing to help people in need for no other reason that being the right thing, that paired with his confidence on Roy's skills, speaks a lot of how much he has changed from his old "lone wolf" ways. Lobdell's acknowledgement of Ducra was also a pleasant surprise (although for some reason people love to get hung up on it)
Roy characterization here is by far my favorite, he never loses his cool and always has a trick under his sleeve to get out of tricky situations.
JD didn't do a lot on this issue but I was surprised by Lobdell actually usinig the plot beats introduced on Catwoman to mold his story, it really feels like Lobdell is turning the page on JD past and preparing her for something else, Lodbell also undid the whole "JD stitched Joker's face over her own" and that alone is a HUGE plus in my book. The Iron Rule guys looks like an interesting bunch and I loved Jason not getting intimadated whatsoever by them, hopefully, they will have a better performance than Underbelly (whom also started interesting and become sort of inconsequential by the end)
Fernandez and Blond keep knocking out of the park on art duties, the splash pages where Jason is swimming and the dwellers in particular are one of the finest job I've seen, if only Fernandez used the featureless helmet (or even better, Medri's costume) it would be my favorite artist to handle Jason.
