Amazing chapter. This isn't what most of us thought the reunion of Gon and Ging to be like, but that's what makes it so good. Instead of being this epic meeting, it's mainly just awkward and comedic. Still, Ging does try to help Gon, which is nice. But really, the best thing about the meeting is the audience. Their reactions are hilarious and I think a lot of readers reacted the same way.
From what I understand from the Viz translation, Ging says that Kite will kick Gon's ass again if he apologises wrong. This must mean that Kite told Ging about how he punched Gon way back in chapter 1. It's a nice callback.
