Whoa there, Togashi really needs to slow down the pace a bit. I feel like there could have easily been a chapter inbetween the last and this one, in which Gon and Killua join up and talk a bit (Gon did say he really wanted to apologize to Killua a couple of chapters ago, after all), Gon meets Alluka, they part ways with Leorio and look up the World Tree.
The way things are rushed really makes me wonder whether Togashi still cares about properly developing the story and/or ending it in a befitting manner instead of pulling another YYH.
Also, I hope we'll get to see Kurapika soon. Leorio has been kind of shot into oblivion again these past two chapters again, so I hope he has actually gone trying to track Kurapika down or something.
