So basically everything that happened so far was completely redundant... what was the point in any of that if it was just going to end up with a "yeah... go do what you want." when before it was "I'm going to kill Gon, because you may never have friends!". I mean the series is decent so far, but I sure hope at some point Gon actually becomes somebody who actually does shit rather than simply talk.
This little fiasco of getting through the wall and training to open the door was pointless too... seeing as they had nothing to do with his father's resolution.
