Just because he didn't use En during his fight with Gon, doesn't mean he doesn't know how to use En. Perhaps he didn't feel the need to train his En? After all, En is just expanding one's aura a ways arround them so they can sense what is happening in that area. Using En doesn't mean you can automatically react to something. You have to train yourself and your En in order to react in that way.

Also, welcome back. I've mainly been keeping the episode discussions going because there's never one when I watch an episode.
