This fucking fight right here.
http://www.youtube.com/watch?v=CW_fephDr5AThat last line... at the end of the fight...
"My friends got hurt... that's what a poke'mon battle is."
Every pokemon he used came from chargestone cave (or around it). It had confounded me, but that battle, and that line, made it all clear.
I heard that line, and then I realized he'd caught them, there, in that cave, just to fight me, to prove to me how very little is gained through these fights.
It hurt me in ways I've never explored, and at the end of the game, when the professor asked if I was glad I went on this journey, I answered honestly.
'No.'
After everything N had said... I just felt unclean. I felt... wrong.
But then I found out his full name and laughed like a little bitch before chucking a few hundred failure-mon to the wind in my IV training.
