In the beginning, I thought he was a goddamn asshat, but once I knew his background he became a lovable asshat. After a period of hurting and heartache, he defined himself only regarding Garden's matters, until he let himself open up again (yes, it took a crapload of time) which was quite a payoff.
I liked his inner monologues by the way, I thought most of them were hilarious which wasn't what was intended, that made them that much funnier for me.
