At this point, we're eight years into the Zombie Apocalypse. When the show began, it had already been three years, then there was a two-year time jump between the third and fourth season.

I'm not sure about the others, but he's definitely grown to have respect for Warren.Keith Allan has done a really good job with the character... Murphy is still snarky, but grown as a human. His "intervention" seemed really sincere, and he really has grown to respect the others.
Well, he's gone through a lot of changes, from reluctant VIP to Zombie Messiah to suburban nerd, but he's never stopped being a self-centered jerk.I didn't really watch the first season.... how would you guys say Murphy has changed?
