But now instead of running away from zombies (only concerned with himself), he will confront his fear and put the lives of others before his own. He goes back and saves Jasmine in Hurl and Go Seek, he bashes up the Chris-bots in Scarlett Fever, and although he was initially scared by the robo-crocs he later faced them and bashed them up from the inside.

His development was he started off as a dirty coward who cared nothing about his friends, this costs him his relationship, he realizes there's more to life than running from the zombies, he changes his outlook on life and begins to put others before himself. That's how he developed.
