In a nutshell: Foreman quits. House fires Chase on a whim. Cameron quits.
Though he was visibly struck by two out of three developments, House seemed content in the end. I'd like to think he's looking at the silver lining: Now that he's pushed his staff away, he can't hurt them anymore.
Am I giving House too much credit?
All of this sets up one heck of a writers' challenge for next season.
