Seems like they're gonna bring him back. It was a way for ratings and I say it worked. But people who gave up on the show tuned in for the episode. They said 'It was an idea we tossed around the writer's room and we wanted to see how the dynamic would change'.
I meant Season 4 of Family Guy unless that's what you meant too. Yeah, that was a great episode. Season 10 was pretty great overall. I like how they got the extra jabs at Scientology with that episode.
