So Seth MacFarlane killed off Brian Griffin.

And the only two things I'm thinking right now are:
Good riddance to a preachy strawman character.

And this advert for the episode in question has an incredibly ironic quote in the first few seconds.

How is it Ironic? If you know anything about who Thomas Aquinas is and how Seth MacFarlane jokes about people like him in his shows, you'll know why.

And that is all I am saying on the matter.
