Ain't going to happen, the end of every episode is a prayer lead by Phil.
The family will not stand for him to be missing.
They have a son named Alan that is not on the show. He's a preacher so he'll probably step up or they'll let Willie do the prayers. I think I read on FB that they've already filmed the next season so there may be a LOT of editing done before it airs - IF it airs.
