Overview:Sam, Aaron and Cain follow Zak out of the church and question what's going on. Zak admits he hasn't written any vows. When Lisa appears, Sam informs her of Zak's lack of vows. Zak explains to Lisa that he hasn't come up with anything as he's spent all week thinking how the next time they'll be in church is likely to be for her funeral. Lisa insists that's all the more reason to enjoy this.
