We're only one episode in to the final season of Big Love, but it's never too early to discuss the upcoming series finale, is it? We didn't think so.

Creator Mark Olsen says the drama's final three episodes will be "astonishing," highlighted by the "ultimate and final showdown" of Bill versus Alby.

Fans can also expect a rift within the Henricksons that could lead to divorce; an unexpected marriage; and a "great tragedy" in the final episode that is responsible for the return of Sarah.

Says star Bill Paxton to TV Guide: "We want to go out big... I don't think [fans are] going to be disappointed with how it ends."
