'Big Love' first look: Mom and Dad still love you, Ben

The downward spiral of the Henrickson clan on "Big Love" seems to know no end -- though it will presumably come to a halt with the series finale in a mere five episodes.

Their latest obstacle? Divorce. During the Feb. 20 episode, "D.I.V.O.R.C.E.," Barb (Jeanne Tripplehorn) and Bill (Bill Paxton) announce their formal split as a part of Barb's gender-barrier-breaking pursuit of attaining priesthood status.

Ben (Douglas Smith), as you might imagine, doesn't handle this very well. Of all the grown Henrickson kids, he's always been the most supportive of polygamy and their faith's strict rules. And in this exclusive preview clip from HBO, he offers his parents some Internet print-outs on how to salvage their marriage.

Reading material solves everything.
