Polyamorous Family - S1.E5

Can a multiple-partner marriage work? Is 3 really better than 2? Dawn was first married to Troy, but then both of them fell in love with Lon. Now they consider themselves a married "triad." How does the household work? Sleeping arrangements? Polyamory is not widely accepted and society's prejudice against this form of marriage causes this triad to lose custody of their young son.
