Last night's episode of Sister Wives focused on blending the fourth wife — and her children — into Kody's family. So far we've seen how the adults are dealing — but what about the kids?

As if the trainwreck of a show didn't have enough drama with the one husband/four wives/13 kids thing, this sneak peek from the upcoming episode of Sister Wives features tears over one of the wives kissing her husband.

Police in Lehi, Utah are looking into the marriage of TLC star Kody Brown and his four wives. The cops admit that the show's publicity is what prompted the case.
