Today, the whole truth comes out in the "Sister Wives" season 6 Tell-All episode. Meri is prepared to tell everything about the catfishing scandal that she recently got into in front of her former husband Kody Brown and his wives Robyn and Janelle.

TLC teases that the installment, which serves as the actual finale of the show's season, "takes on jealousy, the headlines, and what's next." The network promises that in this two-hour season-ender, Kody's former legal wife will drop the "most shocking development" in the show's history.

Fans may have already heard about Meri's dilemma about engaging in an online relationship with a woman impersonating a man. In the last regular episode of "Sister Wives" season 6, Meri already spoke about the problem but the "Tell-All" episode will see her tell her family the whole thing.

Kody is still bemused about what's going on with his former legal wife. In the last episode, he already expressed his worry about Meri's possibly no longer wanting her married to him. In the promo for the two-hour special, he looks as confused as he was as Meri elaborated on the catfishing crisis.

Apart from Meri's predicament, the "Sister Wives" season 6 "Tell-All" will also touch on Kody successfully becoming the legal father of Robyn's three kids from her previous relationship after an intense and tedious battle in court. The Brown family patriarch is evidently ecstatic about the feat.

A sneak peek titled "Never Seen You Cry" shows Kody being emotional about winning the custody battle. He sheds tears, prompting host Tamron Hall of "Today Show" to say that it is the first time Kody is seen crying.

The "Sister Wives" season 6 "Tell-All" will also see wives Meri, Janelle, Christine, Robyn and their children provide a glimpse of what's to come. The two-hour special airs today, Nov. 22 at 9 p.m. ET on TLC.
