The entire Brown family will continue exploring the Alaskan frontier in the upcoming episode of the hit Showtime reality series "Sister Wives."

In "Meri Catfished," TV Guide reports that Kody, his four wives, and their children will enjoy what Alaska has to offer, including dog sledding and deep-sea fishing. Robyn's sensitive nose, however, will put a damper on things, as her hormones suddenly decide they do not like the smell of raw fish. Meanwhile, Logan and his girlfriend will reportedly go on a double date with Madison and her beau.

In episode 11, Madison told her parents that she was in a serious relationship with Caleb Brush, Kody's brother's brother-in-law. Kody and Janelle approved of the relationship, as her father told Madison he could not have picked anyone better for her. The synopsis reveals that Caleb will later approach Kody for a man-to-man chat about his daughter.

As for Meri, she will admit to the family that she has been involved with a man she met online. But things did not turn out well after she learned that he was not who he said he was. The Alaskan vacation is turning out to be a trip of revelation, as last episode, Kody and Robyn revealed the gender of their baby. The news came after the good turnout of the adoption request for Robyn's three children from her previous marriage. The trip was to celebrate both the court's decision and the Brown's eighteenth child.

The expectant parents chose the youngest of the brood to share the good news. Truely and Solomon were tasked to unwrap a box and reveal its content. When the two saw a pink baby doll, Truely shouted that the baby is a girl. It turned out that Solomon's previous guess about his new sibling's gender was spot on. The other Brown children could not contain their excitement, but it was Hunter's pronouncement that endeared him to the viewers.

"I feel like I have a lot of sisters, but that's OK. I want more. I just love my sisters so much," he said.

"Sister Wives" airs Sundays at 8 p.m. on TLC.
