The episode centers around the Walker family, and 11-year old Carl Joseph-Walker Hoover who took his own life because he was bullied. The Kardashians and Michael Moloney set out to make new memories and rebuild the third floor of their home where their boy took his own life.

“For me, I was bullied my entire elementary school and high school. I had the hardest time with it. I would never talk about it. I would internalize everything,” Khloe revealed on the show.
