In the last part of the reunion special, the tensions and conflicts between the Housewives won't end any time soon.  

Before the intense faceoff of Kim and Kyle Richards in "Real Housewives of Beverly Hills" Season 5 Episode 22, fans have watched their relationship started to crumble down. Though they had their ups and downs through the years, Inquisitr shared their relationship deteriorated even more when Kim felt Kyle doesn't have her back. While Kyle felt Kim's actions towards the other Housewives are indefensible.

As the Housewives reminisced their experiences and expressed their grievances, the Richards siblings hit a major breaking point. We previously reported that several "RHOBH" Season 5 Reunion spoilers suggest Kim's alcohol issues and her acquaintance with Brandi Glanville were to blame for the escalating rift between the sisters.

At the beginning of "RHOBH" Season 5 Reunion special, it was revealed that Kyle and Kim have not spoken for months.

In the "RHOBH" Season 5 Episode 22 sneak peek posted on Facebook Monday, the caption teased that the real reason of the Richards' feud will be finally revealed. Fashion & Style added the root cause of their escalating issues was when Kim's dog Kingsly attacked Kyle's daughter. However, the defining moment of the conflict transpires when Kim slams Kyle for making her daughter's accident into a public display on Instagram.

And as Kim becomes upset and furious, she threatens there's more to the story that she has never told and when she does, her sister Kyle will not going to like it.

"Do you really want me to tell the whole story? Do you really want me to tell what happened? Kim asked. "How, when we got home, what happened and how she actually - it really happened? I've never told the story. I'll tell the story and you won't like it."

Meanwhile, as "Real Housewives of Beverly Hills" Season 5 Episode 22 synopsis reads, "The reunion concludes with plenty more drama and a little bit of humor. While the women can laugh about who has the dirtiest mouth, things turn sour when Kim reveals threatening texts Lisa Rinna sent her after Adrienne's party.
