The Kardashian/Jenner clan will face a very bizarre situation in the latest instalment of "Keeping up with the Kardashians." In Season 12 episode 7 titled "Snow You Didn't," Kim, Khloé and Kourtney will realise just how serious Rob's relationship is with Blac Chyna.

Remember the time the Kardashians were vacationing in Vail, Colorado, and Rob announced his engagement to Blac Chyna? Everyone wondered why the sisters and the momager were so silent. The reason for their conspicuous silence will finally be addressed in the upcoming episode of the reality TV show.

According to the summary (via TV Guide), the first family of entertainment will learn via social media and texts that their brother has proposed to the woman he's been dating only for a few months. Khloé, Kourtney and Kim will feel terribly sidelined and distanced from Rob, who proposed to Chyna in front of her family.

"We wake up to all of these pictures of my brother getting engaged," Kim says in the promo for Season 12 episode 7.

Although Kim will be more measured in her response to Rob's engagement, Khloé will feel slighted that their family was left out. She mentions, very pointedly, that Chyna's family was present at the time of the proposal.

"Everyone's calling us asking if it' true and we just don't know. How does our brother not tell us; It's just so hurtful," Kim adds in another promo uploaded on "Keeping up with the Kardashians" Facebook page.

If there's one person who is silent through this entire conversation, it is Kourtney. Perhaps this is because she faces more drama with her former partner and baby daddy, Scott Disick. The synopsis for Season 12 episode 7 indicates that Scott's behaviour will concern the eldest daughter of the Kardashian clan. But it remains to be seen why the father of three will unravel in the upcoming episode.

"Keeping up with the Kardashians" Season 12 episode 7 airs at 9 p.m. EST on Sunday, June 19, on E! You can live-stream the episode via E! Live.
