Rob Kardashian and Blac Chyna’s engagement becomes the focus of the latest episode of “Keeping up with the Kardashians.” In Season 12 episode 3 titled “Significant Others and Significant Brothers,” Kim and Khloé take umbrage after their brother fails to mend ties with Kylie and the rest of the family.

Rob’s relationship with make-up artist Blac Chyna aka Angela Renee has been debated a lot by the Kardashian siblings. Rob’s fiancée, after all, shares a son with Kylie’s ex Tyga. A few episodes ago, Khloé mentioned she’s been in the dark after her brother started dating Angela. This isolation is expressed again in Season 12 episode 3.

Khloé emphasises that Rob, who secluded himself from the public earlier, has been more active on social media now than ever before. She adds that this change in his personality and attitude has “blown her mind.”

Kanye West’s wife, Kim, listens to Khloé and acknowledges that Angela has inspired their brother to be confident. However, she adds that Rob’s failure to mention the significance of his relationship with Angela is troubling. “Kylie should have known this. He has no loyalty,” she says.
