Rob Kardashian’s struggle with his weight loss resurfaced and ‘Lord Disick’ returns to ‘KUWTK’. The family headed down to San Diego for their grandmother’s 82nd birthday and Rob was missing once again. Rob was eventually confronted by his sisters when they returned home. ‘The Lord’ also returned on Sunday night’s episode, as the family felt it had been too long since they had seen him. Kim and Khloe attempted to rename ‘The Lord’ as “The Duke’ but Scott Disick was having none of that.
