Keeping Up With The Kardashians returns with a new episode on Sunday and Khloe is caught having to be the voice of reason to Scott Disick...again. Kourtney Kardashian has left town with their kids for a month and has left Scott in L.A. to do his own thing, which has not gone well in the past considering Scott's problem with drinking. "Are you going to be on your best behavior?" Khloe asks Scott. "Worst" Scott replies with hopefully, sarcasm.
