While Kourtney and her sister Kim were partying in Mexico -- and tabloid reports of Kourtney going on a date had already started to circle online -- Scott decided to have a fun family night camping in Kourtney's backyard with their cute kids -- Mason, Penelope and Reign.
They were joined by family matriarch Kris Jenner (who hired a team of people to assemble all the tents) for a fun day of outdoor games and a night under the stars with as many creature comforts as humanly possible.
But, after a great day of making s'mores and playing games in the grass, drama reared its head when Kris Facetimed Kourtney in Mexico, and the reality star shared some details of her wild escapades the night before.
Speaking with the KUWTK cameras on Sunday's episode, Scott opened up about his conflicted emotions regarding Kourtney's life apart from him.
"The last thing I want to do is really hear exactly what Kourt's doing on this Mexican getaway," Scott said in a solo interview. "Obviously, Kourtney having a good time makes me happy. But of course in the back of my heart and mind I get a little jealous, because I wish we could have had some of those type of times while we were together."
