The first clip catches everyone off guard, including Kim, when Scott's surprising presence inside Kourt's house breaks the fourth wall of the docu-series.
"I am like in shock," says Kim to an off-screen producer. "I haven't seen him in so long. He obviously spent the night and Kourtney didn't mention that he was there! I thought Kourtney was really strong and firm and now are they back together? What is he...I just don't understand."
#ICYMI: Scott and Kourtney, who have never been married, broke up this past July. Since then the newfound bachelor has been spotted with various other women and even entered a rehab facility in an effort to tackle substance abuse issues.
