When Kourtney, Khloe and Scott arrive in the Hamptons, Scott's anxiety at being in his late parents' home town leads him back to old habits.
After Kourtney admonishes Scott for breaking the boundaries they've set for their relationship, Scott makes attempts to clean up his act.
When Kourtney learns that Kim is using her home for North's birthday party without her permission, she flies to LA to confront her.
Scott finally decides to make a change in his life and checks into rehab, but his commitment to stay wavers with each day.
After Scott unexpectedly leaves rehab early, he and Kourtney try to avoid repeating past mistakes. Meanwhile, Kim doubts her best friend's loyalty.
Khloe supports Scott further when she makes arrangements for them to host a podcast – but things get ugly when he backs out on French Montana's video.
