Kourtney & Khloe Take the Hamptons, Trouble In Paradise

Here we go again! When Kourtney, Khloe, and Scott arrive in the Hamptons to start their picture-perfect summer, Scott runs back to his old habits.

Family the the rescue? Khloe tries to get Scott on a healthy track with tennis, but it backfires when Kourtney accuses her of taking Scott's side.

What's worse than borrowing your sisters clothes? Borrowing her home. Kourtney learns that Kim is using her home for a birthday party without permission.

Anyone can change, right? Scott finally decides to make a change in his life and checks into rehab, but his commitment to stay wavers with each day.

Have things really changed? After Scott unexpectedly leaves rehab early, Kourtney and Scott try to avoid repeating their past mistakes.

Khloe takes her support of Scott to another level when she arranges for them to host a podcast, but things get ugly when Scott backs out on a promise.

There's nothing like a supportive family. When Khloe rekindles her love for horseback riding, Scott and Kourtney make a wager on how long she will last.

There are just too many bad feelings for Scott to move on. When Scott is consumed by his negative associations with the Hamptons, he decides to leave.

It's hard to move on. Scott is still unable to set foot in his late parents' house, so Kourtney gets to work on fixing it up, hoping he'll keep it.

What a season finale! When Khloe indulges in a night of drinking, Kourtney grows livid and accuses her of recklessly putting Scott's sobriety in jeopardy.
