Kourtney and Khloe Take the Hamptons Season 1 Episode 3 features a fight between sisters. But not between the sisters who star on this E! reality series.

Instead, Kourtney takes off for Los Angeles to have it out with sibling Kim Kardashian because is planning to "borrow" - without permission, that is - Kourtney's home for North West's first birthday bash.

Elsewhere, too much partying in the Hamptons places Scott Disick in the hospital and prompts him to arrive at a realization that things need to change. Yup, he may need to go to rehab.
