On this Sunday's Keeping Up With the Kardashians, Khloe says that Scott acted like a "negative, depressed victim" during a recent family dinner celebrating the late Robert Kardashian's birthday.
Khloe tells her sisters that Scott "acts like he's tries so hard" to be present and get along with everyone, but he "comes and plays this victim."
After witnessing his behavior at dinner Khloe told Scott, "I'm gonna punch you in your f--king jugular because of your depressed, negative energy."
"But he's depressed," Kourtney says.
When Khloe gives Kourtney a look, she tells her, "I don't like it."
"He's not making an effort whatsoever to come to mom's with a little smirk on his face," Khloe tells Kourtney.
Khloe then goes on to reveal what Scott has to do to have a relationship with their family!
