The feud between Kris Jenner and Scott Disick heats up on Sunday's Keeping Up With the Kardashians finale.

In a clip (watch above), Scott, 26, apologizes to Kris for getting inebriated at daughter Kim's 29th birthday. But he ends up going off, accusing Kris of treating him "totally different" than Kim's beau, Reggie Bush, and Khloe's husband, Lamar Odom.

"I don't know what I did to deserve you to hate me," says Scott, who has a 2-month-old son, Mason, with Kourtney.

Kris admits she treats Disick differently - but she doesn't feel bad about it.

"I'll never be able to trust him with my daughter or my grandchild ..." she says. "There's no place for Scott in our family any more. It's just too dangerous."
