'Southern Charm' Showdown! Kathryn C. Dennis and Whitney Sudler-Smith's Explosive Argument

What was Whitney Sudler-Smith thinking when he pushed Kathryn C. Dennis' buttons during the last episode of Southern Charm? MStars News has watched the explosive argument that had Thomas Ravenel's baby mama fired up and ready to punch somebody.

In Monday nights episode it was pure drama as the cast of Southern Charm went away to Jekyll Island to relieve some stress and get away from Charleston. Thomas was too busy campaigning for Senate so he was stuck back at home, but his girlfriend, Kathryn, went along for the trip but didn't bring their sweet precious daughter, Kensington.

In the clip below, Kat comes down from changing into something comfortable, all eyes are on her as Whitney starts to gossip about her until she sits down.

"Kathryn they're challenging our friendship and saying that I'm disingenuous and why you're a confiding me," Craig Conover said. An outraged Kathryn gets up and points her finger at Whitney and said: "You want to challenge me? You don't know sh*t!"

As everyone tells Kat to relax and start laughing, she yells at Whitney, "You should go home and take lessons from your mother," as Whitney tells Kat to go to bed.

Kathryn replied with a weird comment, telling Whitney he "should go fall on a knife." Shepard "Shep" Rose admits that his friend, Kat, looks like she could "kill Whitney," and from the looks of her face, she does! It's kind of hard not to laugh at, but why is she so fired up?

MStars News guesses it's all the crap built up from the campaign and all of the rumors Whitney spreads about Kathryn.

"Y'all push her to this point," one of the other friends claimed. "Where she feels so threatened." Rose denies those claims and responded back, "That's insane! Are you out of your mind?...I'm the nicest guy on earth."

As Kat tells Whitney to "go f*uk yourself," some of the other group members start to leave the heated dispute. "It was fascinating, I've never seen people act that way," Rose admitted.

As Whitney continues to sit in his chair and get yelled at, Rose tries to calm down Kat by telling her, "Stop. I thought we were on an island that was founded by the national convention of music?"

Stay tuned for next weeks episode. MStars News is pretty sure this drama isn't over.
