Things are getting ugly down South!

Tensions come to a head between Shepard “Shep” Rose and Craig Conover on the reality series Southern Charm, and it looks like tonight things might finally hit the roof – or rather, the naval deck.

And it all goes down during a charity auction.

In this exclusive sneak peak of the season 2 finale, a woman bids $5,000 on Conover, leading his friends to believe that his head will “further engorge.”

“Craig thinks he’s so cool right now, I want to kill him,” Rose says.

Then, an unknowing Conover joins his annoyed friends on the deck as he looks for his date.

“My life’s pretty f–king sweet right now, ” Conover says. “I’m sick of acting like it sucks,” to which Rose responds: “What do you have, a girl that fake-bought you?”

After a season full of lectures, Conover declares, “I’m done.”

Could this be the end of our favorite Southern bromance?

Find out when the Southern Charm season 2 finale airs tonight at 10 p.m. ET on Bravo.
