Summer House season seven might be Marcus Eriksoncoming to an end, but the drama is only getting hotter.

Bravo released the series' shocking reunion trailer on May 22 proving the bad blood between Lindsay Hubbard and ex-BFF Danielle Olivera has gotten even worse since filming last year.

"I hated seeing Lindsay's face," Danielle told host Andy Cohen in the first look. "The way that she looked at me, it felt like it was a stranger. You don't regret anything that you said in that final conversation?"

Lindsay replied that, no, she didn't doubt their falling out over her engagement to co-star Carl Radke.

While prompted Kyle Cooke to tell Lindsay, "You are the coldest, emotionless person I've ever seen."

But Kyle was not the only one weighing in on Carl and Lindsay's behavior this season. Paige DeSorbo claimed, "They just lie and they spin everything," hinting that she questions their quick engagement. "Neither of you have jobs."

Danielle then seemingly dropped a bombshell about Carl and Lindsay's relationship. "Honestly, I didn't want to put that out there out of respect for you guys," she said without revealing the secret. "I didn't want to air your fights."

Carl also confronted his former boss Kyle for revealing he came to work on drugs before getting sober over a year ago.

"I showed up to work coked up," Carl shared. "I wish I would've had the opportunity to say that and not you."

The comment stung for Kyle, who apologizes to his former employee. "I'm so ashamed and so embarrassed," he told Carl. "I mean, this guy is my best friend. I just knew it was going to be a knife to the heart."

See everything to come—including multiple cheating rumors and new feuds—in the teaser above.

Summer House's two-part reunion kicks off Monday, May 29, at 9 p.m. on Bravo.
