90 Day: Darcey Exposes Florian's Suspicious Club Antics to Stacey After Learning He Took Another Woman Home (Exclusive)

Florian is in for a rude awakening.

In PEOPLE's exclusive first look at 90 Day: The Last Resort, Darcey takes the opportunity to inform her twin sister Stacey that she heard rumors regarding her husband Florian's wild night out.

Darcey begins by extending an olive branch to her sister, and apologizes for her antics before sharing evidence of Florian's alleged infidelity.

"I love you, and no matter what in life, we're twins for life, and I'll always have your back," she prefaces, as Stacey returns the sentiment. "I just want you to know that couple weeks ago, me, Lauren, [my husband] Georgi were all out one night, and we saw Florian walk away with two blondes."

When Stacey asks if the women were "all over him," Darcey doesn't confirm but reveals that she tried to give him the "benefit of the doubt" as he escorted them outside.

"But I got a text from Georgi," she continues. "Georgi's at that same bar tonight that Florian was at with those two girls, and one of the girls that was there that night, that he walked away with, said something to Georgi."

"She walked right up and said, 'Tell Florian, thank you for taking me home,'" she adds to which Stacey's jaw drops and replies, "What the f---?"

In a conversation with cameras outside the bar, Darcey says recalls how she received a message from Georgi, asking her to call him "as soon as you can." As soon as she answered the phone, he informed her that he recognized one of the blondes from the night before.

"They made eye contact. She came right up to the table. It was almost like intentional from what Georgie said her tone was," she says.

"So Georgie was left stumped. He didn't know what to freaking do. but at the end of the day, like she needs to know this information," Darcey adds.
