90 Day Fans Shocked After Therapist Persia Lawson’s Dark ‘Serial Cheater’ Past Surfaces Before Episode 2.
Jenny Slatten and Sumit Singh, Shekinah Garner and Sarper Güven, and the rest of the Season 3 couples aren’t the only stars of 90 Day: The Last Resort Season 3. It’s about time we meet the three therapists: Persia Lawson, Dr. Tyrone K. Grandison, and Dr. Tara Suwinyattichaiporn, guiding our couples through their journey towards recommitment.
During Episode 2, the couples will be guided through an etiquette-forward dinner at Thornbury Castle. From Swooon‘s exclusive preview of the dinner alone, it’s clear that tensions between Kara Leona and Guillermo Rojer and the rest of the couples are already running high.
“You are here because your marriages are in a state of crisis and dysfunction,” Persia Lawson told the couples. “Our role as your therapists is to guide you to reach a better place in your relationships.” Scroll to find out all about this season’s therapists!
