90 Day Fiance: Before the 90 Days Season 4 Episode 15 - It was the season 4 finale and while we didn't see Ash and Avery at all, we did check in with Yolanda whose daughter has now hired a private investigator to find out the truth about Williams. Elsewhere, Darcey reveals Tom has been trying to reach out to her, Big Ed mends things with his daughter, Geoffrey re-proposes to Varya, Stephanie tells her mom she's bi-sexual, Lisa marries Usman and David continues to creep us all out by inappropriately grinning at Lana.
