Daniel opens up about tragic parts of his childhood, Ronnie has a breakthrough in his one-on-one with AJ, and everyone gets one last opportunity to share their secrets.

AJ invites six couples to Las Vegas to work on their issues, Kendra accuses Joc of not fully owning up to his infidelity, and Falynn questions why Jaylan won't set a wedding date.
