George thinks Rosie's fiancé might be hiding an unholy secret, so he goes undercover to get him to confess and expose the truth. With wedding bells in the air, Chance puts pressure on Mayan and Quinten about why they're not married.

Secrets rain down on the Lopez clan like candy from an exploding piñata when Mayan invites her therapist, Dr. Glenda Brenda, to mediate some family drama at Rosie's engagement party.

Mayan and Quinten refuse to let George and Rosie hijack their vision for the upcoming wedding, even if they have no idea what that vision is; Oscar teaches Chance how to be the best "best man."
