Papi comforts her, telling her about how he was a chamberlain at a friend's Quinceanera when Pedro finds a picture in a box marked "DO NOT OPEN".

Back at home, Rosa fakes being sick to avoid going to school but when Papi says she will have to go to the vet, she claims she is feeling better.

But in the midst of the party planning, Papi continues to be his paranoid self and was pressured due to the lot of errands he has been working on.

As more proof of Jenny and Oscar scheming something behind their backs, and Rosa saving a dog, Charlotte, who was a VIP guest at the hotel, they contact Delgado, to help with their plan on catching Jenny and preparing Rosa's quince.

She trips and falls into a large puddle of peanut butter, and Pedro calls more dogs.

When Hollis overhears the commotion, Pedro opens the gate, and Delgado appears with Montague, the competitor hotel manager, hung upside down.

Jenny and Oscar are arrested, Papi becomes the new teacher at the doggy day care, and Hollis adopts Arnie.
