Joaquin has a nightmare about the girl he was looking for, calling him out for stopping the search for her.

He wakes up to a box at his door. Kelly is throwing a murder mystery party. She wants everyone to dress up.

Everyone dresses up as various characters and caricatures. Kelly is playing dead and the others have to figure out who killed her. Everyone is paired up.

Things are a bit awkward when Angelica is catering the event while Isaac is there.

Joaquin is distracted and out of it while Mariana is having fun.

Davia is invested in the murder mystery while Dennis is distracted. They keep arguing.

Luca is hesitant to show Mable his room, which is part of a clue.

Kelly randomly asks Gael to be her sperm donor when she freezes her eggs.

While looking through Mariana's room for clues, Isaac finds her anti-anxiety meds and appears tempted.

Luca shows Mable his room and tells her how he's worried about what Riley would think about things like that, and Mabel tells him he needs to stop judging Riley and assuming the worst, and making snap judgments about her.

They almost kiss but don't.

Joaquin seems to blame Mariana for not looking for Madison, and she tells him she was only pointing out that he was getting too obsessed. He calls her out for dropping everything for Evan. They part ways.

Malika is monitoring Isaac's drinking, which prompts Isaac to blow up on her for micromanaging him.

Joaquin goes to the roof to apologize to Mariana. He tells her how part of wanting to take down Silas so much is he reminds him of his father, who used to hit him.

Isaac admits to Malika that he went cold turkey off the meds he was taking.

Isaac urges Malika to rekindle something with Angelica.

Kelly says she wants a child because she's afraid that no one will ever come to her funeral. Gael tries to convince her otherwise.

Malika tells Angelica about her feelings and says she knows she feels the same. Angelica says she'll think about it.

Kelly realizes that Gael is right when they give her a birthday cake and sing to her. She is loved.

Sumi wants to move in with Alice, and Alice is freaking out because she doesn't know if she's ready to leave the coterie behind.  They talk about how they need time and money to buy a house, so they still have time.

Isaac took some of Mariana's pills and pops them alone in the room after the party.

Luca realizes that he may have feelings for Mable when she leaves, and he doesn't want the night to end.

Mariana and Joaquin are still playing around in character when they kiss. But he breaks away and tells her that he can't be casual with er as long as she has feelings for Evan.

Joaquin notices Kelly coming in from the window and realizes that Silas may have come in through there. He has his friend check it for prints and gets a match.
