It is revealed to be the night of Marina Nunier Osuna's Death. On the last day of school, June 1st, Marina planned to leave with Nano to avoid the abortion her father planned for her the following day. Marina and Nano planned to move to Morocco and raise their child, with intentions of inviting Christian and Samuel over in the summer.
The same night, Marina wins Las Encina's trophy given Nadia and Lu are unable to take their exams. At the graduation party, Marina leaves early to wait for Nano by the pool. She is approached by Polo, however, who is dead set on winning back Carla's trust — and her love — by retrieving the watch from Marina. The two get into an argument, with Polo pleading with Marina to hand over the watch. She refuses, and after Marina says hurtful things towards Polo, he hits her with the trophy causing a head injury. Marina and Polo are both shocked by the events, and Marina collapses moments later. Concerned about what he has done, Polo takes the trophy and flees the scene to the locker room.
Inside the locker room, he begins cleaning himself off before he is noticed by Christian and Carla who are having sex. Carla questions what has happened and Polo hands her the watch explaining that he killed Marina. In fear of Polo being found out, Carla forces Christian to help her cover up the murder and asks for a spare shirt for Polo to wear. After he is cleaned up, they return to the dance and act like nothing has happened.
Nano arrives at the pool as planned and finds Marina bleeding from her head. He runs towards Marina who falls into his arms, dead. He calls out for help but is unable to get a response. Panicking, Nano flees the scene also, but is witnessed by Samuel who believes him to be guilty.
The Police arrive shortly after Marina's death. The detective takes everyone into custody and it is revealed that Nano is the suspect, given Samuel saw him running from the scene. Polo is revealed that the spotlight is not on him. Guzman blames Samuel for introducing Nano to Marina, but Samuel rebukes him, citing that he came to Guzman for help but was dismissed.
Guzman is utterly heartbroken by his sister's death and Lu finds him on the ledge on the edge of town about to jump. Lu is able to talk him down, and Guzman admits that he needs her. Everyone seemingly moves on from Marina's death shortly after with Polo under the illusion that he is safe.
