Painful truths and dark secrets are exposed as the students unburden themselves and the circumstances behind Samuel's disappearance are revealed.
Nadia and Guzmán are the laughing stock of the school after the video of them having sex is released. Nadia is ashamed and says she never should've done it. Valerio admits to her that he released the video. Later on, Nadia tells her family that there is a video of her that will bring shame to the family. Her family comforts her and tells her to erase it and never show it to them.
There is a lot of mystery surrounding Samuel's disappearance. Everyone turns on everyone, doubting their motives and intentions. In the search party, Samuel's bike and bloody jacket are discovered. Carla asks her father if he was behind Samuel’s disappearance; he passively denies any involvement. Rebeka blames her mother and says that getting Samuel involved in her illegal activities is what got him “killed”.
At a Christmas dinner, Lu brags about all the awful things she has revealed at the school. Valerio is disgusted by her actions and decides to get revenge by revealing to their father their sexual relationship. The family is furious and Valerio tells Lu that she no longer is anything to him except his sister.
Polo goes to Cayetana's house to tell her that he got her back into the school, her mother's job back, and he gives them a bunch of money to cover immediate expenses. Polo explains that he believes everyone deserves a second chance. Cayetana and her mother gratefully accept.
In a flashback, Guzmán messages Samuel and tells him that he believes his story. Samuel asks to meet in a quiet place. This is when he bikes on the deserted road and gets followed by mystery men in a large car. Samuel runs and finds Guzmán, who hides with him as the men walk away. Samuel and Guzmán come up with a plan: Samuel will hide in Guzmán's grandparents' country house indefinitely while everyone thinks he has gone missing or is dead. Then Guzmán will plant “evidence” of Samuel’s potential death, such as his bloody jacket which was found in the forest. Samuel thinks that this plan will force Carla to eventually crack and confess the truth out of guilt.
In the present, the Inspector gets a search warrant for Guzmán's grandparents' house, seeing as this was the last place that Samuel had cell service. They search the property and don't find anything until the Inspector sees Samuel, alive and well, in the boiler room of the house. They come to some kind of agreement because the Inspector walks out and claims she saw no one.
Carla eventually cracks and goes to the police to confess everything. Samuel comes out of hiding and lies that he was at a "rave". It is revealed that the Inspector agreed to go along with Samuel's "disappearance" in order to manipulate Carla into confessing. Before the police arrest Polo, he confesses the murder to Cayetana. She repeats to him that everyone deserves a second chance, and implies that she could steal the murder weapon so that there is no case.
Polo finally gets arrested at school. Guzmán is enraged at Ander and cuts ties with him, since he knew the truth the whole time and didn't say anything. Cayetana is later seen hiding the murder weapon in her closet. In custody, Polo denies the accusations and doesn't confess.
Omar is packing his bags, about to leave Ander’s house and break up with him, when he learns of the true murderer and the fact that Ander was hiding Polo's secret the entire time. This explains Ander’s disturbed and apathetic mental state over the past months. Omar is shocked but forgives Ander, and the two finally rekindle their relationship.
At school, Guzmán and Samuel seem friendly. However, everyone, including Carla, is shocked when Polo abruptly returns to school after New Year's; he has been released from custody. Only Cayetana is happy to see him, and behind Polo is a new student talking with the principal.
