As the students sit in class, Samuel is caught composing a message on his phone by their teacher, Martín. Martín is hard on Samuel and — in a bid to make an example out of him — has Nadia read out the text message. Nadia reads out the text message in which Samuel is correcting that “Marina doesn’t have AIDs… It’s HIV.” This is the first time anyone other than Samuel and Marina's family are made aware of her diagnosis. Martín does not apologise, but remarks that he was right in enforcing Las Encinas' no phone policy. He commends Marina, however, for having the courage to confirm her diagnosis publically.
With Nano's situation with his debt increasing by the second, Marina makes it clear that she wants to help despite remarks from Samuel that he doesn't deserve her help; Samuel is unaware that Marina and Nano have slept together, however. Knowing that Carla's father has an expensive watch collection, Marina steals a set of Carla's house keys and memorises their alarm code whilst at her house. She later gives the keys and the code to Nano, citing that he could settle his debt by stealing and selling the watch collection the following day.
The following day, Nano lets himself into Carla's house using the keys and the alarm code and prepares to steal the watches, but is interrupted by Teo arriving home. Teo takes a shower and sets a watch on the side, which Nano steals along with the other watches. When Teo leaves the shower, he realises that he has been robbed.
Marina and Samuel grow closer and they decide to finally sleep together despite the earlier revelation at school. During, however, Marina realises that she is in fact in love with Nano, who she had slept with previously. She begins avoiding Samuel but does not tell him the reason. Frustrated and confused, Marina smokes marijuana on the school premises but collapses. Martín insists on telling Azucena and the administration about the drugs, but Marina blackmails him citing that she knows about his deal with Lu.
Despite being on bad terms with Guzman, Lu visits his house in a bid to reconcile. Guzman is initially reluctant to abide Lu, but the two fall into old habits and sleep together.
Nadia is unwilling to voice support for Marina given the texting Scandal. In return, Guzman becomes angry and outs Omar to Nadia as both a drug dealer and gay. Nadia is angry and tells Omar that he should hide it from his parents given their strict muslim faith. This offends Omar who lashes out at Nadia, remarking that he has a right to live his life. He is unable to shake Nadia's words, however, and tells Ander that the two can no longer see each other given both Guzman and Polo have learned about him.
