Oscar Torres, played by Aaron Dominguez, did not appear in the second season of Only Murders in the Building. The showrunners decided not to pursue his relationship with Mabel, as they did not want to see Mabel develop a relationship where the trauma bond is strong. In the first season, Oscar was freshly out of prison after being wrongfully convicted of murdering his girlfriend Zoe. During the investigation of Tim Konos murder, he fostered a relationship with Mabel. However, the first season did not give Mabel and Oscars relationship a proper ending, and he was not seen in the second season. John Hoffman, the showrunner, revealed that with all that Oscar had gone through with going to jail for murder, they thought his leaving made sense. The door is open for Oscar to reappear in future seasons, and it is possible that he could circle back to his old flame in Only Murders in the Building season 3.
