As it turns out, before taking on the role of Torres, Benjamin Levy Aguilar also appeared on-screen in a 2019 episode of "Chicago P.D." The installment in question is "Chicago P.D." Season 7, Episode 1 ("Doubt") (via IMDb).
In this episode, Detectives Jay Halstead and Hailey Upton (Tracy Spiridakos) attempt to prove Hank Voight's innocence in the murder of Chicago mayoral candidate Brian Kelton (John C. McGinley). Early in the investigation, detectives discover that Franco Chavaro (Aguilar) is the owner of the gun used in the killing. To put it mildly, things aren't looking very good for Chavaro at this point in the process. However, it is later realized that an officer in the Chicago Police Department stole Chavaro's gun during a prior raid. As a result, Chavaro would have had no access to the gun at the time of the murder, and he is thus eliminated from the investigation.
While we haven't seen Chavaro return to the series since Season 7, it's notable that the series' creative team was willing to introduce a second character also portrayed by Aguilar, especially after only two seasons away. Interestingly, Aguilar is not the only actor to play two characters on "Chicago P.D." Kurt Naebig first played Lt. Bruce Belden in the first season of the series and returned in Season 9 as a totally different character.
