Tupi

Tupi is a dangerous young man who is a gang member and the boyfriend of Mia Benitez.

Season 3
After getting out of prison, Tupi reunites with Mia, having sex with her in J's house. Tupi fails to wear a condom during sex, annoying Mia when he orgasms inside of her which Tupi brushes off.

Season 4
Tupi continues hanging around Mia and J's bowling alley, drawing J's ire because of his suspicions about Tupi. Mia introduces Tupi as her foster brother so as not to alarm J who doesn't really buy it. The two are shown to be plotting to rob J with Tupi becoming impatient. Mia later murders one of Tupi's friends behind his back and tricks J into being her getaway driver, enraging J who ends their partnership. Tupi subsequently assaults J outside of the bowling alley for upsetting Mia, but runs off when J draws his gun. Tupi and Mia later rob J and wreck his house.

Things come to a head when Tupi and Mia rob J's uncles on their way back from a job. Tupi can't resist taunting them to tell their nephew that he said hi, causing J to realize who the culprit is after learning of the taunt from Pope. Though J lies about knowing who the culprit is to his family, he reveals Tupi and Mia's activities to an outraged Pete. Confronted by the appearance of J at Pete's shop, Tupi quickly claims J has been lying and denies any involvement in the robbery, offering to kill J for Pete which Pete refuses. After spotting that Tupi is wearing one of the stolen chains around his neck, Pete knocks Tupi to the ground and executes Tupi with a shot to the back of the head before leaving Mia to J. Mia shows no real care for Tupi's murder and tries to convince J to resume their own partnership. Instead, J kills Mia himself, leaving her body on the floor next to Tupi.

After the deaths of Tupi and Mia, J recovers the stolen goods from Tupi's truck and pays Pete to dispose of the bodies for him.
