Check out this sneak peek video of the explosive “Gang Related” finale, titled “Malandros,” or “Thugs,” which sees Ryan Lopez (Ramon Rodriguez) and Sam Chapel (Terry O’Quinn) out to avenge Jessica’s (Shantel VanSanten) murder.

“What would be the most difficult thing to happen to Ryan? What would be the most traumatic thing that would crush him?” says Rodriguez. “Losing the one person in his life where he saw a potential future, things that he never had, maybe his own family. I think that was the crushing blow, it’s one of the triggers that leads to the finale.”

The finale sees Ryan and Chapel heading up a manhunt to Mexico, looking for Matias, who they believe is responsible for Jessica’s death — and they’re willing to do anything to catch him.

“This is a grieving father that’s willing to do anything, and I think Ryan is completely on board with that,” says Rodriguez. “They’re on parallel journeys of finding out and avenging his daughter and my girlfriend’s death.”

“When Ryan finds out who was behind the murder, that’s when his life is completely flipped upside-down,” he adds.

The “Gang Related” Season 1 finale airs Thursday (Aug. 14) at 9 p.m. ET/PT on FOX.
