Continuity mistake: Early in the show when Vince is driving to the hospital after he is wounded by gunfire, he gets out of the car twice.
Visible crew/equipment: When the team of Special Agents are at the auto shop in Red Hook, just as Scola says, "Ethan Chen, you're under arrest," there's a visible pink nylon T-marker on the sidewalk. (00:20:15)
God Complex - S5-E23
Continuity mistake: The chase scene when Maggie, Tiff, and A are chasing the suspect is a total mess. Maggie radios in to say "he ran down the subway", but he doesn't and they pursue him in the streets. Almost immediately, the suspect hijacks a car three blocks away. They locate him in Queens, but now it's night and raining. However, when the chase began, it was bright daylight and clear. Maggie chases him into a crypt, and in the last scene, daylight is shining through a window.
All the Rage - S6-E1
Continuity mistake: The team is moving into an industrial space where they believe the perpetrator is hiding. There is a generator outside with a red power cord leading under the door they are about to breach. When they burst through the door, the cord is no longer there but it can be seen a few seconds later, but now it is black.
Unforeseen - S6-E6
Continuity mistake: Maggie chases and isolates one of the terrorists holding a cylinder of toxic gas. The terrorist pulls down his gas mask to speak to Maggie, but in the following few scenes, the mask moves from below his chin to all the way back in place.
Continuity mistake: In the opening scene, a victim is being chased through a wooded area with his hands tied behind his back with duct tape and duct tape over his mouth. He hides briefly behind a wall and emerges with his hands free and no duct tape on his mouth.
Continuity mistake: Early in the show, the truck driver slams on his brakes in a panic stop when he sees a body in the road. He does it twice.
Answer: Felix Serrano was the biological son of Antonio Vargas, the leader of Durango Cartel. Miguel Rojas (has 2 priors in cocaine distribution, and he launders money), was a Lieutenant with the Durango Cartel, and he worked with Felix Serrano. As for the motive, Miguel shot Felix (his actual target) because they had a falling out, which was presumably drug related, and the four other men at the poker table were just collateral damage (Miguel attempted to make it look like robbery). Later, when Miguel was in Antonio's car wired up with the FBI body cam, Antonio states, "Felix said that things were not going well between the two of you." So Antonio knew Miguel murdered his son Felix. At the end of the episode, after Rina's press conference, note one of the reporters even asks, "What was the motive for the 5 murders?"
