Sweet Johnson

The pivotal mission. CJ and Sweet drive into a Ballas ambush at Glen Park, fight off waves of attackers, and the truth about the Green Sabre that killed CJ's mom comes out.
The Green Sabre is a mission in given to protagonist Carl Johnson by Grove Street Families leader Sean "Sweet" Johnson from his home in Ganton, Los Santos, San Andreas. The mission is a major turning point in the game.
The three feuding families of the Grove Street Families have come together due to Carl's efforts and Sweet decides to finally get back at the Ballas. Sweet also makes good with Carl and calls him his "running dog". He then orders everyone to get prepared and meet him under the Mulholland Intersection.
Carl leaves Sweet's house and receives a call from Cesar, who instructs him to meet up under the freeway north of Verdant Bluffs for some important news. At Cesar's urging, the initially hesitant Carl drives to the meeting point where Cesar is waiting inside a Bravura with tinted windows. There, they witness some Ballas members exiting a garage, followed by Ryder and Big Smoke, and finally Frank Tenpenny. Much to CJ's horror, Eddie Pulaski then reverses a car out of the garage, revealing the same green Sabre that was used in the drive-by in Grove Street that killed Carl's mother. Carl deduces that C.R.A.S.H. ordered the drive-by with the intent of killing Sweet, and have been working with the Ballas, Big Smoke, and Ryder to wipe out the Families and profit off the drug trade.
As Carl thanks Cesar for the information, he suddenly realizes that Sweet and the rest of the Grove Street Families are heading into an ambush. After ordering Cesar to take Kendl to a safe place, Carl races over to the underside of the Mulholland Intersection to prevent Sweet and the gang from being killed.
Upon arriving, Carl sees a deadly shootout taking place. He also sees that Sweet has taken a hit. Out of loyalty for his brother, Carl stays to hold off the Ballas hordes. Numerous Ballas members will come and shoot at Carl and the rest of the gang. Carl holds them off until the police arrive, causing the remaining Ballas and GSF homies to flee. Refusing to leave his injured brother, Carl surrenders to the LSPD.
Both brothers are arrested, with Sweet taken to a prison hospital upstate, and Carl taken kidnapped to Angel Pine in Whetstone by Tenpenny and Pulaski. Tenpenny explains what happened and what will happen next, before warning Carl to stay away from Big Smoke. Tenpenny also orders Carl to do what he wants from now on. His first task is to eliminate a former cop hiding on Mount Chiliad being guarded by the FBI.
