Sean "Sweet" Johnson is CJ's older brother, living in single floor home just next to the Johnson House. Sweet also has an unnamed girlfriend, who only appears one mission. After the death of his brother, Brian, Sweet blames CJ for the murder of their little brother, prompting Carl to leave Los Santos. As "shot caller" of the Grove Street Families, Sweet remained in control of the gang while Carl was away, albeit in a sorry state. Throughout the storyline, Sweet remains caring and dedicated to his family, gang, and neighborhood.
After his return to Los Santos, CJ aids Sweet and the rest of the gang in restoring the GSF to its former glory. This would end in the middle of the storyline, however, when Sweet was badly wounded and jailed for a period of time, after Sweet and a portion of his gang was ambushed by the Ballas, and were subsequently arrested by the police; with some members also killed.
After recovering in a prison hospital, he is placed in prison between two psychopaths. In the left cell a child killer, who wants to rip his throat out. In the cell to the right of him, a white supremacist, who wants to eat his heart.
Sweet was released from jail later in the game, after Mike Toreno had agreed to Carl that he would arrange for Sweet's release in return of a favor. Sweet would then return to Los Santos, and rebuild the GSF's dominance in the neighborhood again, for good. Sweet's carnumber is GROVE4l.
It is suspected, that due to the familiarity with the film Boyz N the Hood, Sweet is a copy of character Doughboy. Sweet was voiced by Faizon Love.
