The gang stops Ballas from getting in to Grove Street
Sweet, CJ, Ryder and Big Smoke all meet up. Big Smoke decides that he's hungry, so the group all go to a local Cluckin' Bell for some food. Yes, this is the iconic Big Smoke order mission. CJ asks about his mother again, and Ryder mentions they were after Sweet with a Green Sabre.
As they're leaving Cluckin' Bell, Ryder notices some Kilo Tray Ballas are scoping them out in a car and heading towards Grove Street. Now the gang must get rid of the car and the Ballas inside. Once all Ballas has been eradicated, they all head back to the Grove.
While the Ballas were on their tail, all Big Smoke did was eat, which CJ and Sweet question. CJ takes Big Smoke back to his house and asks why he moved away from Grove Street, stating he got some money in a will, but Grove Street will always be like home to him.
