JoJo chills in front of Run's House, washing the sweet new ride he just received as an early graduation present. That's right, Rev Run gave his son a customized BMW!

The pressures and hardships of growing up are something everyone goes through, and Rev Run's kids are no exception. While playing a video game with Russy, Diggy is constantly being distracted by his phone. The text messaging and calls from girls keep interrupting the game, driving Russy absolutely bonkers. When Diggy kicks Russy out of his room to ask a girl out, Russy skulks off to his room.

Now that Angela and Vanessa have moved out of their New York City apartment and back into Run's House, it seems like they have a little more time on their hands. Sitting poolside, Angela begins to get tattoo fever, telling Vanessa she wants to get the name of their shoe line, Pastry, tattooed on her wrist. When Vanessa tells her she's crazy, Angela says maybe she'll get a star instead.

Even hip-hop legends have to unwind, and for Rev Run that means using his downtime to clean the pool in back of Run's House. When Justine comes out to tell him she has to run some errands, she reminds him that it's his job to supervise Diggy and his new friends, Brittney and Catherine. Run's face lights up when he hears Brittney's name because he knows she's rapper Ja Rule's daughter and he thinks the two would make a cute couple. Justine tells Run to behave himself or else he'll embarrass Diggy.

JoJo begins an internship at Phat Farm, where one of the designers makes his life miserable. Meanwhile, Rev buys an old-school arcade game to prove to Diggy and Russy that he used to be a video whiz.

Justine puts her Brown Sugar jewelry line on Home Shopping Network, and Diggy and Russy spend the night with their uncle Danny.

Russy gets picked on by his siblings, but his dad, who was also the youngest child in his family, teaches him how to deal with it. Meanwhile, Rev decides (after some soul searching) to invest in uncle Russell's latest business venture.

It's time for Team Blackout to start recording, but the guys are unsure about the producers they're supposed to work with and fear they won't get the hit they're hoping for. Rev tries to convince them that there are more important things than having a hit record. Meanwhile, Vanessa and Angela prepare to move to Los Angeles, and Justine gets great news on the adoption front.

As the fourth season wraps up, JoJo is mean to his sisters in the week before they move to Los Angeles. Later, in a tearful breakdown, he confesses that his behavior is just a cover-up of how much he loves them and how much he is going to miss them. Meanwhile, the adoption of Justine's new baby is about to become final, but it's uncertain if Vanessa and Angela will get to meet their new sister before they leave for L.A.
