The best bet for a return to the streets is if the end to the last movie was a memory from Dom's past, and now it would be his job to raise is now teenage son by keeping them in the Street Racing scene he can save his son the pain that Dom is torture by ( flash backs to scenes that have never been seen to the endings of all of his crew ) for the purpose of protecting the last of his family and his son from all the pain and suffering caused by leaving the Racing World behind so that his son can have a future in the chances of going pro for is son is the only way to save him from losing all of his friends and family that are left and the struggles of raising a son with all the evil in the world right around them lurking in the shadows of the night just waiting for the chance to destroy Dom's new life. The fear that all is lost is a constant reminder of how quickly life can change for someone in the streets hidden from the eyes of the world they cant know that he's alive because if they find out it will be the end to the future of his son and the death of his family Name.
