In Los Angeles' Chinatown district, Griffin enjoys a bowl of noddles when he notices a child playing with an action figure of Knifehead and a Ranger. His meal is interrupted by a tattooed man, who knocks his bowl of noodles from his hand. Angry, Griffin attacks the man, knocking him down with a single punch.
He notices a a man in sunglasses watching him and mockingly asks if "enjoyed the show". The resteraunt owner demands that Griffin leave his establishment, and Griffin insults him, saying his soup tasted like dishwater. Spotting the action figure of the Ranger on the floor, Griffin leaves the restaurant and tries to return the toy, only to find the child nowhere in sight. The man he knocked out attempts to attack him again, but Griffin knocks him down and leaves Chinatown.
On his Motorcycle, Griffin drives all the way from Los Angeles to Santa Monica. He meets his co-workers, Verma, Dwayne, Pena, and Hawk at a sealed off scrapyard they mean to enter on the order of Mech Czar. Griffin assures his co-workers, who believed he wouldn't arrive in time, that he wouldn't leave him under the supervision of Pena. He offers Dwayne a weapon that allows him to burn through the wall of the sealed scrapyard. When Verma reminds him to wear his HAZMAT suit, Griffin dismisses the notion, and enters the scrapyard.
Inside, Griffin is surprised to find the remains of other Jaegers fallen in battle. He warns them to take only want Mech wants them to retrieve and not to be greedy. As he tells them to look out for drones that will be searching for them, they attacked by men employed by Giovanni Capello. Griffin attempts to lead his group away from Capello's men, but he happens upon the remains of Vulcan Specter and remembers the battle against Mutavore. One of Capello's men mange gain the advantage over Griffin during his distraction and knocks him unconscious.
- According to Stacker Pentecost, all Mark-3 Jaeger pilots save Raleigh Becket, were killed. The introduction of the character Joshua Griffin, a Mark-3 pilot, may be a likely oversight.
