Colin is an employee of Kandy Welding Co.
Colin celebrates the successful heist of Todd Alquist's money along with Neil Kandy and the rest of his crew by ordering prostitutes and doing cocaine. When the prostitutes leave, the men are confronted by Jesse Pinkman, who asks for $1,800. After dueling Neil for the money and successfully killing both him and Casey, Jesse orders Colin, Kyle and Sean to hand over their driver's licences. Colin pleads with Jesse that he has children, but the latter is unsympathetic. From the driver's licences, Jesse learns their names and addresses, and threatens them that in they tell the police anything about him, he will come back and kill them. The men then flee the compound, after which Jesse torches it to cover up the murders of Neil and Casey.
