On the May 7, 2012 episode of "Raw", Heyman returned to the WWE as Brock Lesnar's legal advisor. When Lesnar left, Heyman aligned himself with CM Punk on the September 3 episode of "Raw" when he was seen driving a car which Punk entered. He managed Punk until Money in the Bank when Heyman turned on Punk by smashing him with a ladder while he was climbing up another ladder. He returned on the December 30th edition of Raw and returned to being the manager of Brock Lesnar.
