Unfortunately, due to the internet, word had got out over WrestleMania weekend that Brock was returning so when Brock came out to interrupt John Cena, the crowd were already chanting his name. This still didnt nullify the return though as the crowd went crazy. Brock circled the ring, entered it and promptly hit the F-5 on the Doctor of Thuganomics. A new beast was in town. The following week, Cena came out to answer the smackdown only for Lesnar to again interrupt and the crowd knew what they wanted o see. Cenas thank you for the F-5 was a slap in the face which was promptly returned with a takedown, elbow to the head and punches to the ribs. As the locker-room emptied, it was obvious that this was a very different fight to Cenas usual punches and when the camera showed Cenas bloodied mouth, it all of a sudden felt very real. https://www.youtube.com/watch?v=GnnxMwM32Nw The weeks leading up to Extreme Rules were great as it felt like a rivalry that could explode at any moment and, as with some of Brocks best work in the WWE, it felt like it wasnt a work at all. What this did was not only confirm Lesnars potential dominance, it also helped Cena look stronger than he had in years as the two prepared to lock up at the next PPV.
