As Caesar reels from the punch, Smoker remembers that before Law freed him, he ordered Smoker not to touch Caesar since he still has his heart. Smoker leaves to go find Vergo.

As Luffy begins the second round of their battle, Caesar demands to know why Luffy is trying to capture him which he explains is part of Law's plan. Caesar admonishes him, warning Law cannot be trusted but Luffy retorts that's for him to decide.

The two fight with Luffy landing a few solid hits. Caesar tries to suck the oxygen out of him but Luffy manages to get out of range of the powers and attack from a distance.
