The overly cocky part of Percy's brain wanted to chide back that Magnus couldn't handle more effort. Which would have been a bold statement, given that he didn't actually know. He did appreciate the call out though, and the corner of the left side of Percy's mouth went up slightly. The jump had been a good one, admittedly, though being so far it did lose a little of the umph.
"What do you think this is, the film Troy?" Except that the scene did somewhat remind Percy of that movie. He was walking around Magnus now in the same way that Achilles in the film had done to Hector. He was trying to find the perfect opening, because at the moment, Percy couldn't tell if Jack or Magnus were in control. Once again, Percy swung and when the blades met, he directed the both of them around in a circle. Once Magnus had his back to the water, Percy shoved at him forcefully, then swung threee consecutive times, pushing his opponent closer toward the water's edge.
