Percy Jackson walked down the Brooklyn street. He was alone. Annabeth was in San Francisco, and Grover and Jason were gods-know-where. So, for the time being, he was alone. Percy walked with his hands in his pockets, and fingering Riptide in his pocket. But he couldn't shake the feeling that something was wrong. That Chiron and Dionysus were missing one vital piece of the puzzle. He was trying to think of what it was. There was something they were missing. He should have felt perfect in peacetime, but after the Second Titan War and the Second Giant War were both over, he still didn't feel at peace. The word Titan made him think though. The Titans… They were all in Tartarus, though. Kronos and Hyperion he had vanquished himself. Iapetus thought he was a janitor named Bob. Krios, probably in Tartarus. Jason would know more about that. But there was something about the Titans that he didn't feel right about. He decided to ask his dad next time they saw each other. His dad. Titan. Demigod. Titan. "Oh my gods," he said aloud. He whistled for a taxi, panicking. How could he have not seen it sooner? The Titans had kids too. If the gods could do…. that…. then what made him think the Titans couldn't? "Half Blood Hill, Long Island," he told the driver. "Can do," he said. Percy sat in the back, heart pounding. Would the demititans be on his side, or not? And how could he not have realized earlier? And why was he so tired? His last thought before drifting off to sleep was Annabeth is going to kill me.
