Basically, Percy was conflicted. The young demigod had just been to Tartarus and back, literally, with his girlfriend, a titan whose memory had been erased (Percy's fault), and a skeletal ghost cat that could turn into a very alive saber tooth tiger. Small Bob. The two that had not plummeted through an ancient floor for nine days straight had stayed behind, making sure that Percy and Annabeth would be brought back to the mortal world to meet their friends and continue on their quest. Their sacrifice, along with Damasen's, had made it that more important for them to succeed in defeating Gaea and saving the Earth, from the Earth...
Percy would remember to say hello to the sun and stars for Bob, he would never get the chance to see them again. Before the titan janitor had started helping the demigods, Percy had pushed him into the River Lethe, and convinced him of his new, kind and helpful self, he never checked on the friendly creature again. But Nico did. With all that they had endured in the prison land below the Underworld, Percy was more than relieved to be back in the company of his friends and in the mortal world, but there was another problem than just guilt on his mind, the Argo II was sailing to Greece to battle an army of giants, even if the doors were closed it would be nearly impossible to win that fight. The prophecy was coming along to, and Gaea had been speaking for weeks about two half-bloods having their blood spilt to awake her. To Percy, dirt face was awful enough asleep and stirring, he couldn't imagine her at her full power.
Reyna, who Percy, as a former praetor of the 12th Legion, had worked with and respected, was now shadow traveling to Camp half- blood, with the Athenian Parthenon to settle the rift between the Greek and Roman camps, maybe even the gods identity problems and schizophrenia. It was such a long shot, but it had to work, and Coach Hedge, Nico and she, had to arrive at Long Island before Octavian attacked with full force. Both of Percy's homes were about to be torn apart, he had to count on Reyna more than ever. He thought about Grover, and Chiron, and everything else back in New York, including his mother and he felt terribly homesick.
Percy was alive, which was good, but how long would that last? How long would that last for any of them? He couldn't help but feel like one or more of them were about to die in Greece, they've all had so many close encounters, and their vessel had seen better days, but he had faith in his team. And when he didn't he told himself that he needed to pretend that he did.
"What are you doing Seaweed Brain?" Annabeth had to ask, she would've just left him to his thoughts, but to tell the truth she also needed to talk to him, they had been so dependent on each other in Tartarus, it made her worried when they were apart. She walked towards him.
"Thinking about how I had never thought to write with it," he glanced up at her and rolled riptide around in his fingers, "the pen is supposed to be mightier than the sword you know, but when the pen is the sword…" he took her hand. She looked out at the sea, it looked never ending, and their future, even less uncertain.
