Percy groaned. When does Mr. D not want him? He got from the table and followed Chiron to the Big House. Mr. D was sitting on the deck with some satyrs playing gin. Percy approached Mr. D with Chiron. "Sir," Chiron spoke. Mr. D snapped his head up immediately.
"What?" Mr. D looked down at his cards and smiled to himself. The satyrs shifted uncomfortably in their seats.
"I brought Mr. Jackson, as you wished." Chiron said, gesturing Percy to come forward.
"Ah yes, Peter Johnson." Mr. D grumbled, quickly putting down his hand.
"Its Percy Jackson, remember?" Percy rolled his eyes. Mr. D always forgot his name, even though he's known him since he was twelve.
"What do half-bloods say these days? Whatever?" Mr. D said, not looking up from his cards.
"What do you want now, Mr. D?" Percy asked.
"I don't want anything from you," Mr. D sneered. "I just have a message for you from you father."
"Dad?" Percy asked quietly. The last time he spoke to his father, was when the Half-Bloods defeated Kronos and his followers last summer. "What does my father want?"
"He wants you to go to Olympus so he can tell you this mission he wants you to do." Mr. D said impatiently. "Something about finding your sister in the Underworld."
"My…sister?" he said confused. "I don't have a sister."
"Don't ask me," Mr. D said. "Ol Fish Face just wanted me to tell you. You'll leave tomorrow, go to Olympus, come back to camp to pick who you want to go with, and then set out for wherever."
Chiron pulled Percy away from Mr. D. "Thank you, Mr. D," Chiron said. "I'm taking Percy back to his cabin."
"But…" Percy said, still confused about the whole sister thing.
"No buts Percy, we need you up early for tomorrow. I already told your instructors that you'll be absent today." Chiron said whisking Percy to his cabin. Percy stopped at the doorway. "Chiron," he said. "Do you know what's going on? What did Mr. D mean about the whole 'sister' thing, and why does Dad want me so bad?"
Chiron sighed. "Percy, all will be explained tomorrow. Now just relax today, we need you good and ready in the morning, alright?"
"Fine," Percy muttered and walked inside. He spent the whole day reading Tyson's comic books and pacing around. When Tyson came back from his activities, Percy left the cabin during dinnertime. He went to the shore of the camp and sat on a familiar flat stone that he'd always sit on.
"What did Mr. D mean about my 'sister'? I don't have a sister. What's Dad trying to say?" he asked to himself. He skipped a few stones and walked back to the cabin. Supper was over and he found Tyson playing with his animatronic horses.
"Percy!" Tyson looked up from his horses and shouted. He raced to the door and gave him a big bear hug.
"Hey Big fella, what's going on?" he said walking through the door. Tyson released his grip and sat down on the floor. "Playin' with my horsies…" he said softly, tinkering with one of the horse's reigns.
"Is something bothering you Big guy?" Percy asked.
"Annabeth is angry with you," he said, not looking up. "She wants to know why you're being a…. A 'Jerk'." He said putting Jerk into air quotes.
"Things have been rough between me and her…," Percy said with a sigh. "But we'll get over it, right?"
"Right Brother!" Tyson smiled.
"Good," Percy grinned.
"Something else Brother…" Tyson asked after a few minutes.
"What?" Percy asked not looking up from his comic book.
"Are you seeing Daddy tomorrow?" Tyson questioned from the floor.
Percy said quietly, "Yes," trying not to upset Tyson. Tyson sprang to his feet. 'Why?" he yelled, obviously upset that Poseidon didn't ask for him too. Percy walked up to Tyson and patted him on the shoulders.
"I don't know why Tyson," he said. "But I've got a mission and as soon as I'm done talking to Dad I'm taking you with me, Ok?"
Tyson broke out into a huge smile. "Ok!" he said and crawled into bed. "Going to help Percy and Daddy! Going to help Percy and Daddy!" he sang to himself from under the covers. Percy shook his head with a grin and went to bed himself.
