The Color That Rainbows Forgot

It's been a week since our little confrontation at the school. They journey to New York was one of the first times I've spent an extended period of time without Sinha. That thought reminds me of something Percy said.
"Hey didn't you say something about Sinha and two other demigods?" I ask out of curiosity. Annabeth stop walking in front of me and I have suddenly stop to avoid running into her back.
She hesitantly responds "I guess we did. Well we had planned to bring them with us, but your antics caused us to bring you back immediately." The cool breeze blew through the forest as we continue our trek through the darkness.
"So are you going back to get them?" My voice echoes through the silent woods. "Unfortunately, we have to, but since this is your fault you'll be doing our chores while we're away." Jason answers.
Before I could answer the smell of smoke filled my nostrils. The words "What's Burning?" Come out of my mouth. "That is what the Lamens call a campfire." Piper giggles. The sound of uncountable numbers of people beings to rise up in the distance.
"Your camp has campfire songs?" I yawn. We walk under an old, wooden Sign reading "Camp Half-Blood". The Sound of voices and aroma of burning wood continues to grow stronger with each step.
As soon as we reach a large clearing everyone comes running over to greet their returning heroes. One of them, a centaur, has a particular interest in me.
"Chiron, right?" I shout over the cheering of hundreds of demigods. "Everyone calm down. We have a newcomer to greet." Chiron commands. "Umm Chiron why couldn't we just leave him and bring the other three, or at least take him by force because now we have to make another trip?" Percy immediately questions.
"Firstly, another trip won't kill you, hopefully. Secondly, I've been lying to you." Chiron responds calmly. Jason blurts out "Lying to us?" As if he were thinking aloud. "Unfortunately, that has been the case." Chiron confirms.
"What have you been lying about?" Annabeth pesters. "I'll be honest, I'm glad you guys got Seth to come back without incident because if things got violent. You wouldn't have stood a chance." Chiron lets his words sink in before continuing "Seth isn't a Demigod."
Whispers erupt around us. "What is he then?" Percy quickly ask. "I'll answer that we you bring me Sinha, I believe his name was and Frank, Hazel, Leo, and Calypso return with the others." Chiron Explains.
"I'll let you rest tomorrow, but the next day you five are off back to get Sinha." Chiron announces. "Why is he going?" Jason complains. Chiron seemed to have expected that question because he answered immediately with "Because I understand he is friends with him. Now off to bed."
