Nico and Bianca: An Alternate Ending

Demigods?

So today, these 'demigods' Percy, Annabeth, and Thalia showed up at my military school, Westover Hall. Our friend, Grover is a saytr. And most surprising, my brother, Nico and I are demigods. Our mean principal, Dr. Thorn, is a manticore. I'll explain in more detail.
I was with Nico at a school dance. We didn't have dates, because military school boys are weird, so we were sitting on the bleachers together playing Mythomagic. Sometime during this, the demigods arrived. Dr. Thorn threatened to kill us if we did anything to him. He didn't seem quite...human. Especially not during this. I took Nico's hand and brought him outside so we could escape. The demigods ran outside to kill Dr. Thorn. One of them, Percy, tried to get us to jump off a cliff. He's weird...Anyway, one of the demigods, Annabeth, jumped on Dr. Thorn's back. Sadly, he fell off the cliff with her after this group of girls, each armed with a bow and arrow, attacked him. One of the girls came over to us. "I am Artemis, goddess of the hunt. These are my hunters." Another girl stepped forward. "My name is Zoë Nightshade. I am a hunter. You two are half-bloods. One parent is a mortal and the other is an Olympian." Of course, I didn't know about the gods. So my response to this was, "Like...an athlete?" "No, one of the gods." Zoë replied. After some silence, Nico yelled, "COOL!" Then he started asking about attack power and other stuff from his Mythomagic game. "This isn't Mythomagic! This is real! And the gods aren't." I explained. "They are. You are coming with us to Camp Half-Blood." Percy said. "Cool, let's go!" Nico smiled. "No!" I said. "Of course, there is another option. Come with me, Bianca di Angelo." Zoë said.
She told me all about the hunters. "Do you want to join the hunt?" she asked. I looked at Nico. "No, I can't. I have to take care of Nico."
