Jack twirled himself around in North's chair. As soon as he'd feel himself getting dizzy, he'd stop for a couple of minutes and watch North work on his ice sculpture. Jack wanted desperately to ask a specific question, and he figured now would be the perfect time to ask - when he and North were left alone for a little while.
"North?" Jack spoke up. "What can you tell me about Pitch?"
North stopped his work and thought for a moment before continuing.
"Pitch was common man, like you and me," North began. "Had beautiful daughter who was his life. She was raped and killed; he went crazy and killed every man involved, including their own wives and children." North sighed. "He was executed, but was somehow brought back as the Nightmare King. He's been trying to take over the world with fear ever since." North thought for a moment. "Jack, why were you on floor when I came?"
"I woke up from a nightmare to see a pair of yellow eyes looking at me," Jack explained. "I got scared and fell off my bed."
North's eyes filled with worry, and he turned away so that Jack wouldn't see. He smiled seeing his ice sculpture of a grand, beautiful snowflake sitting nearby. He picked it up and carefully set it into Jack's hands.
"Not too long ago," North explained. "Manny spoke to me. He told me a boy of ice would be born within the next couple of years. He is to be of great help in defeating Pitch. We will make sure you two meet after this is all over, da?"
Jack nodded in agreement and handed the sculpture back to North.
Pitch paced back and forth throughout his lair, trying to figure out how to lure Jack away from the Guardians long enough to catch him.
"Don't you understand?" the familiar voice spoke. Yellow eyes appeared in the darkness. "You have to threaten something he loves. What is the most important thing in the world to him?" Pitch thought, but the voice spoke again. "His sister." Pitch looked at the eyes in shock.
"The Guardians will have my head," he protested.
"Oh no," the voice chuckled. "We won't be taking the girl. She must stay oblivious to the situation. No, I'm talking about illusion."
Pitch smirked, catching on.
And that night, a nightmare snuck into the Tooth Palace and made away with a very important set of baby teeth.
