So, Chapter 3. I'm kind of shocked at the response I've gotten for this story, so I'd just like to say thanks to everyone who's read!

I'll try and get chapter 4 out as soon as possible, but I have an Organic Chemistry exam and a German exam this week, so I might not be able to write it as soon as I'd like.

Jack opened the door to the Fenton house, closing it behind him with a sigh of relief. He didn't know why everyone here could see him, but it would take getting used to. Especially if they kept running away screaming.

"Hi, Jack," Jazz said, glancing at him. "We're getting ready to open presents. We don't have any for you, unfortunately. Maybe if someone had given us some notice." She looked down at Danny.

"Hey, don't blame me. It was a last minute thing. Not my fault."

Jack smiled and sat, laying his staff across his knees. "That's alright, I'll just watch. I need to talk to you afterward, though, Danny."

Danny nodded. "Sure."

A half hour later the two boys were sitting in Danny's room, Danny sitting on his bed and Jack perching on his staff.

"Ok, so what's up with all this fear of ghosts?" Jack asked. "I can't even go outside without someone thinking I'm a ghost and freaking out. They shouldn't even be able to see me, at least the adults, anyway, and now they think I'm a ghost."

"I don't know why they can see you," Danny said. "Are you sure you aren't a ghost? That would explain why you can fly." He thought for a moment. "No, that's not right either; my ghost sense didn't go off when you returned."

"Ghost sense?"

"Yeah, when there's a ghost nearby my ghost sense goes off. It's a good thing, too, because they're usually trying to kill me. Anyway, I don't know how familiar you are with ghosts, but most of them are bad news. Stay away from them, ok?"

"I can take care of myself," Jack said, remembering Pitch's nightmares.

"That's good to hear," Danny said. "I still don't know why Clockwork pulled you out of wherever you're from. Where are you from?"

"Nowhere in particular. I don't usually stay in one place too long, it gets boring. It mostly depends on what places need snow."

Danny rolled his eyes. "That didn't answer much. Tell you what, let's go see Sam and Tucker. Maybe they'll be able to figure things out."

"Who are they?"

"Friends of mine." He stood and opened the door. "We'll go out the front door so mom doesn't get suspicious."

"What about your dad?"

Danny laughed. "He's too busy playing with the new gun mom built him to notice."

Once out of sight of the house, Danny pulled Jack into an alley and changed into his ghost form. "We'll fly to Tucker's, it'll be quicker."

A few minutes later, Danny pointed at a window below him. The two of them swooped down, floating outside the window.

Inside, Jack could see an African American boy wearing a beret. He was fiddling with the wires of some sort of electronic device and was completely oblivious to the two boys outside his window."

Danny knocked on the window, chuckling as Tucker fell over backwards in surprise before coming to the window and opening it.

"Hi, Danny!" Tucker said. "Look what I got today. It's a new PDA. This one has almost two terabytes of memory, and a dozen new apps." He tapped the screen a few times. "Look, color-coded schedules!"

"That's great, Tucker, can we come inside?"

"We?" He looked past Danny, just now noticing Jack floating behind his friend. "Uh, sure."

"Tucker, this is Jack. He's staying with me. Apparently Clockwork's meddling again."

"Clockwork? Jeez, I feel sorry for both of you. That guy's a troll."

Jack laughed. "Nice to meet you, too." He looked around the room. There was a lot of technology here. He wasn't overly fond of technology, himself. He had been around a lot longer than computers, and besides, they tended to freeze up if he tried to use them.

"Are you a ghost?" Tucker asked.

Jack turned. "No, I'm a Guardian. It's a completely different thing. I think." Truthfully, he didn't know much about ghosts. For all he knew, they could be a lot like him. Except visible. And apparently mostly evil.

"What's a Guardian? Sounds like a rather pompous title, to me," Tucker replied.

"A Guardian protects the world's children," Jack said. "We were chosen by the Man in the Moon: me, the tooth fairy, the Easter bunny, the Sandman, and Santa Claus. We're all Guardians."

Tucker burst out laughing. "Dude, you can't be serious, those guys aren't real. Who are you, really?"

Jack pointed his staff at the floor beneath Tucker, icing it and causing Tucker to slip. "I'm Jack Frost," he said, frowning, "and the Guardians do exist."

Danny helped Tucker to his feet. "Jack isn't a ghost," he said, "but he's not human either. Apparently only people that believe in him are supposed to see him."

Tucker frowned. "Then why can I see him?"

"That's what we're trying to figure out," Danny said. "Can you call Sam and ask her to meet us in the park?"

"There's a park?" Jack asked, suddenly grinning.

"Yeah, it's a little ways away," Danny said, "but we should be able to talk without worrying about parents overhearing."

Sam arrived ten minutes later, and after introducing Jack the four of them began walking toward the park.

"So you're not a ghost, but you have ghost-like abilities," Sam asked as they walked.

Danny and Tucker tried to shush her, but she gestured around them. "No one's out here," she said, "it's Christmas."

"I guess," Jack said, shrugging. "I control snow and frost, and I can fly by calling the wind."

"But you aren't a ghost?"

"No."

"And Clockwork introduced you to Danny?"

"Yes."

"Ok," she said, apparently satisfied. Danny glanced over at her. He could tell she was thinking something. What, he couldn't be sure. He would ask her about it later.

They arrived at the park, the snow lying thick and relatively undisturbed. Jack laughed and ran ahead, scooping some snow up as he did. "Come on, talking can wait till later, let's have some fun!"

He threw the snowball at Sam, who dodged. The snowball went past her and hit Tucker. Feeling a strange tingly sensation, Tucker suddenly laughed, inexplicably happy. Scooping up his own snowball, he threw it at Danny.

They continued in this way for almost an hour, until finally they stopped, breathless and laughing.

Suddenly Danny's ghost sense went off. His mood immediately soured as their laughing was interrupted by a voice that he would know anywhere.

Hehe, cliffhanger. Now that introductions are done, things can finally start getting interesting!
