It has been a week since Pitch has been defeated, but not all secrets were uncovered from Jack Frost, at least not by the other guardians.

North was checking on progress for his yetis until he felt a cool kiss of air nip at his nose. He knew who came to visit him. He looked up to see a pale teen with snow white hair, twinkling blue eye and a dark blue back pack on him.

"Ah Jack, what brings you here?" He asked as the pale teen landed.

"Not much. I was just wondering if you can give me a tour of the place, just in case I need something or find you if you're not in your office." North thought it was a weird request, but he also thought it was a good idea.

"Alright, let's begin."

As the tour went on Jack had a nervous face, but didn't show it if North turn around. The last stop was the infirmary, which Jack seemed to be relived to be at.

"Here we treat each yeti of sickness and injury." North began.

"What about the medicines for illnesses?" Jack asked and seemed anxious to get an answer.

"There are all in this closet." He opened the closet door to reveal many medicine bottles.

"Do you have anything for fevers, body aches, and dizziness?" Jack asked. North turned to him confused.

"Those things aren't good for me on sick days." He laughed nervously.

"Of course." North picked up a bottle off a shelf and handed it to Jack. "Go ahead and take it. We have plenty."

"Thanks North." Jack said when he placed the bottle in his back pack. North could hear the bottle clanking against glass as it was getting put in and was starting to get the feeling that Jack was hiding something.

"What do you have in there Jack?" North asked the young guardian. Jack's body locked up for a second.

"Um…just a…prank for Bunny. It's not done so don't want you seeing it." North was still not convinced of that, but decided to let it go. For now.

"I better get going, I have things to do. Thanks for the tour." And with that Jack flew out.

About an hour after Jack left Tooth came to North about Jack and found him pacing in the main room.

"North?" He turned to see the Tooth fairy "I'm sorry to drop in unannounced, but I need to talk to you."

"We do too." They turn to Bunny and Sandy coming out of rabbit hole.

"What is this about?" North asked them.

"I came to ask about Jack." They all said at once, startling each other that they came unaware that they were all on the same page.

"What did he do?"

"He came to me the other day and asked if I had a copy of a book for home remedies." Tooth stated.

"Really? He came to me asking if I had any plants that could help clear sinus pressure and last night he asked Sandy for a bag of dream sand." Bunny explained. "Did he ask you for anything North?"

"Yes, he asked if I had medicine that could help with dizziness, body aches and fevers." He told them.

"You don't think he's getting sick, do you?" Tooth asked worridly.

"I don't know, but Sandy gave him a small amount of sand and told him to come back to him today for a refill." Bunny told them. "We can follow him and see where he goes after the pick up."

"Maybe we shouldn't, Jack may have reasons for secrets." North tried to seem not interested in the plan.

"Come on North, if needs help we can give that." Tooth tried to persuade Father Christmas.

"Alright, alright, I'm in." He sighed in defeat, knowing that she is right. If Jack is in trouble then he needs to know that he can rely on them to help.

Later on in Burgess, Sandy was waiting on a roof top for Jack. The others were waiting for Jack as well just in hiding. They can sense that the air was getting colder which means that Jack is close by.

"Sandy! There you are! I've been looking all over for you." Jack yelled as he got closer.

Sandy didn't hold much of a conversation since he couldn't and the fact they wanted to help Jack with his problem. He was just making a few signs asking him why he needed the dream sand, but he used the same excuse.

"It's a prank, but it's not done so I don't want anyone seeing it. I'll see you later." And he took off.

What he didn't know was that there was a small tracking device that North had put in the bottom of the bag before the sand was put in so he wouldn't see it. About five minutes after Jack flew off the others decided to go into action. Jack was heading into the alleyway where he got captured by Bunny and the yetis. The tracker was going under large opening that lead to a large air con tunnel from the old subway system.

"Why in the world would he go down there?" Tooth asked disgustingly.

"That's why we're here, Sheila." Bunny stated. North got his swords and popped the gate like an old soda bottle. They all jumped down and saw that the tunnels were covered in a thick layer of frost proving that jack had been down there more than once. They traveled down the tunnel for about fifteen minutes with no sign of Jack.

"Is he even here?" Bunny complained with all of the stopping.

"Do you think he knew that we were following him?" Tooth commented. North continued on, looking down at the tracker in his hand.

"I don't know, but why would frost be everywhere if he wasn't-AAHH!" North was cut off when he fell through a large hole where the frost discontinued. The others went into a panic running to the hole all asking if he was okay.

"Get down here!" he called. The others were confused, but they jump down anyway. They saw the old entrance to the subway system power up and all. The place was covered in a light layer of snow and the style was probably around from the 1950's. The place was very clean proving that someone has been here even though every single entrance was supposedly covered by cement.

"Why was this place shut down?" Tooth asked keeping her voice low.

"I think it was due to faulty conditions." Bunny answered.

They heard things moving around and a door, from one of three remaining cars, being closed. They followed the sound to a faintly lit car. They opened the door quietly and saw an old fashion style lantern lit like lamp. On the long cushioned benches they saw a boy that was about the age of eight or ten, with a pillow and a blanket barely covering him, sleeping in discomfort, with a pale face, a red nose, and very red cheeks. The guardians were shocked that a child was in a place like this, but really shocked them was how much this boy looked like Jack. He looked like a mini Jack, the only difference was his hair because it brown.

Tooth fluttered over to the boy and looked at him worriedly. Baby tooth, who had been with Tooth the entire time, flew to the boy and put her hand on his head and pulled back in shock. She squeaked rapidly causing the boy to stir a little. The other shushed her down and she calmly explained again.

"The boy has a very high fever." Tooth translated whispering.

"He probably can't afford a doctor." North figured.

"Should we get him out of here?" Tooth asked.

"That would be the right thing to do. Let's get him out of here." Bunny stated, just then they heard a low growl coming from below the boy's bench. They saw a grey and white wolf like dog in protective mode. The growling and snarling was so loud that it woke the boy up.

"Gizmo? Gizmo, what's wrong?" The boy asked half asleep and with a very stuffed nose.

"This has a very strange feeling of Déjà vu written all over." North commented.

"Don't worry this won't end like it did with Abby." Bunny took another step which wasn't a good idea. 'Gizmo' was just about to pounce on its prey which ended up Bunny using the same face with Abby.

"Gizmo, stop!" He stopped in his tracks. They all turned to Jack standing at the door that lead to the next car, with an ice pack in hand and the bag of sand. Gizmo walk towards him, Jack knelt down and whispered something in his ear and with that Gizmo walked calmly back underneath the boy.

"Guys, what are you doing here?" He asked.

"We were worried about you." Tooth explained. The others nodded in agreement while Bunny rolled his eyes. All of a sudden the young boy started to have a coughing fit. Jack rushed towards him, gave him his water bottle to drink that was nearby. He held him close; rubbing his back as the coughs slowly subsided.

"It's okay Jesse; they won't hurt us, just try and get some sleep." He told him, running his fingers through his thick brown hair.

'Jesse' nodded in understanding. He lay back down on his pillow and pulled his blanket over him. Jack put the fresh ice pack on his head and got a handful of sand and sprinkled it onto Jesse to help him sleep better.

"Jack what is going on?" North asked. His tone and face were sternly and Jack sensed that the other demanded an answer as well with or without saying anything.

"Let's talk in the other car." So they walked in the other room quietly so they wouldn't wake Jesse, Bunny was still cautious of Gizmo, who was still wide awake.

"Don't worry; he won't hurt you now unless I tell him to Bunny." He reassured him and they all stepped into the car to get the story they never thought they would hear.
