Jack took his time to open his eyes. For some reason he had this intense headache and he didn't know what could have caused it. It felt like someone knocked a hammer on his forehead. Jack got up from his bed to rub his head.

Wait, his bed?

Jack's eyes shot wide open and he looked around. It was his room all right. That was weird. He didn't remember going to sleep last night. He didn't even remember walking to his room. Heck, he didn't even remember what happened yesterday.

That must have been one night.

Jack got up from bed, seeing he was in his blue hoodie and brown pants. With a stretch he let his arm out and his staff came flying in. Jack took another stretch before walking out of his room and to the dining room where everyone was already there, ready to eat breakfast.

"Morning," Jack greeted to his friends. "Oh, pancakes! My favorite!" He excitingly said, flying over to his seat and rubbing his hands together. "I can't wait to dig in!"

Everyone else was quiet. No one knew what to say to him. Yesterday was insane and seeing his sudden change of attitude not only question things, but made some of them scared.

"So...what are we waiting for?" Jack finally asked the group, seeing that they were all looking at him.

"Jack, are you feeling alright?" Tooth was the first to ask, leaning forward in her seat.

"I'm fantastic!" Jack yelled. "Why? I had the great sleep last night and you guys made pancakes for breakfast! What more could I ask for?"

"You were acting different yesterday," Bunny filled in, holding his boomerang in one hand just in case if he needed to attack. "You almost killed Tooth and tried to hurt North."

"I don't know what you're talking about," Jack said, going ahead and grabbing the pancakes to place them on his place. "I don't remember anything like that."

North smacked Jack's hands from touching the pancakes. "What do you mean?"

"What do you mean what do I mean?" Jack asked, setting his empty plate back down onto the table to look at the gang. "I don't remember anything that happened yesterday. All I know is that I woke up with this intense headache that won't go away."

"You don't know what you went through last night?" Tooth asked again, seeing the confusion not only on Jack's face, but everyone else's.

"No, I don't," Jack smacked his hands on the table. "And if it's something I should know then I want to know right now what happened."

Tooth, Bunny, Sandy, and North all shared the same confused look. They didn't know if they wanted to tell Jack what happened or not. Since he forgot that meant it was a thing of the past now, but if it was important that he had to know then maybe it was better that they did.

"Did I harm anyone?" Jack asked, seeing the room was dead silence.

"Almost..." Tooth answered honestly. "The worse damage you did was break one of my nails, but all is forgiven."

"Seriously...?" Jack questioned, confused on the gang was trying to say. "Okay...then what's the big deal?"

"You were gone for a week, mate!" Bunny shouted, getting up from his seat and smacking his paws on the table.

Jack and the rest were quiet, all looking at Bunny's sudden outburst.

"A week?" Jack repeated. "Are you sure?"

"Well, what was the last thing you remember?" North asked.

Jack looked down, giving that question a thought. What was the last thing he remembered?

Jack hummed. "Uh...I remember flying on my staff and you kicking me out."

North nodded his head and sat farther back in his chair. "Which was a week ago, Jack."

Jack shook his head. "Th-That can't be," he said. "Where was I then for a week?"

Sandy drew question marks on the top of his head. Tooth filled in for him. "You mean you don't remember?"

Jack shook his head. "No. I can't remember anything." He placed both his hands on the side of his head. "All I remember is what I told North."

"Jack, before you passed out last night you said a name," Tooth flew over and placed a hand on his shoulder. "You whispered, 'Elsa,' and then blacked out."

Jack looked at her for a moment and he only shook his head. "I can't remember who's name that is."

North sighed. "Do you remember breaking into my shed?"

Jack raised an eyebrow. "No," he said. "What shed?"

North got up from his seat and walked over to the glass window wall. He clapped his hands and the glass suddenly had the outline of the shed that North was talking out. North pulled out a stick from his pocket and stretched it to use as a pointer.

"This shed has been a secret I've been keeping from you for a while," North began explaining, pointing to the shed. "One of the Yeti's caught you snooping around last week and when I go to check it out," the screen changed to inside of the shed where Jack was sitting on the couch reading North's notebook. "There you are."

Jack slowly got up from his seat to walk up to the glass window. It was really him sitting on the couch reading a book. But he still couldn't remember!

"How you got in?" North asked. He shrugged his shoulders. "I'll forget you ever did." He stabbed the pointer into Jack's chest. "But what I won't forget is what you stole from me."

"Correction!" Bunny interrupted and they all turned to him. "Two things he stole."

"Thank you, Bunny," North nodded his head and turned back to stab Jack and re-said, "But I won't forget TWO things you stole from me!"

Jack turned to Sandy and Tooth, hoping they would tell him what was going on, but the two only shrugged their shoulders. They were curious on what North was going to say too for they weren't told this. God knows how Bunny knew first out of everyone at the table.

It was still quiet, everyone was looking at Jack, and North still had the pointer stabbed in Jack's chest.

"So...you're going to tell me?" Jack asked, moving the pointer away from his body.

North stood up straight, quiet as a mouse, and then screamed, slapping the pointer at the wall to get everyone to jump from their seat from the sudden noise. "MY NOTEBOOK!"

"And device!" Bunny added.

"AND MY DEVICE!" North also added, grabbing onto Jack's hoodie to pull him up off the ground.

"I don't know what you're talking about!" Jack yelled, throwing his arms and legs around as he was still stuck in the air. "What part of 'I don't remember anything' do you not understand?!"

North let go of Jack and he plopped down back onto the ground with a thud. North squatted down, scratching his beard while looking at Jack rubbing his bottom from the sudden landing.

Jack could have sworn North was about to slap him silly, but instead he laughed and lifted Jack up again, but this time in a huge bear hug. The other Guardians were confused at North's sudden change.

"North...can't...breathe," Jack struggled to say, feeling his lungs shut off. North still laughed, throwing him around in the hug.

"North, what is going on?!" Tooth flew up, helping Jack out of his hands and he fell to the floor again, but this time landing on his back. "Have you gone insane?!"

North controlled his laughter to get himself to stop. "The boy is in love!"

"What?" Everyone asked, including Jack who was still stuck on the floor in pain.

"He met a girl wherever he went to!" North yelled, lifting Jack up off the ground and onto his chair. "And fell in love."

"Is that true, Jack?" Tooth said.

Jack was quiet, trying to think, but there was nothing he could say. He still couldn't remember anything even if he repeated the name over and over again that North said he whispered before passing out yesterday. Nothing was coming to his mind.

"I don't know," he whispered, closing his eyes and looking down. Why was it so hard to remember? "Can I be excused?" He asked, but left anyways before anyone had answered. Jack grabbed his staff off the table and went back to his room.

Everyone also had looked down. They felt bad for taking Jack away from wherever he was. Not only that, but now he couldn't remember where he was. Who knew what the girl was going through now that Jack had randomly disappeared.

"What do we do?" Bunny asked North and he only shook his head. North didn't know either.
