1Elsa, Anna and Kristoff were sitting in the dining room having dinner. Elsa was tired from a mixture of her Queen work and not feeling good. Her boyfriend Jack Frost was at a meeting with the other four guardians right now but would be back later.
"Elsa, are you feeling alright?" Anna asked.
"Yeah, just tired and not that hungry." she said.
"Ok." Anna said suspicious.
Then Elsa went to her room and laid down.
Back at the North Pole,
"Alright, Jack how are you and Elsa doing?" North asked.
"Good, she hasn't felt good lately but she's good. I've been busy at work as a guardian, seasonal and boyfriend." he said.
"Elsa isn't feeling good?" Tooth asked.
"Not really."
"That's too bad."
"How can you stand all this work?" Bunny asked.
"I don't have a clue." he said.
Then Sandy saw the moon lighten up. He started to try and get everyone's attention but as usual had no luck.
Jack felt the wind go off and saw Sandy trying to get their attention.
"What's up Sandy?" Jack asked getting everyone's attention.
Sandy smiled and then pointed up.
'Finally thanks to his element and the wind someone can figurate when I see the Moon calling us.' he thought.
"Ah Man in Moon! It's been a while, what do you need?" North asked.
Then a bottle came down and landed on North's hand.
"What is it?" Bunny asked.
"It is a potion that will allow Elsa to become immortal." he said.
"WHAT?!" they all said.
"It's going to make her and someone coming soon immortal. These two are presents for Jack." he said.
"OK then." Jack said.
"Let's just see what MIM is talking about another person is coming." Tooth said.
Jack sat there thinking.
"She hasn't been feeling well." he said thinking.
Then it hit him.
"She's pregnant! When my ma was pregnant with Emma she wasn't feeling well, tired and everything Elsa's got going on!"
They all sat there in shock.
"What do you mean your sister and ma?" Bunny asked for Sandy.
"Do any of you remember Jackson Overland? One of your oldest believers? How you have a light going all over the world and why I act like a kid?" he asked.
They all nodded.
"I'm Jackson Overland. I'm physically and mentally fourteen years old which is why I act so young. And a year after I became a guardian and getting to know you I turned into your new believer. I sacrificed my life for my sister when I was teaching-"
Then he looked at Tooth.
"Can you show them what happened years ago?" he asked her.
She nodded and had Baby Tooth go get it for him.
When she was back Jack put his hand on it and they went inside to see what happened.
They saw Jack and Emma standing there on ice.
"It's ok, it's ok. Don't-don't look down, look-look right at me," Jack said.
"Jack," Emma whispered," I'm scared."
That hit the other four guardians knowing that that's what Jamie said last year when he defeated Pitch.
"I-I know," Jack questioned noticing his staff only a few steps away from him. "But we're gonna have a little fun instead."
That got them to know that's how his center is fun.
"No we're not!"
"Would I trick you?"
"Yes! You always play tricks."
Jack managed a small laugh.
"Alright, well- well not- not this time. It's gonna be OK, you're going to be fine. You have to believe in me," Jack said shakily.
Hearing him say 'you're' going to be fine instead of 'we're' going to be fine got them to not like where it was going.
"You want to play a game? Let's play Hopscotch! Like we do everyday..." Jack trailed off and Emma managed a small smile.
"Yeah, it's as easy as one..." Jack took a step forward, towards his staff. "Two..." the ice cracked beneath him as he jumped forward. He wobbled, causing a giggle to come from his sister, "Three." Jack jumped onto the strong ice and grabbed his staff.
"Now it's your turn." Jack said. "One,"
Emma took a small hesitant step forward, wincing when more ice cracked.
"Two,"
Another small step,
"Three!"
Jack lunged forward and hooked his sister with his staff before flinging her behind him. The brown haired teen flew forward, where his sister used to be. Jack looked up and smiled at his sister. Underneath him, the ice gave out. A look of panic crossed Emma's face as Jack fell in the water.
"JACK!"
When they were back they looked at Jack and realized why he was so childish, good and protective with kids before he became a guardian and knew how to make kids happy and entertained, even though he lost his memory a part of him knew he had to protect them. He was a child himself.
"As you can see I was mortal and he made me immortal and a guardian because I gave my life for my sister. As long as I believe in you, even if I become your last light like Jamie you'll always be there."
They nodded and went back to their meeting.
Later that night Jack went back to Arendelle and went back to Elsa's room.
"Hi El." he said.
"Jack! You're back!" she said and gave him a kiss.
"Yup. Now how are you feeling?"
"Could be better." she said.
"Alright, why don't we go to bed and relax?"
She nodded and then went to bed.
