Once Jack Frost finally arrived with the mane six, the Guardians were very glad to see him.

"Welcome to the North Pole, where you get the best toys from Old Saint Nick!" Pinkie shouted. "Wow. You got to be kidding me." Jack said in awe. "And you said you didn't want to come." said Rainbow Dash. "You're right. I take it back." said Jack. "Can't say no to the North Pole, can you?" Applejack asked.

"There he is, Jack Frost!" said North. "Hey, North. Long time no see." said Jack. "It has been a while, hasn't it." said North as he ruffles the boy's hair. "And look who's here to see you. The Tooth Fairy and The Sandman." Rarity introduced. "Hello, Jack. I have heard a lot about you, and your teeth." said Tooth. "My what?" Jack asked confusingly. Tooth opened his mouth to see that his teeth are pearly white. "Oh, you took care of them. They're so beautiful. Just like your ice and snow." she said in glee. "Ok ok, Tooth. Just give him some space." said Rarity. "Sorry." Tooth replied. "And don't forget Sandy." said Applejack, only to realize that Sandy fell asleep. "WAKE UP!" she shouted as she woke up The Sandman.

"So, the girls told me that you guys have a surprise for me. I mean, what did I do? Am I on the Naughty List?" Jack asked. "Naughty List? You hold the record. But, this is mostly about something else." North replied. "Here comes the surprise." Pinkie squealed. "What is it?" Jack asked. "What is it? I'll tell you 'what is it'! Because you are now a Guardian!" North shouted.

"SURPRISE!" the mane six shouted as music bursted through the room. There were trumpets playing by North's elves and Pinkie threw a lot of confetti with her party cannon. To Jack's reaction to all of this, he wasn't quite happy. What he did is that he raises his staff and blasted frost everywhere, causing the celebration to stop. Pinkie was spinning around with her party cannon in a stunned look on her face and said, "Touchie."

"What makes you think I want to be a Guardian?!" Jack asked in anger. North laughed at this and said, "Of course you do. MUSIC!" The music resumed playing by the elves before Jack interrupted them. "No music!" he shouted. "Jack, what's wrong? I thought you would be happy being a Guardian." Twilight asked. Jack sighed in annoyance and said, "As much as I appreciate being surprised, I don't want any of this."

"Of course you don't. Why? Because all you care about is snow all over the place." said Bunny. "Yep, its true. Besides, you don't want me. You're all of hard work and deadlines, I'm snowballs and fun times. I'm not a Guardian." Jack replied. "Maybe you should give it a chance. You won't be alone anymore." Fluttershy promised. "But, I have you Fluttershy. You and your friends." said Jack. "I know. But, you won't stay in Equestria for long. The seasons change and you only like winter." said Fluttershy. "And it's about time you do something for your life besides freezing everything." said Twilight.

"Let me show you something. This globe represents Equestria and each light you see is a pony." said North as he shows Jack and the mane six a large globe he watches over. "Oh wow. North, you didn't show us this before." Twilight said in awe. "This is how I watch over every pony in Equestria. Whether it is a child or an adult, good or bad, naughty or nice. We protect them, including you." North replied. "Wow." Rainbow Dash muttered. "But, what happens when the lights go out?" Applejack asked. "We Guardians will become weak and it will kill us. That is why we have to be believed in." North replied.

"That explains why Jack wants to be seen after all these years, right?" Rarity asked. "Wait, you're telling me that I've been waiting for 300 years of loneliness just to be a Guardian? That is not me! No offense." said Jack. "How is this not offensive? He doesn't care about anything." said Bunny. "Yep, the kangaroo is right." Jack replied in a rude manner. "The what? What did you call me? I am not a kangaroo mate." Bunny asked angrily. "If you're not a kangaroo, what are you?" Jack asked. "I'm a bunny. The Easter Bunny. People believe in me." Bunny replied angrily. They both stared at each other like they want to fight.

"That's enough! No one is fighting here! Bunny, leave Jack Frost alone." Fluttershy scolded. "Excuse me, Fluttershy. He does not care about anyone or anything. Not even you." Bunny replied. So, Fluttershy has no choice but to give Bunny The Stare. Bunny was confused at this and asked, "What is she doing?" "She's giving you The Stare. She does this to animals who misbehave." Twilight replied. Fluttershy kept staring at Bunny until the effects started to kick in. "Agh! Make it stop! Ok ok! I'll be nicer to Jack Frost, just stop staring at me!" Bunny shouted in agony. "Good Bunny." said Fluttershy as she pats him on the head.

Jack was laughing at the whole thing. "Jack, walk with me. Twilight and I have something to discuss with you." said North.

...

So, Twilight and North took Jack to the office where they can talk to him.

"Are you trying to talk me into being a Guardian? If it is, the answer is no." said Jack. "Actually, yes. It is about you being a Guardian and you will a great one." Twilight replied. "And, there's another thing I want to discuss with you." said North as he slams the door locked behind Jack so he won't get out.

"Who are you, Jack Frost? What is your center?" North asked. "My center?" Jack asked. "Yep, everyone has one. Including you. Take a look at my friends. Applejack has honesty, Pinkie Pie has laughter, Fluttershy has kindness, Rarity has generosity, Rainbow Dash has loyalty, and I have magic. These centers represent the Elements of Harmony and they remain in us forever. Now, it's your turn." Twilight explained. "I don't know what my center is." Jack replied sadly. "Well, you like to freeze things and throw snowballs at everybody." said Twilight.

"I still don't get it." said Jack. Twilight groaned in grief. "Don't worry, I'll handle this." said North as he brings out a Russian doll which represents him. "Is that you?" Jack asked. "Yes, and is this how you see me? Very big, intimidating, all that stuff. But, I'm also mysterious. And fierce. And caring. And my center is right here." North replied as he shows Jack a little doll. "You're a tiny baby." said Jack. "Yes, and what do you see?" North asked.

"He has big eyes." Jack replied. "Yes, eyes that represent wonder. That is my center. That is what makes me a Guardian. You will find your center." said North as he gives the boy the doll.

Suddenly, they saw Tooth zooming out of the North Pole and the mane six running towards them. "What's going on?" Twilight asked. Bunny and Sandy ran to them as well with worried looks on their faces. "We have a problem, mate. Trouble at the Tooth Palace." Bunny said in worrisome.

...

In a hurry, the mane six and the Guardians went to the place where North keeps his sleigh.

"Everyone, to the sleigh!" North shouted. "You have a sleigh? Cool!" Rainbow Dash shouted. "Oh no. There is no way I am going on a dusty old. Sleigh." said Jack as he saw the actual sleigh and it looks awesome.

It was bright red and has wings to help it fly better and was pulled on by bulky reindeer. "Oh my Celestia." Twilight muttered. "Ok, one ride and that's it." said Jack as he gets on the sleigh. "Everyone loves the sleigh." said North as he gets on. Once everyone is on the sleigh, they are prepared for takeoff. "Oh boy. This is going to be awesome!" Rainbow Dash squealed. "Oh bloody. Where are the seatbelts?" Bunny asked. "Don't be such a baby, it's gonna be fun." said Rainbow Dash.

And then, the sleigh took off. Everyone screamed like their on a roller coaster, except for Bunny. "I told you! I told you it was gonna be awesome! Woo hoo!" Rainbow Dash shouted. "You said it! I can feel the wind in my mane!" Rarity shouted. Pinkie was sticking her tongue out like a dog and was panting like one.

After the takeoff, the sleigh began slowing down as everyone took a breather. "Hey, Bunny. Check out this view." said Jack as he fell off. "Jack!" Applejack shouted. "North! He fell off!" Bunny shouted as he looks over to see if Jack was ok. It turns out that he was joking around and he just fine. "Aw, you do care." Jack said jokingly. "Oh, back off you little show pony." Bunny said angrily.

"And now, off to Tooth Palace." said North as he uses a portal to get there.
