I thought this would be a cute idea since I heard that Jack is supposed to look like Nightlight. This is set the Halloween after Jack becomes a Guardian. If they do make a second movie of Rise of the Guardians I hope they bring Nightlight, Katherine and everyone else who lives at Santoff Claussen.

"Do I really have to wear this Sandy? It's too tight." Jack whined as he tugged on the outfit Sandy made him put on making Sandy roll his eyes then nodded, crossing his arms across his chest and Jack sighed. "Fine but it had better be just for tonight I don't even know where you got an outfit this tight and don't want to know. By MiM how can he even breathe in something so tight?"

Sandy chuckled as he formed a Jack-o-Lantern above his head making Jack groan. "Yes I know I agreed to join you in dressing up for Halloween but I never thought you would choose such a tight outfit for me to wear or how you convinced MiM to change the appearance of my staff."

Taking a step back to look over the costume he picked for Jack to wear Sandy nodded with satisfaction then went to get his own costume on before he and Jack could head out for the Pole and the Halloween party North was holding leaving Jack alone to take a glance in the mirror behind him.

"I don't even know who I'm supposed to be Sandy." Jack called out as he checked out the costume Sandy had forced him into, tugging on it.

Later that night Jack nervously entered North's workshop with Sandy not knowing how the others would react to his costume especially the other immortal boy he was supposed to be dressed up as, it being Sandy's idea, and fidgeted as they joined the small group of Guardians.

Bunny spit out the carrot juice he had just took a swallow of as he did a double take upon seeing Jack, who scowled at him with a muttered, "Shut up Kangaroo. It was Sandy's idea I dress up like him." Knowing Bunny would hear him then a smirk spread across his face and he sidled up to Bunny.

"See something you like?" Jack purred into Bunny's ear in a teasing manner then burst into laughter as his ears fell down against his back and he shoved Jack away from him.

"Rack off you bloody show pony." Bunny snapped before walking off to talk to a Guardian Jack had yet to meet, a young woman who was visiting with North, Nightlight floating next to her. Before he could follow Bunny though Jack found himself looking into curious purple eyes as Tooth took in his costume, making Jack laugh nervously as she did.

"Nice costume Jack, if I didn't know better I'd say Nightlight had a twin. Oh you have to let me get a picture of the two of you together." Tooth squealed as she grabbed Jack's hand and dragged him over to where Nightlight was even though Jack tried to protest when she did, shoving Jack next to Nightlight as she snatched the camera North was holding out of his hand and quickly took a picture before Jack could move.

The young woman looked from Jack to Nightlight, astonished on how much the two of them looked alike. "You must be Jack it's a pleasure to finally meet you. North has told me a lot about you. Oh, forgive me I'm Katherine."

Jack grinned, holding out a hand for her to shake. "It's nice to meet you as well Katherine though I must say I thought that Tooth was the only female Guardian in the group." He remarked as he eyed North and Bunny.

After the party Jack flew toward Burgess as the sun was going down, having promised Jamie he would join him, his friends and Sophie when they went Trick or Treating, managing to talk Sandy and Nightlight to join him. Landing Jack grinned as soon as he saw Jamie's costume. "Nice costume Jamie, who are you supposed to be?" He joked.

Jamie turned around at the sound of Jack's voice, a smile on his face, and answered. "I'm you… well you when you were still alive." Jack walked around Jamie, having told the boy what he had looked like when he was human.

"Looks like you got the outfit perfect, in fact you look just like I did at this age Jamie." He commented making the child beam.

"I do?" Jamie asked and Jack nodded, smiling when Jamie hugged him quickly returning the hug as Sophie came running out the door in her costume, Baby Tooth flitting around her in excitement. Jamie notice Sandy and Nightlight just then. "Hey Sandman and uh Jack's twin." He greeted making the three Guardians laugh.

"Jamie this is Nightlight, he's nearly as old as Sandy and was one of the very first Guardians, Nightlight Jamie and he's my first believer." Jack introduced and Nightlight smiled at Jamie, bowing slightly as he did.

After Jamie's friends arrived and everyone was introduced to Nightlight the group set out to get candy as they wondered the neighborhood until they had hit every house then slowly one by one the children returned to their homes for the night until it was only Jack, Sandy and Nightlight left.

Nightlight and Jack sat on the roof watching Sandy as he made sure the children had good dreams that Halloween night.
