RotG and Dick Grayson

Jack Frost froze one of the nightmares in front of him, causing it to explode into a cloud of black dust. He flew forward as Toothiana took out another, only to become surrounded by a group.

"Thanks Jack!" she shouted over her shoulder as she flew to destroy the nightmare closest to the young boy's window. Jack turned and dissolved another nightmare with his staff as it went to attack North, who was slicing through as many nightmares as he could with his swords.

Jack flinched as Bunnymund dissolved a nightmare with his boomerangs, almost hitting Jack as they returned. He flew over to help Tooth protect the boy, ending up with both of them fighting back to back as they floated outside the young boy's window.

Jack froze the last nightmare and turned to his fellow Guardians.
"Where's Pitch?" he asked, seeing no sign of the boogeyman they had been sent to stop. North shrugged and searched the area for any traces of his existence.

Jack frowned and muttered to himself "Why would Pitch target this kid?" as he sank to the ground beside the boy's bed. He leaned on his staff and looked at the raven-haired boy they had just defended. He looked about nine years old, short and skinny with eyes puffy from crying.

"He was an easy target" Pitch Black answered as he appeared at the end of the boy's bed. Jack turned and raised his staff, noticing how the other guardians had done the same.

"I had to get you all together somehow. So I picked an easy target, a child who is clinging desperately to his belief in the Guardians because it's all he has left." Pitch smirked as he said it, proud that his little plan had worked.

Sandy was the first to react, using his whips to grab the boogeyman's wrist and throw him out of the window they had all just flown through. Sandy turned and nodded to Jack, who flew out of the open window and froze Pitch, before returning to the boy's bedside.

"What do we do with the Pitch-sicle outside?" he asked North, who chuckled.
"We could leave him out there to defrost" Bunny suggested. Sandy was creating pictures again, but this time Jack understood, saying that he would take care of him.

With a nod from North, Sandy flew out of the window. He paused a few feet away and waved his hands in the direction of the young boy, the dream sand flowing from them and surrounding the sleeping child.

Jack watched the dream with a smile, watching as the raven haired boy smiled as he dreamed about the circus. Jack watched the big top dissolve and become a family on the trapeze.

He frowned as Tooth fluttered in front of him and delved under the boy's pillow, pulling a tooth out and placing a quarter underneath.
"Knocked out as he fell from the trapeze" she whispered to the assembled guardians watching Sandy deal with Pitch.

Jack watched Pitch fly off into the distance and he flew out to join the small man, casting a sad glance at the young boy as he left. He waited in North's sleigh, laughing as Bunny dropped out of the window and tripped over on a rock.

"That's not funny" Bunnymund said to a laughing Jack.
"No" North said as he pushed Bunny into the sleigh. "It was hilarious" he finished in his russian accent, joining Jack in laughing.

"Guys" Tooth interrupted "Can we go to Tooth palace? I think we'll find out why Pitch targeted him if we put this in it's box" she held the tooth in front of North's face and he nodded, pulling on the reins as he pulled a snow-globe out of his coat.

He shook it and threw it in front of the sleigh, creating a magic portal for the sleigh to fly through. The entire sleigh shook as it landed on one of the platforms in Tooth Palace, making Bunnymund turn a pale shade of green, and everyone got out of the sleigh.

Toothiana flew off the moment the sleigh landed, returning a few moments later with a canister full of teeth in her hands. She placed the tooth inside it and pressed the diamond design on the top as she closed it.

The scenes shifted rapidly, travelling from town to town with the same Big Top, flying through the air at the top of the tent without a net, training on the trapeze. She watched as he fell off the trapeze and knocked his tooth out, his mother dismounting and shouting "Dick are you alright?!" over and over again.
Dick stood up and grinned at her, holding out the tooth for her to see.
"You'll have to put it under your pillow after we finish the show tonight" she told him.

The scene changed again to the nights performance. Dick watching from the sidelines as they all fell without the net, then being handed to social services and eventually ending up in the care of a man named Bruce Wayne.

Tooth pulled her hand away and started to cry, shocking all of her friends around her. Jack pulled her into a hug as she stood on the ground and dropped the canister full of teeth.
"What happened Tooth?" North asked, making the fairy look up at him.

"I know why Pitch thought he was an easy target" she told the large man, who motioned for her to explain. "Pitch said he was holding onto his belief in us because it's all he had left, he wasn't wrong."

"What do you mean?" Jack asked, picking the canister off the floor and handing it to Bunnymund as he spoke. The Easter bunny took the canister and touched the design, pulling away a few moments layer and handing it to North, rubbing away a tear with his paw.

The teeth were passed around the guardians until they were passed to Jack, who shook his head and put it on the floor, unwilling to put himself through whatever was making the rest of his friend's cry.

"He watched his entire family die Jack" Tooth explained to him.
Jack's eyes widened as he put the pieces together.
"In a trapeze accident" he asked.
"How did you know that?" North asked.
"He was dreaming about a circus and trapeze artists. And I heard about it when I flew over here earlier. Haly's circus, an accident caused the trapeze rope to snap when they were performing without a net, orphaning the nine year old boy who wasn't taking part." Jack explained to the stunned guardians, who all nodded at him.

Tooth picked the canister up off the floor and pressed it into Jack's hand. Jack sighed and touched the centre diamond, watching as the memories of young Richard Grayson swam in from of him.

"We have to protect him if Pitch returns" Jack stated a few minutes later. He looked at each of them in turn, daring them to contradict him, watching as they all nodded their agreement.

"That's what we do Jack" Tooth said.
"We're Guardians" Bunny finished.
