Luke sat on the edge of his bed, watching as the light from the fire in the hearth danced over Rey in the darkness as she slept in the opposite corner.

It was useless for him to try and sleep, especially when his mind was so troubled.

Kylo Ren had made it clear today that he was trying to reach out to Rey, but why?

Luke knew that was the question in Rey's mind, though she had remained virtually silent for the rest of day following the incident during their morning meditation.

Seeing the memories that Ben showed her and speaking to him as an equal had clearly moved and compromised her emotions about him—Luke could see that.

The big question for her was what was his endgame?

And while he admired his daughter's open heart, Luke wasn't so much concerned about Ben's intentions in connecting with Rey like he did, but how he was doing it.

Luke knew Rey had a strong and independent will and Luke was confident that, after what he had seen during their few training sessions together, that his daughter could hold her own in a physical fight.

His main concern was that Ben would do damage to Rey by continuing to draw on their mental connection through the force.

Somehow, he sensed that Ben didn't wish to harm Rey by drawing her energy to him…at least not yet. But, if it continued, it could be disastrous.

It could also lead the First Order right to him, Rey and the island.

It was for this reason that, long after Rey had gone to sleep, Luke had stayed up, meditating and sorting his thoughts, focusing on the form of his sleeping daughter to draw forth any thoughts and memories—memories of Ben and Rey's childhoods, Ben's time at the Jedi Academy—anything that might point to their connection through the force.

Luke knew that the force could be strong between family members—he and his sister, Leia, had had a strong bond from the beginning. And it was one that had only grown stronger over time. But, they were twins where Ben and Rey were cousins…

Twins.

Suddenly, Luke took in a short gasp and stood from his bed. He had found the memory.

He shifted his eyes immediately toward Rey, making sure his actions hadn't awoken her and, when confident that they hadn't, wrapped his robe around himself, threw up the hood and walked out the cavern door.

Fifteen years earlier...

Luke stood with a resigned face, his arms folded as he stood at the edge of the Jedi Academy courtyard and peace gardens.

They weren't very 'peaceful' at the moment.

Ben was clearly upset, letting his rage consume him as he pacing back and forth through the hedges and the benches.

Luke watched as his nephew splashed his arm angrily through the water fountain, splashing water in every direction as he screamed in frustration and threw the Kyber crystal in his hand onto the ground and stomped it with his foot.

The crystal, resilient to all forces, didn't break and that only seemed to frustrate Ben more as he continued to try and destroy it with his boot.

"Oh…my…" came a bewildered voice behind Luke and he immediately looked over his shoulder to see his wife, Mayla, standing behind him, holding Rey, four years-old, in her arms.

"Yeah…" Luke sighed as he continued to watch Ben as he angrily paced around the crystal.

"Sweetheart," Mayla said, turning to Rey, "Cousin Ben needs our help right now. Why don't you go inside and wait for me, alright?"

Rey nodded and Mayla lowered her gently to the ground.

Luke smiled and brushed his hand gently over the crown of her head as she ran past him.

"What set him off this time?" Mayla asked, her voice worried as she came up behind her husband and brought her chin to rest thoughtfully on Luke's shoulder

"He's angry, frustrated…He was supposed to be in seclusion, building his lightsaber, but his mind is unfocused and the Kyber crystal isn't responding."

"How long did he last?" Mayla prompted

"Less than a day," Luke sighed again, disappointment in his voice

"That's not a good sign," Mayla replied, her eyes still focused on Ben

"No…" Luke said in a resigned voice, turning to her, "It isn't."

"What are you going to do?" Mayla asked, meeting his gaze

"I'm not sure—" Luke started, then turned quickly when he heard a crash and saw that Ben had sent one of the stone benches flying with the use of the force and it had landed in the grass on the other side of the fountain, smashing into numerous pieces.

Then another went flying and broke against the garden wall.

Suddenly, Mayla saw a figure across the courtyard, walking toward Ben

It was Rey.

"Luke…" she gasped, grabbing Luke's arm and pointing toward their daughter who was walking right toward Ben…and, it now seemed, imminent danger.

Luke quickly broke free of her grasp and started across the courtyard, but stopped in horror as Rey came right up behind Ben, where he now held up another bench, ready to throw it.

"Ben!" Luke cried, trying to get his attention, but as Ben turned, the little girl now standing behind him did that.

Ben stopped, seemingly startled by Rey standing there, staring at him with a stunned expression as she looked up to the bench he still held over his head.

Then her gaze came down and they locked eyes for a few moments before Rey's face softened and she walked toward him.

Without a word, she leaned down and picked up the crystal at his feet, then moved forward and wrapped her arms around his legs.

"Don't worry, Ba Ba. I help you."

Still standing there with the bench over his head, Ben gasped and a sudden peace seemed to come over him again.

He looked down to where Rey still hugged his legs and gave a small smirk, then exhaling deeply, tossed the bench aside.

Luke let out a relieved breath, turning in relief toward Mayla, before he turned back and watched Ben slowly lean down and hold out his hands to Rey.

Rey smiled and handed the crystal up to him.

Ben took it and placed it into his pocket without breaking eye contact with her, then held out his hands again and she took them.

Rey cried with glee as Ben swung her up into his arms.

"Then let's go, Monkey," he said, "This time, you can be my good luck charm."

Because Rey was so young, she couldn't stay with Ben during the entirety of his meditation in the temple at the academy, but Luke brought her every day he was in seclusion.

Their routine was the same.

Near dawn, he would awaken and dress her. They would have breakfast and then Luke would lead her to the temple and leave her at the door and she would go in alone. He would watch as she made her way quietly into the sanctuary and sat down next to Ben, where she would stay until mid-afternoon when Luke would come to collect her again.

Luke was mesmerized by her.

Rey had just passed her fourth birthday and already she had a quiet dignity about her that was beyond her years.

In another two years, she and those in her young-ling class, would construct their own light sabers—a skill not limited to a certain age, but something Luke felt should be mastered early so that the force could inform all that his pupils would become from the earliest age.

Lately, he had worried, though, that the children might be too young for something that took such concentration and skill, but seeing Rey sit there quietly at Ben's side as he meditated over his crystal the past few days, gave Luke every confidence that she was ready.

Luke smiled as he thought of R2 sitting with him when he built his own light saber years before, staving off his physical loneliness so that his mind could focus.

Rey was doing that for Ben. There seemed to be a connection—a bond between them from Rey's early years that couldn't quite be explained.

Ben seemed to watch over her and Rey, in her own way, over him.

On the fifth day, after teaching a class of fifth year students, Luke went to the temple to collect Rey.

When he came to the door, he heard talking inside.

Ben sat across from Rey, holding out his newly constructed light saber for her to see as he tossed the hood back on his robes.

"What color!?" Rey shrieked with glee, much like the four year old she really was, "What color?!"

Ben smirked, then maneuvering the handle, brought the light saber to life and it gave off a beautiful green glow that instantly lit the darkness of the temple.

"Oh…I like it. It's like Daddy's." Rey observed

"I suppose it is…" Ben said, looking at the blade in careful thought, then retracted the blade and brought his gaze to Rey.

"Are you disappointed, Ba?" Rey asked

"No…" Ben replied with soft smile as he shook his head, "Thank you for sitting with me, Monkey. You really were my good luck charm."

"You're welcome," Rey replied, then smiled back, "You're my brother."

"Well, not exactly…" Ben chuckled, "But close enough. You were lucky, though. You once had a brother. That's more than I ever had."

Luke closed his eyes in sorrow at those words, remembering the day Rey was born.

She was to be a twin—the healer had been clear— there was a boy and a girl.

Luke could sense that both were strong with the force and he and his wife were thrilled at the prospect of not one, but two babies.

But, there were complications with the birth and the first born of the twins, a boy they would later christen Anakin after Luke's father, was stillborn before Rey made her appearance minutes later.

"I suppose…" Rey said, looking down in thought as she played with the arms on the doll Luke had made her by hand in the form of a Rebellion fighter pilot, "I still see him in my dreams sometimes. He said he gave me his power."

"What?" Ben asked, narrowing his eyes in curiosity, "What do you mean?"

"When we were in Mummy's tummy—when he…" Rey paused for a moment then shrugged

Ben just sat there, stunned, unsure what to say until Rey looked up to him.

"It's our power, now," she said in a proud voice, "I'm keeping it safe for him."

# # # # # # #

Luke took in a reverent breath as he removed the weak stone in the floor of the temple sanctuary and from beneath it, pulled out a wooden box.

He looked at it with hard eyes then finally willed himself to slide back the lid.

Inside, was Ben's original lightsaber, the one he had built over a decade ago, in Rey's company.

The one he had abandoned in favor of his grandfather's lightsaber-blue-the color of wisdom and power in the Jedi order.

It was a color that he felt less ashamed of. Green was a color he probably felt he had only obtained because Rey had been there with him, influencing him.

Decades before the lightsaber had been used to kill young-lings in an attempt by the Sith to wipe out the Jedi, then thirteen years ago, history repeated itself.

When Luke had chased Kylo Ren down, seeking vengeance after the massacre of his students and his wife, he had won his father's lightsaber back in battle, forcing Kylo to build his own again.

Luke eyed the saber in front of him now.

This was it.

Luke was confident that this was what Ben was using to make the connection between himself and Rey stronger.

Ben may not know the location of his original light saber, but as long as it existed, the connection between him and Rey could never be broken.

But, more importantly, Luke had come to realize something else in meditating on his memories, that the key to the prophecy was tied to the words he heard Rey speak all those years ago, when she mentioned her deceased brother for the first time in the temple with Ben.

Luke stared at the light saber, a chill running over him as he repeated the words to himself.

"A savior lives when a savior dies…and does not fear this life's goodbye."
