Timeline and plot outline
Rey had trained with Luke for a while on the island then they left to help the Rebellion. She hasn't yet passed her trials so she's still his Padawan, not a Jedi Knight. They're in a battle, she sees that Luke's ship is in danger, she does something to make their attackers chase her, she instinctively reaches through the Force and is pulled out of the present to a safe place and time where her only Force sensitive relative lived. The relative in question being her grandfather Obi-Wan Kenobi, the place being Tatooine and the time, a few weeks before Obi-Wan and Luke leave the planet (so before A New Hope)
Chapter 1
After the initial shock and apprehension, her grandfather turned out to be a good host. Unfortunately, he was worse than useless. Due to the potential of ruining the course of history, they were forced to be quiet most of the time. And what the absolute worst, he was so technically inept Rey was beginning to doubt they were related.
She couldn't get too mad at him. It wasn't his fault he was from a time when the Jedi order had access to technology and didn't actually need to know how stuff worked. The problem was that she needed to fix her craft and try to find that nexus again to turn back to her own time.
She wasn't even angry she was back in the desert. Obi-Wan's place was cool, and he made a decent cup of tea. But how was the man able to live without as much as a screwdriver in the whole place? They had to go to Tosche Station to get a toolkit and some basic parts for repairs.
"Blasted!" she exclaimed and threw the soldiering iron towards the ship only to stop it using the Force when it was a hairsbreadth from smashing into it.
"Your master must be remarkable," Obi-Wan said.
She looked over her shoulder to where he stayed watching her work so unmoving he seemed at one with the shadow of the house. The observation sounded ironic and she opened her mouth to defend Luke. Obi-Wan he interrupted her.
"No, don't tell me details!" he said. "I meant that your proficiency with the Force is extraordinary considering how powerful you are. It's difficult for someone so powerful to exert precise control, as you just showed when you reigned in your temper not smashing the tool. And that's after you tried to fix that wire fifty-eight times before the outburst."
She looked at him, trying to decide if he meant it or was a veiled insult.
"He is," she said.
Thinking about her master was the last thing she needed. Was he all right? Will he be all right? She didn't know in which tense she should be thinking of him.
She sat down on the scorching sand. She closed her eyes and murmured.
"Jedi understand their limitations. We recognize, and take responsibility for our failures and develop a level of modesty about them."
Obi-Wan came to sit next to her.
"You need help to fix the ship, don't you?"
She nodded, defeated.
"I have to get back, Master Kenobi."
The old man chuckled.
"That's a title I haven't heard in a long time," he said. "I know someone who can help you."
She brightened a little at the news.
"He's a boy who lives on a farm nearby. He's very good at fixing things."
Rey's heart lurched. Could he possibly mean… She knew Luke Skywalker's life story. She knew every bit there was to know. Her master had even told her about the awkward time he had kissed his sister. Obi-Wan hadn't warned Luke that Leia was his sister fearing it might affect the future, and now… he would allow a time traveler to talk to… Luke Skywalker.
"You have to be very careful, Rey. He is very important and he doesn't know it. Promise me you will just get him to help you with the ship."
"But he's going to figure out this ship is not a model available now," she said, certain that her grandfather was so bad with technology he wouldn't notice, but her master definitely would.
She saw Obi-Wan hesitate before speaking. As if he was uncomfortable about what he was going to say.
"I'm sure you can distract him," he said, and coughed. "He has a good heart," he added sounding so bitter that Rey thought maybe he didn't need her to tell him the future because he already knew it somehow.
A couple of hours later, she was surveying Tosche Station, waiting for Luke to show up. Her master had taught her the art of camouflage and she practiced it best on desert planets, like her own Jakku. He could always spot her when they were training in jungle environments, like Dagobah, but desert camouflage was her forte.
The two suns of Tatooine were burning, but Rey felt her palms sweat. Her heart was pounding so hard she worried she might faint. She sensed Luke's imprint in the Force when he was miles away. She shook off the sand and went into the small settlement. Not knowing when he was going to show up, she had used Jedi techniques to be unseen. Now that he was approaching, she made herself visible.
The girl who ran the store recognized her from her previous visit with Obi-Wan. Rey pretended to want to buy a power converter and she was talking technicalities when Luke walked in the room. She felt his energy in the room, so recognizable as his, and yet so different. She listened to his footsteps coming closer. She wanted desperately to look at him.
Jedi are aware of the future impacts of action and inaction and of the influence of the past, but live in and focus on the Now. We let ourselves flow like water through the events around us. We embrace the ever changing and fluid world, adapting and changing as it does.
"That model is pretty good," he said. "Hi, Camie! Where's the Fixer?"
"In the back, working on a droid. Miss, you're in luck. Luke is the best when it comes to fixing things. You can ask him anything," she said and left them alone.
Rey was still frozen. She could see him out of the corner of her eye. She had to turn to see him or she was going to seem peculiar.
"What do you need it fo…?"
His jaw dropped when she turned to face him. She hoped she was doing a better job of covering up the effect he had on her. He was the cutest boy she had ever seen. His blond hair was like a perfect halo. His blue eyes, so bright. There was no trace of pain, fear or guilt.
"I-I have to repair a ship," she said.
Rey's voice had never sounded so squeaky in her life. She was grateful no one who had to look up to her as a Jedi got to hear her.
"Oh, awesome! What model?"
He seemed to have recovered quickly. Maybe not, she thought, seeing that his eyes were half black now. She wondered if her own pupils had reacted the same way. How humiliating! Well, it looked like some distracting was required.
"My name is Rey," she said.
"Luke," he answered.
That had totally backfired, she realized when she saw Luke's hand, thrust earnestly forward. It took all her training to be able to shake it. She was touching his right hand. His real right hand. His flesh and blood hand. Warm, dry and soft. Letting it go was more difficult than she cared to admit. But she had to let go. For his sake.
"Is she right? Are you the best at fixing things?"
He blushed. The boy blushed and his long lashes fluttered. He was embarrassed! He was adorable.
"Yeah, I guess."
She smiled, more at ease now.
"You think you can help me?"
"Sure! What do you need?"
"First, I need to buy that power converter. Second, I need help fixing a skyhopper. And third… I need a ride back. My grandfather dropped me here and I guess he forgot to come and get me."
On their way to his landspeeder, Rey told him where they were going.
"Ben Kenobi?! Old Ben is your grandfather? Wow!"
He said "Ben" with such nonchalance. Rey felt like he'd hit her with a blaster. How could he not know? How could he not feel what the future had in store for him? In her present, whenever master Luke's thoughts went anywhere near his nephew, Rey could feel the Force like a swarm of locusts instead of the pure beautiful energy she usually felt.
The strategy she had agreed with Obi-Wan was to minimize any possible consequences by asking him questions so that he wouldn't get the chance to ask her. She asked him about things she already knew from history, or from Luke himself.
"We race T-16s in Beggar's Canyon. I thread the Stone Needle, so I always win. I can take you there some time. If you want…"
If she wanted to see the greatest pilot in the Galaxy in the place where he first honed his flying skills? He might as well ask her if she wanted to breathe in and out.
"Sure, I'd love that," she said, knowing that she would never get to see that.
They arrived at Obi-Wan's place and Rey could tell that as soon as Luke saw the ship he knew it wasn't any of the models he had ever heard about. Her master had spent his childhood and teenage dreaming of being a pilot. He knew every available model. She had to distract him before he started thinking about it.
"See, this is where I got stuck," she said, and took his hand to lead him to the part where she had failed fifty-eight times by Obi-Wan's counting.
"Oh, that's fiddly," Luke said and he inserted long, curious fingers in the wiring. "Ah, I see what you tried to do. No wonder it didn't work. It's a two men job. Two… two.. people job. A man and a… a…."
He was floundering. Could he possibly be any sweeter?
"I get it. It's ok. Well, we're two men now," she said, and reached into the wires.
Their faces were so very close. Her fingers were brushing his. He did that eyelash fluttering thing and Rey melted inside. She wanted to hug him and hold him for as long as it took for her heart to calm down. Instead she stepped away and went into the house to bring the toolkit.
They worked for a few hours. She couldn't help testing him a few times, and every time he unconsciously reached for the Force. That was to be expected, and it was easier to deal with than the looks. She didn't have to catch him looking to know that he was following her every move.
"I have to go home now," he told her, looking down.
"Thank you, Luke," she said, the name catching in her throat. "You've been wonderful."
"I can come tomorrow, too," he said quickly, darting a glance at her. "If you want me, of course."
If he hadn't been for the blushing and the sound of his voice, Rey could have sworn he was flirting with her. She wanted him to come again. The words sounded dirty in her mind. She had kept such thoughts out of her mind when it came to her remarkable master, she was not going to mess everything up by entertaining them about an innocent boy, no matter how delicious he looked.
"There's still a long way until this thing can fly again," she said. "I'd really appreciate the help."
"You have me. It. You have it. My help."
Rey watched him get into his X-34. Followed the landspeeder with her gaze until it disappeared from sight. She couldn't wait to see him again.
"Tomorrow," she whispered.
