Rey thought for a moment about meeting Kylo and decided to inform Leia.
"Leia, your son contacted me through our Force bond. He wants to exchange the kids for the holocron. He wants to meet in a cave on Mustafar, alone. Do you think it could be a trap?"
Leia thought for a moment. "Ben has much of the dark side in him, but I don't think it's like him to use obvious tricks to trap you. I do not know for sure of course, we should be cautious, but I think it's OK for you to meet him, mostly alone."
"Mostly alone?" said Rey.
"Perhaps you should bring Poe. He is our best pilot if you need to escape quickly. We'll also have a ship orbiting the planet as a backup."
Poe was nearby. Leia motioned Poe to come join the conversation and filled him in on the details.
"I'm happy to join the mission, but this could be our chance to get Kylo," said Poe. "Why don't we trap him instead?!"
"I know we should jump at the chance to capture him, but I somehow I don't feel we should betray him this time, this way," said Rey, "and there might be First Order backup nearby, just like us."
"Alright so you want to play this safe, huh, I still think if we want to win this war, we have to take bold chances," said Poe.
"Yes, but a higher priority is to listen to the Force," said Leia, "is that what you feel Rey?"
"Yes, I think so."
Leia spoke. "Alright it's a plan then. This is risky but we should try to rescue those kids from being used as a powerful tool of evil for a lifetime.
"May the Force be with you."
Rey gave Leia a hug and looked her in the eye. "May the Force be with you too."
Inside the cave, Kylo Ren was sitting on a rock, waiting for Rey. The kids were sitting in a corner, with stun cuffs on their wrists. There was no natural light to see, the only light was a small lantern-like object which Kylo had brought.
Temiri Blagg, the small boy, spoke up. "Are you one of those Sith people? Luke Skywalker used to chop them up so easy, chop them up and put them in soup!" Temiri and the girl, Haita, looked at each other and giggled.
"Luke Skywalker is dead, he won't be coming to save you," said Kylo Ren.
Haita said "How did you get that scar? Did Luke slash your face?"
"Shut up kids."
Temiri said "Do all Sith have ugly scars? Are all Sith ugly? Snoke was ugly. Are you gonna be ugly like him?" The two giggled again.
"If you do not shut up, I will give you a scar."
"Are you going to train us to be Sith like you? I heard you have to eat the hairs of a Kinor bat and the toes of a Gundark to join the Sith," said Haita.
"EEEEwwwwww!" the kids both said in unison.
"I think he's angry all the time because the Sithy food is gross," said Temiri and they both giggled again.
"Maybe no girl will kiss him!" said Haita.
Kylo stood up in anger and ignited his lightsaber. "If you do not stay quiet, I will put this saber through your mouth!" He stayed angry for a few seconds, then gave up, turned off his saber and sat back down. "Eh, I'll be rid of you soon enough."
"All my masters have been angry all the time, it seems the more master you get, the angrier you get." said Haita.
"Quiet!" Kylo whispered, and he tried to listen intently. There was a sound coming from the cave opening. He walked towards the sound, away from the kids.
The crunching sound of footsteps on the cave floor could be heard approaching. Kylo could barely see a figure in the distance.
"Where are the kids?" demanded the figure in the distance. Then two off-white beams ignited in the distance. It was Rey with her double-bladed lightsaber.
"Did you come alone?" said Kylo Ren.
"Do you see anybody with me?" said Rey.
"I see you have a new lightsaber. How. cute." said Kylo Ren sarcastically.
"Are the kids here?" said Rey again.
Kylo ignited his saber. "Oh they are behind me, annoying as ever. Kids! Step into the light! Do you have the stone?" Rey could see the silhouette of two small humans.
"Why do you want it? What does it do? Are you going to use it to hurt people?" said Rey.
Kylo sneered. "It's my business."
"I have it here, answer my question, what are you going to do with it?" and Rey pointed to the pouch at her side.
"I don't have time for this, maybe I'll just take it," and Kylo took two swings of his saber at Rey. Rey blocked both and they started slowly circling each other.
Rey took a swipe at Kylo with her saber. "Are you happy now Supreme Leader? You are on top of the First Order and probably still miserable."
Kylo took three swipes at Rey, she blocked two with the top half of her saber, and one with the bottom half. "My mood doesn't matter. You could have lead the galaxy with me!" They continued to circle each other.
Rey took two swings at Kylo, paused and Kylo struck back twice. "You could have saved lives instead of taking them! Instead you chose hate again."
The two swung and parried for 15 seconds.
"I have the galaxy in my hand, and you have nothing now," said Kylo.
Two more swings.
"There is no happiness in the dark side" said Rey, "you know that, don't you."
"You have no idea what you missed," said Kylo.
Rey shouted, "I would have taken your hand-Ben's hand!" then her tone dropped. "But not Kylo, not Kylo Ren."
Kylo lowered his saber and stepped back. The anger in his face, illuminated only by two light sabers and a lantern, softened.
"Hand over the holocron and I'll consider releasing them!" said Kylo, regaining his threatening tone.
Behind the kids in the back of the cave, Poe waved his arms at the kids to get their attention. Poe signaled to them to stay quiet, and waved for them to come to him. The kids looked at each other, back at Kylo and Rey, then back at Poe.
"Alright fine, we both put down our weapons first," said Rey.
Both Kylo and Rey slowly lowered their sabers until they reached the ground. They remained lit. Both slowly stepped forward without them. With her left hand, Rey reached across her body and pulled out her pouch with the stone inside. Slowly her hand cautiously moved towards his, until they both touched the holocron at the same time.
As they touched the holocron, they both saw scattered images, visions of the past, and the future. It stunned them for a moment until they were able to understand what they were seeing. They both saw Rey's parents abandoning Rey. They saw the First Order surrender. They saw Leia die, and Kylo Ren dying, and Rey dying. They saw Anakin's goodness, his love of Padme, his betrayal of Mace Windu, and his killing younglings. They saw Darth Vader's intense pain and regret. They saw Anakin's deathbed repentance. They saw Ben and Rey, their faces smiling and close, embracing. They saw the Resistance fall, and all Resistance fighters massacred.
Both Kylo and Rey stepped back and the stone dropped. Kylo kneeled on the ground, trying to recover from what he saw. Rey recovered faster and had her lit saber in her hand.
"Did you see what I saw? My grandfather. Younglings." said Kylo, still on his knees.
"Yes…I did. And…other things…" said Rey.
"You, me, my mother, we all died. But we were together and happy. But we weren't. I…I am confused," said Kylo.
Something buzzed on Rey's belt three times in a row. "I don't know what we saw. I'm as confused as you. I hope I don't regret this, but I'm going to walk away."
Rey retreated back, still facing an unarmed Kylo. "Goodbye, Ben." She then turned and briskly ran out of the cave.
Kylo slowly rose to his feet. He looked at the holocron on the ground for a long while.
Then from behind him he heard a familiar voice again. "Hey kid."
It was Luke Skywalker.
Kylo looked at him but said nothing. Luke spoke first. "You probably want to know what those visions were about."
"In the visions I die, in these clothes. Is this going to happen no matter what?"
"Force visions can show multiple possible outcomes of your future. I do not know which of what you saw will come true, if any of it."
"I saw my grandfather, I saw what he did."
"Yes, like you, he made some terrible choices. But he changed. You still have good in you Ben, don't wait until your deathbed like your grandfather."
"See ya around, kid."
And Luke Skywalker disappeared.
