OCEAN
Garnet searches for Lapis and Peridot. She doesn't even care that the other gems aren't behind her. It doesn't matter anyways, all that matters is that she reach Peridot before Lapis can crush her gem. She can't allow that vision to come true.
She uses her future vision to pinpoint her directly to Lapis and Peridot.
Like Pearl said, Peridot is being detained by Lapis and like the vision, Lapis has chains around P's body.
"Lapis!" Garnet calls as she makes her way over to the two gems.
"Garnet," Lapis says. "What are you doing here?"
"Release Peridot," Garnet says.
"I can't do that."
"Why not? She's done nothing wrong."
"She has, but you wouldn't know that. She tried to hurt Steven while you were out." Lapis creates a water spike.
"It was an accident. He scared me," Peridot says.
"Shut up!" Grows Lapis.
"Lapis, you don't want to do this. It doesn't end well. If you hurt Peridot, Jasper will destroy you. Steven doesn't need to lose you too," Garnet tries to reason with her.
Lapis thinks it over for a little bit before shaking her head.
"Lapis, I saw the future. You hurt Steven more by doing this. You tear apart his world. Lapis you are part of his world," Garnet says.
"She hurt Steven," Lapis whispers.
"If you do this, we lose everything. You may not trust me, you may not like me, but if you crush Peridot's gem, you set off a whole chain reaction that cannot be stopped nor fixed. Please, neither of us want that. For Steven."
"I am doing this for Steven. She tried to hurt him and I'm going to make sure she'll never be able to hurt him again," Lapis says as she lifts the water spike to be horizontal with Peridot's body.
"Do this and I'll have no choice but to destroy you to keep you away from Steven," Garnet says but doesn't summon her gauntlets. Instead she just clinches her fist. "Steven has no need for people who will kill someone rather than let them redeem themselves. If you do this, you can never be around Steven."
Lapis regards Garnet's words and after a while she lowers the spike and allows it to disappear.
She turns toward Garnet and sighs. "I'm sorry. Tell Steven, I'm sorry."
Garnet nods. "Let Peridot go. Release her to me. She's still a gem."
"She might escape and you might let her," Lapis retorts.
"Then come with me back to the surface. You can keep her detained until then. Afterwards, I'll take her from there," Garnet tries to reason.
Lapis looks at Garnet before she turns to face Peridot.
Garnet moves closer to the restrained gem. When she's face to face with Peridot, she summons her gauntlets.
"You try to escape or if I find out you lied, I cannot guarantee that you will ever be able to regenerate," Garnet lets out softly but loud enough for Lapis to hear too.
Peridot gulps and nods her head. At her motion, Garnet dematerializes her gauntlets and turns to face Lapis.
"Deal?" Garnet questions Lapis and Lapis nods her head.
Together, all three gem move quickly to the surface.
"Garnet," Pearl says softly as she, Amethyst and Jasper watch as the three gems emerge from the ocean.
Once on the beach, Garnet grips up Peridot's arm. Though it looks painful, Garnet has somewhat a loose grip on Peridot's arm as she walks with her toward the house.
"What did we just miss?" Amethyst question as Garnet with a detained Peridot make their way into the house.
Amethyst, Pearl and Jasper all look toward Lapis. Lapis looks back at them before making her way into the house. The other three follow.
Once inside, Garnet has Peridot sitting on the couch and she's standing in front of her.
"What happened?" Garnet questions Peridot.
"He scared me while I was adjusting my cannon. It went off but it missed him," Peridot says.
"How far did it miss?"
The other gems quickly make their way to stand behind Garnet.
"He had to jump slightly to the left to avoid it," Peridot lets out.
At that moment, Steven walks through the door. "What's going on guys?" Steven questions as he sees them all standing around Peridot.
"Steven," Garnet says as she make her way over to him. "What happened today between you and Peridot." At the look on his face she bends down to his level. "It's okay you will not get in trouble." She places a hand on his shoulder.
"It was an accident. I scared her and her cannon went off," he says.
"What else?"
"I had to move a little to avoid it."
"Your bubble didn't activate?"
He shakes his head. "No, it wasn't ... I didn't need it."
Garnet nods her head and stands. She turns toward Peridot and the other gems. "She meant no harm," she says, but mostly toward Lapis.
"She apologized," Steven lets out.
Garnet turns slightly to nod at Steven before she turns and walks past Jasper, temporarily grabbing and squeezing her hand and whispering. "Let's talk," before heading to the temple doors.
"Steven, you hungry?" Pearl asks trying to change the subject. There's so much she's missing but she can figure it out.
"Yes!" Steven and Amethyst both yell. "But can I talk to Peridot, alone?" he asks.
All the gems nod and proceed to follow Garnet into the temple, except for Lapis.
Lapis watches as everyone disappears into the temple doors. She nods at Steven before making her way back outside and into the ocean.
