Jasper slammed their fist into the wall next to Lapis' cell, leaving a visible dent and waking the meditating Lapis from their repose.
"What did you say to Peridot!?"
"What?" Lapis jumped to their feet, stumbling and slipping back to the ground "n-nothing"
Collecting themselves they took a deep breath, crossing their arms defiantly "They were trying to 'interrogate' me"
Jasper growled softly, eyes narrowing "You are my prisoner. You should understand what that means."
Lapis snorted "I've been-"
"I OWN YOU!" Jasper bellowed making Lapis tremble slightly "IF YOU EVER WANT TO BE FREE AGAIN YOU WILL REMEMBER THAT!" They breathed heavily, staring at Lapis with burning rage.
"You can't threaten me" Lapis stood, their voice catching slightly.
"I don't like you Lapis" Jasper spoke softly, turning their back to the cell "You may not remember me. But the names and faces of every gem we lost on Earth are seared into my memory. I can never forget the things we did there… And when I heard someone had returned…" Jasper leant against the wall, their fingers digging into the metal "I was so… Happy? Finally someone I could talk to! Someone who would understand what we had to do!" They paused for a few seconds, quieting down to barely a whisper "Do you know how many gems came back from Earth?"
"No. I mean, I didn't see much after… after it happened" Lapis looked down at their hands
"Not many. And most of them didn't hang around. They left for distant worlds, to travel, to fight… or to die. I'm the only veteran left on Homeworld" Jasper fell silent.
"I understand" Lapis moved closer to the door of the cell, reaching out towards Jasper "I-"
"SHUT UP!" Jasper screamed, turning to face Lapis, tears in their eyes "It wasn't any of them, it was you! A coward and a traitor! You said you 'didn't understand' our Home, you who should understand better than anyone what we have sacrificed to build this world, what we lost in order to stay strong!"
Lapis stared at them in shock, they didn't realise the brutish gem was even capable of such emotion.
Jaspers eyes narrowed and their voice dropped to a venomous hiss "and that's why, if you betray us again, I will crush you. If you are anything less than helpful during this mission I. WILL. CRUSH! YOU! And if you do anything to Peridot" Jasper breathed heavily bringing their face as close to the cell as possible, making Lapis step back "I will make you suffer."
Jasper hung their head for a few seconds before growling huskily "You didn't deserve to survive. A lot of good gems were broken on Earth. You should have stayed there." Jasper pushed themselves back upright and stormed away as Lapis tried to find their voice, sliding down the back wall to hug their knees against their chest.
