That is, until he opened his eyes.
The blackness vanished and was replaced by Terezi's face. She was prodding him with her cane, looking curious. "Hey, sleepyhead. You're awake," she said. A mocking smile lit up her face.
He waved her away, sitting up and rubbing his eyes. The smooth walls of my room surrounded Karkat. That and Terezi.
They were alone. She blinked her big yellow eyes at him and cackled. "You were asleep for quite awhile."
He raised his eyebrows. "What did you do?"
"Heheheh, what do you mean?"
"I'm sure you did some shit to my room or something." He touched his face. "Or did you draw on me?"
She put on an innocent expression. "I didn't do anything!"
"Yes you did. I know you, Terezi. I'm not a fucking grub."
Terezi rolled her eyes. "Stop assuming things, grumpypants."
All of a sudden, an uneasy feeling crept up on him. The kind that makes you sick to your stomach, the kind that makes you nervous. The feeling when you know something is horribly, horribly wrong. Karkat looked around the room. No blood splattered the walls, no posters were out of place. Terezi was watching him curiously.
"This...something isn't right," He said quietly.
"Heheh, Karkat, what are you talking about?" She asked, but she was looking nervous too.
"It feels like deja vu or some other mumbo jumbo shit. It's weird. It doesn't feel right."
She drew her eyebrows together. "Karkat...you're dead."
He turned to her, surprised. "What the fuck -" He began, but Terezi had changed. Her eyes were a pale blood red, a teal stain blooming on her shirt, which faded to the outfit of that dumb character she used to Flarp.
"Ah -" He felt a sharp pain in his chest and looked down. He pressed a hand to his shirt and it pulled away bright, cherry red.
When Karkat raised his eyes, darkness was creeping along the walls, changing to them to those of the lab. That's right, the lab. It all came flooding back as if someone had broken down a block in his mind.
A hand touched his. He grabbed it, suddenly feeling like He could float away if he didn't have anything to hold on to. Emptiness filled him up, wrapping around him and surrounding everything.
Everything except Terezi.
She giggled softly, a watery smile appearing on her lips. She kissed him - it felt solid and firm unlike everything else. The walls were gone and surrendered to darkness. It was just Terezi, Karkat, and the floor beneath their bodies.
He kissed her back, grabbing her hands and pulling her forward. She leaned back, breaking the feeling of her lips on his. She kissed his eyelids, his nose, his forehead - the feeling of nothingness sank to the back of Karkat's mind.
Though everything was crumbling, they were, for some reason, calm. She rested her head in his lap, taking one of his hands and putting it on her head. He stroked her hair, running his fingers through it and poking the tips of her sharp horns.
She closed her eyes and gave her life up. The floor began to drop away into darkness. He leaned forward and kissed the top of her head, burying his face in her hair.
Karkat didn't think after that. He let himself melt away. Everything was peacefully quiet again, almost like he was dreaming.
Terezi and Karkat crumbled away, their figures scattering and dissolving into darkness.
