The doomed timeline

Chapter 20

A few hours went by, and Karkat layed there with Dave. It wasn't like they could go anywhere. Dave had already explained his plan. All they had to do was wait for Dave to get back.

Soon they heard footsteps coming up the stairs. Dave quickly shut his eyes, moving into the same position as he was when he woke, and tried to slow down his breathing to make it look like he was still dead. A few seconds later there was the sound of keys, and the door swung open. Dave walked in, holding the knife loosely, walking over to Karkat and Dave.
"Hello Karkat. Hope you weren't too bored while I was gone. I managed to get everyone here," he said, grinning.
Karkat didn't answer him, keeping his back turned.
"Oh, come on Karkat. Don't give me the silent treatment." Dave walked closer to Karkat.
"I'm not talking to you, you killed him..." Karkat mumbled, hoping their plan would work.
"Oh, did I now?" Dave laughed. "Well that's great!" He grabbed Karkat, pulling him away from Dave. Karkat tried to twist away from him, but Dave kept his hold and dragged him further away, then let go heading back over to Dave. "So if I killed him, then I guess he wouldn't react if... oh, I don't know... I stab a knife into his chest?" Dave twirled the knife in his fingers as he spoke, smiling.
Karkats eyes widened. They had not planned for this. He struggled against the rope. "Don't!" Karkat thought desperately for a way out of this. "Haven't you hurt him enough?! He's already dead so what's the point in stabbing him?!"
Dave tilted his head and smiled." Exactly. Hes dead, isn't he? Then it shouldn't matter if I stab him or not, right?"
Karkat didn't answer. He was trying to think of what to do. Dave held the knife up and was about to bring it down. Karkat did the only thing he could think of.
"Dave, move!" He new their plan had failed, and he did not want to risk Dave actually dying.
Dave opened his eyes and quickly rolled out of the way just as the knife came down. He'd narrowly avoided it. He cursed.
"Did you really think I'd fall for that?" Dave laughed, stepping towards them. "You cant fool me. You can't surprise me. So why don't you just give up"
Dave walked over to Karkat, who started struggling to stay away from him. "Don't touch me!"
Dave just smirked and bent down, cutting the rope from his legs, then doing the same to Dave. "Get up, and don't think about trying to do anything. I will not hesitate to kill him." Dave said as he pressed the knife to Dave's throat. Karkat stood up, wobbling a bit from his leg. Dave got up as well.
"Where are you taking us?" Karkat asked, leaning against the wall.
Dave smiled. "Where going to go see the others."
