"No. I came to let you go." Barry said as he opened Caitlin's cell. She looked around and smirked as she walked out.
"For a smart guy, that was an awfully dumb move." She said in her cold, hard voice as she faced him.
"Like I said, you're free to go." Barry said calmly, standing in front of her, blocking the path. He stared down at Caitlin looking straight into her ice blue eyes.
"What's the catch?" She asked, looking at him with a slight head tilt. Barry took a deep breath.
"You have to kill me." He said, his voice as hard and cold as Killer Frost's as he spoke.
"What is he doing?" Iris asked, her voice filled with worry.
"I don't know." Cisco said, shifting his weight. "But it's gonna be alright." He finished. It has to be. Barry can't die. He told himself.
"You wanna fight, Flash?" Killer Frost asked, putting emphasis on 'Flash.'
"No. I'm not gonna fight you." Barry told her, shaking his head. "But if you want to leave this room. You're going to have to kill me." He told her.
"Don't think I won't." Killer Frost said.
"Then do it." Killer Frost's eyes flashed white as she looked down at her hand, a large icicle growing in her hand. She held the sharp point up to Barry's chest just in front of his heart and hesitated.
"What are you waiting for? What's the big deal?" Barry asked, stepping closer his voice hardening. "Come on. Live up to your name Killer Frost. I want to see some killing." For a moment Barry saw something in her eyes. Maybe it was Caitlin or maybe it was an illusion, but he'd never know.
"I thought you were smarter than that Flash." In that moment, anything Caitlin about the meta in front of Barry disappeared. Anything nice or Caitlin about Killer Frost disappeared as she shoved the ice through Barry's heart. Everything in S.T.A.R Labs seemed to slow. Everyone in the cortex watched in horror as Barry's body started falling to the ground. Something in Killer Frost's eyes flicked and Caitlin resurfaced for a moment.
"Barry? Oh no what have I done?" She whispered in horror. Her hands covered her mouth as she watched the blood slowly seep through Barry's clothes and onto the floor. The Killer Frost returned as their eyes glowed an icy white-silver.
"I did what I had to." She said and disappeared as she blew cold air around her. When the fog cleared, all the cortex could see was Barry's lifeless body laying on the ground. A sob broke through Iris's lips and she clung to Joe, who was crying silently while hugging Iris. Now one of his kids was dead and he couldn't do a damn thing about it. H.R. just watched, silent for once as his fingers tighten around the drumstick in his hand. Cisco was staring at the screen, hands covering his mouth as his eyes filled with tears. It's gonna be alright. His own word echoed in his mind like a curse.
"Barry…" Cisco whispered, his voice breaking. As soon as the fog cleared, Cisco raced down to where Barry was lying. The speedster was on his back, his face in a permanent mask of surprise. His unseeing eyes stared up at Cisco as the ice in his chest slowly melted. Little streams of blood ran across the floor as Cisco started. After a moment, Cisco reached out and closed Barry's eyes. Then tears started streaming down his face as he rested his forehead on Barry's chest.
"Barry I'm so so sorry." He whispered. "This wasn't how it was supposed to go." He said, his voice breaking as he spoke. "I should've gone with you. I should've done something." Cisco squeezed his eyes shut and tears fell. After a few minutes Joe, Iris, and H.R. came down. Iris knelt next to Cisco.
"Think we should tell Oliver and Felicity?" Cisco asked. Everyone just kinda nodded while staring. Barry had been one of the strongest and most hope filled people they knew, and now he was gone.
