Across the timelines [an Undertale Fanfic] (revised)

Goodbye Chara

"Chara? Are you sure about this?" Flowey asked as he watched Chara gather up some of the flowers. He remembered everything from that day, how the flowers made him very sick. Chara couldn't get out of bed and was just in a very horrible state, and he didn't know if he could see him like that again. "Isn't there another way to fix everything?"

Chara shook his head no. "Not that I know of. Gaster only told me about this, and even if there was another way, I don't think I can do it by myself." With that, he took a deep breath before stuffing his mouth with the flowers, poisoning himself. He couldn't help but feel weak as he dropped the remaining flowers he had in his hand on the ground, coughing. "Be-besides, I deserve this. I... deserve to die."

"Chara?!" Flowey called out, not liking what he saw. He knew the plan, knew what he had to do, but he couldn't help it. It was just like he was watching this for the first time in his life all over again. He watched Chara die once, and as if falling into old habits once again, couldn't help but get as close to him as he possibly could to help him. He just didn't want to watch his best friend die thinking that everything bad that happened to him was his fault. "I told you before that this wasn't a good idea! Why are you doing this? This wasn't your fault!"

"Yes, it was!" Chara shouted back as he fell to his knees. He felt sick to his stomach now, and became very dizzy. He remembered how last time it took Asriel to help him get back home. This time, he wasn't going to wait all night to die. Once he was sure that Frisk was alive and well, he'll end it for himself. After all, what use is he alive. "It's my fault. It's all my fault that you're stuck like that. It's my fault more than half the underground is dead. It's my fault that I ruined this peaceful timeline, and I'm going to do whatever I need to to fix it again."

Flowey shook his head no as he leaned closer to Chara. He watched his friend as a pained look came across his face, but couldn't help but notice how calm he was being. Chara was dying, and he wouldn't make a sound, or complain about it. He just looked determined to see this out to the end. Last time he saw this look, Chara was gone for a long time.

"Flowey, no, Asriel. Everything was my fault. I was the one who started this mess all those years ago. I was the one who let my hatred control me. I brought Player here, and I let him control me." Chara gave him a weak smile as he knocked over Flowey's pot unintentionally, letting the soil spill out among the flowers to release him. "Brother, I can still hear him. He's in my head, and he's screaming at me. I can't let him out again. I just can't. I'm not strong enough to stop him myself."

"I can't watch you like this. I don't want to watch you die again!" Flowey said as he started tearing up. He couldn't help it. He's seen enough death to last him a lifetime. "I love you, Chara. I don't like watching you die, knowing I can't do anything to help you."

Chuckling a bit, Chara said, "I know this is probably the worst thing I could ask you to do, but thank you. I'm not going to die right away, so how about checking on Frisk? See if he's alright for me?" He couldn't help but gently touch one of Flowey's petals before saying, "take care of him for me, okay?"

"Okay," and with that, Flowey was gone. He moved into the ground and traveled all around, hoping to find the other boy. It wouldn't take long for him to find Frisk, not since he was no longer bound by the flower pot. Flowey could search for him anywhere now and was determined to find him as soon as possible.

Chara looked up at the sky above him as he felt around for the familiar weapon in the flowers. "Looks like it's game over for us, huh, Player? We had a good run together, but the fun has to end sometime..." Tears began to fall down his face as Chara couldn't help himself. He was going to die, and even though he wanted to stay with the others, was determined to never return. He didn't want to interfere with this timeline anymore than he already had. It's time for him to return to his own home...
