Hey guys you are gonna kill me but i am going to skip ahead in the story to the final fight in the castle with Flowey

Rosa had been through all sorts that could only be described as hell she had to fight for her life against Undyne, do varies battles against Mettaton and even had to avoid becoming a dancing spiders next meal. After all of this she finally met the king of all the monsters and even after he forced her to fight him she refused to kill him. He was on his hands and knees and she spared him only for the little flower to kill him and take the human souls transforming into a large creature that Rosa had to fight. Luckily for her she had just survived the ordeal by the human souls coming to her rescue as Flowey was about to kill her. After which Rosa left the Underground she felt saddened that she would leave the monsters down their. Toriel, Papyrus, Alphys, Sans. As she looked at the sunset in front of her she slumped to her knees and began to cry as the thoght of leaving them forever set in her mind. But at that moment Flowey had popped up and told her that she had a special power he used to have. She could go back to before she had fought Asgore back when she had just delivered Undynes letter heck even after Alphys came out with the lab incident. Rosa didn't need to think twice before she did what Flowey told her and used her 'reset powers' and when she opened her eyes she was stood outside the barrier. As she went to enter she thought to herself. 'Flowey had better not be lying to me'.

Rosa walked in and saw Asgore just like before he pulled out his spear and prepared to make the first move when suddenly a heat filled the room. Just as the heat arrived Asgore was sent back by a fireball. Rosa gasped as she saw Toriel enter the room glaring at Asgore holding her hands out towards him. Rosa didn't care that she was just about to fight Asgore anymore she ran towards Toriel happy tears filled her eyes as she wrapped her arms around Toriel hugging her. Toriel chuckled softly and hugged her back.

"Do not worry my child it is I your friend Toriel" Toriel told Rosa that she believed that the fight between the two should be held off because no one should die for the freedom of the other, which Rosa was more than happy to agree to. As the fight had ended all of Rosa's friends had started to fill the room thinking they were preventing the fight. The last person to enter was Sans who just smiled saying.

"'sup" Rosa smiled and ran over and hugged him saying.

"So I guess I still haven't gained LV or EXP, huh?" Sans smiled hugging her back avoiding the gaze of his brother who was smiling slyly.

"ha guess so kiddo" Sans then stood next to his brother and Toriel who spoke.

"my child it would seem as if you must stay with us for a while. But looking at all these great friends you have made I do not think this will be such a bad thing" Rosa started getting happy tears in her eyes but suddenly a sharp pain struck her and the next thing she knew she was held up by a thorny vine as was all of her friends. Flowey popped up laughing.

"You idiot, you have learned nothing. In this world it's kill or be killed" Rosa managed to speak although the thorns were stabbing into her.

"Why are you still doing this?" Flowey laughed.

"You see if you finish the 'game' then you won't want to play me with me anymore. Tell you what if you do beat me then I'll give you your happy ending, I'll break down the barrier, I'll give back the souls and I'll let your friends go" His expression then went dark. "But that won't happen. You." He began to tightening the vine stabbing the throns deeper in. "I'll keep you here no matter what even if that means killing you 100,000,000 times" Suddenly Rosa was surrounded by the sharp pellets and the pellets repeatedly stabbed into Rosa's body. Rosa was now bloodied and in a great deal of pain but as the final round of pellets went towards her a large wall of fire destroyed the attack.

"Do not be afraid my child. For even if things look bleak we shall always to be here to protect you" After all of Rosa's friends protected her each time she felt her health returning. After this she had managed to escape from the vine and glared at Flowey as all of the monsters that she had met entered the room willing to protect her from Flowey. Suddenly Flowey began to laugh.

"You idiots all your souls are mine" A bright light blinded Rosa and made her cover her eyes with her sleeve. When the light dimmed a small goat child was stood there he was wearing a green and yellow striped jumper with a pair of black pants. He smiled at Rosa and said. "Chara, are you there? It's me your best friend Asreil Dreemur" In another bright light this Asreil was now as tall as Asgore with Toriel's dress on. He pulled out a large sword and swung at Rosa nearly hitting her again and again before he pulled out a large gun that continuously fired stars until it fired a large rainbow coloured ray. Rosa had dodged millions of attacks but could feel herself getting weaker and weaker. Soon after Asreil had showed another more powerful form she could now feel the weakness setting in and as a darkness was surrounding her making her start slumping. But then she sensed a strong pull from Asreil's soul as if the other souls were still resonating within him, standing up Rosa forced the souls out one by one. She had promised Toriel and Asgore that she would be with them forever and that she thought of them as parents, she then told Alphys that she wanted to watch Anime's with her and that she believed in her, she then lightly punched Undyne and asked Papyrus about cooking spaghetti. Then lastly she found Sans' soul. She had told him some skeleton puns expecting him to laugh but what he said made tears form in her eyes.

"Just give up I did" Rosa considered talking about his brothers but instead she walked up to him and hugged him whilst crying.

"please come back to me Sans I feel like you know me better than anyone. I already lost my father please don't let me lose you" Rosa suddenly felt a hand on her back she looked up and saw Sans looking at her smiling.

"Don't worry you wont" He hugged her back tightly and when she let go she found herself standing in front of Asreil and even though all of her friends were saved she could still feel a soul that wanted to be saved. I walk forward as Asreil starts going backwards.

"No! I don't need anyone! Leave me alone!" He suddenly fires a large beam of light but Rosa carried on until he sighed and stopped and started whimpering. "I'm so afraid Chara, I'm so alone Chara, I'm, I'm.." In a bright light Asreil had gone back to his child form he was crying and wiping his eyes. "I always was a cry baby wasn't I Chara" Rosa gave him a confused look. "I know your not Chara, Chara left ages ago" Rosa saw that he seemed more upset so she moved forward.

"My name is Rosa" He looked up and smiled.

"Rosa? That's a nice name. Look I know that you might not want to forgive me I've done so many bad things" Rosa smiled and walked up to him hugging him. "I don't want to let go" She hugged him and then let go as he broke down the barrier and as he walked away to leave Rosa's eyes began to tear up. "Oh and Rosa take care of mum and dad for me" He then walked away and in a moment she felt a dizzy spell and collapsed. Rosa awoke and saw all of her friends surrounding her and all together they walked to the surface where Toriel had asked what she would be doing and Rosa had asked if she could stay with Toriel. Toriel allowed her and said how if she wanted she would be her parent. When Rosa went home with Toriel she was taken up to her new room where she saw that she had a large bed and the room was painted white as Toriel said that she could paint it herself when she had settled in. Rosa couldn't be more happy she had a mother and a father, Toriel and Asgore, she was the ambassador to the monsters and she had a large group of friends. But something felt missing and after thinking about it for the entire day the thought hit Rosa. Flowey. She had always thought he was just an evil weed but after meeting Asreil she understood that he couldn't help feeling that way. So late at night when Toriel and Asgore had thought that Rosa was fast asleep she grabbed her coat and backpack and placed a plant pot, a trowel and a large piece of rope in the bag. She climbed out of the window and made her way to the entrance to the Underground. She tied the rope to a uprooted tree and made her way down when she saw Flowey looking upset she walked towards him when he said.

"Rosa? What are you doing here?" She pulled out the plant pot.

"I want you to come with me" Flowey scoffed.

"why cause you think you can make me feel something again? That won't happen" Rosa sighed.

"No because you are the only one who understands about the resets and everything I can't tell the others" Flowey seemed shocked.

"Well what about Smileytrashbag? You can talk to him about this stuff"

"No I can't there are somethings I can tell him but not everything. Please Flowey" Flowey sighed.

"Fine but you can't tell anyone that I'm really Asreil. I don't want them to see me like this" Rosa smiled and agreed before placing him in the plant pot and setting off home and placed him on the side drawer. When she fell asleep she didn't know this but Sans had teleported into her room to check on her when he saw Flowey.

"What are you doing here weed?"

"Rosa brought me here trashbag" He glared at Flowey but still went to Rosa making sure she was sleeping peacefully before turning to leave. "Hey Sans" This made Sans turn around surprised he wasn't called his nickname. "You better watch over Rosa and keep her safe"
