Knockout couldn't stop thinking about Y/n. He kept imagining what would've happened if he had told Y/n that he is in love with her.

He had started to hang out with one of the new femmes in the lab, Wingspirit, to try and get his mind off of Y/n but it made him sadder. He felt like he was replacing Y/n but he just couldn't.

Y/n was everything to him. She was always on his processor and nothing would ever change that.

🔴⚪⚫⚪🔴

Y/n walked into the throne room, getting strange looks from everyone.

Megatron hadn't let it get out to his ranks that Y/n was no longer an ally. He loved his little sister even if he was stone cold. She was his only family. She kept him sane in this insanity of war. He told her everything. How he was feeling, his guilt, how he was in love with his assistant, whenever he was in pain. He told his little sister absolutely everything. The thought that she betrayed him made him feel empty, sparkbroken, and alone.

When he saw her walk into the throne room, his optics widened. She ran over, hugging him tight but he shoved her off. He drew his sword and held it at her neck.

The Decepticons in the room were shocked at their master's reaction.

"M-Megsy?" Y/n was terrified, never having been treated like this from her brother.

"You dare to come back here and show your face to me?!"

"W-what? What do you mean? I-I came home... I-I thought you'd be happy to see me..." Y/n started to tremble.

"You're a traitor! You think I don't know that you joined the Autobots?!" Megatron started to press his sword into her neck cables.

She panicked, realizing that they had spies in the Autobot ranks. She quickly thought up a lie.

"I was captured! Optimus decided to give me a chance as an an Autobot so I took the chance! I have information!" She said quickly and Megatron froze.

"You didn't betray us?" Normally he would've been suspicious but he desperately wanted his sister back.

"No! I would never betray you, Megsy!"

She felt awful about lying but she needed her brother back. She needed to see Knockout again.

"I'm sorry, Y/n," Megatron said lowly before he helped her up off the ground. She hugged him tight and nearly stated to cry.

"I missed you. I wanted to come home every day," Y/n murmured and he hummed, hugging her back. He glared at the anyone who looked at them. He was soft on his sister but the same did not apply for any of the other Decepticons, accept for his assistant and Soundwave.

"I have missed you as well, N/n," Megatron said quietly and she looked up at him.

"I'll brief you on the information I gathered later. I need to see Knockout," Y/n said quickly and Megatron hummed.

"Understood. I'll be waiting," he said and he dat down on his throne as she ran out to go to the lab.

She was super excited to see the mech she was so in love with.

She saw him through the little window in the lab door and her spark dropped.

He was there with another femme who was all over him. He was smiling and laughing.

"I'm so glad that were partners," the femme said and Y/n watched as the femme kissed him.

She started to trembled as she turned around quickly and her spark was beating so fast.

"H-he..." Y/n started to cry and she dashed towards her room.

Snowflame, Megatron's assistant, saw the femme crying and quickly went after her.

"Y/n, I heard that you were back. What's wrong?" She asked Y/n as she

"Knockout doesn't love me anymore! I-I should've come home sooner! He has a bondmate now and it's not me!" Y/n sobbed out and Snow frowned. She hugged the sobbing femme and comforted her for a while, glaring at any vehicons that gave them strange looks since they were in the hall.

"Snowflame, what are you- Y/n?" Megatron had gone looking for Snow when she didn't return with his reports.

He walked over to his sister's side and she looked at the ground, feeling so broken inside.

"What's wrong, N/n?" He asked, concerned about her since she almost never cried. She may not have been as stern and cold as him since the start of the war but she still was strong. He knew something had to be very wrong for her to be crying like this.

"Knockout is with another femme... I-I thought he loved me... he kissed me before I left and we never got to talk about it but now he doesn't love me... I wanted to be with him..."

🔴⚪⚫⚪🔴

Starscream walked into the lab witha groan.

"What's your issue today, Screamer?" Knockout asked unenthusiasticly having just lost a friend since he told Windspirit that he didn't want her after she kissed him.

"Y/n is back and as annoying as ever. I thought the scraplet was a traitor but it turns out she was acting as a spy. I still don't like her," Starscream complained but Knockout perked up.

"Y/n is back?!" He asked quickly and Starscream nodded.

"Yes. I just said that, you idiot," Starscream scoffed and Knockout was out the door so fast.

He looked for her and when he saw her in Megatron's arms, standing in the hall, he quickly ran over.

"Y/n! You're back!" Knockout smiled bright but quickly frowned when he saw that she was crying. "Y/n?"

"Go back to your lab, Knockout. You are not wanted here," Megatron ordered gruffly.

"But-"

"Go!" Megatron glared.

"But, my liege, she's my best friend!" Knockout stood his ground, suddenly feeling brace, only because he wanted to see Y/n.

"Why you-"

"Stop..." Y/n said weakly, cutting off her brother.

"Please just let me talk to her," Knockout begged and Megatron looked at Y/n.

"It's okay. I'll meet you in your room later, Megs to give you my report," Y/n said to her brother softy.

Megatron huffed but left with Snow, taking the reports from his assistant as they walked back to the throne room.

Y/n couldn't look at Knockout so she just looked at the floor, tears trickling down her cheeks. Knockout  hugged her tight and rubbed her back.

"What's wrong, N/n? Why are you crying?" He asked with worry.

"B-because... you moved on... I saw you with your femme in the lab... I came home and I thought we were gonna get to be together but I was too late... I really love you, Knockout... I know I'm too late but I really love you..."

"But you were with Wheeljack," Knockout said in shock, thinking she had been with the Autobot wrecker after seeing them together in the recording.

"No... he's just my friend... I wanted to be with you... I wanted to bond one day... but now you have someone else," she sobbed out and Knockout quickly shook his helm.

"No, I don't! Wind kissed me earlier and I told her that I don't have feelings for her! I still love you! I will always love you!" Knockout said quickly, holding her closer to him.

"R-really?" She looked up at him only for him to kiss her deeply.

She kissed back immediately and wrapped her arms around his neck. She pulled away after a few minutes and smiled.

"I love you so much, doll. Nothing, and I mean nothing, will ever change that," Knockout said and Y/n hummed before running her servo over his chassis.

"I love you too. I'm back now and you won't have to worry about not being able to reach those hard spots when you're buffing," she said jokingly and he chuckled.

"I actually made a new friend who has helped me out with that. His name is Breakdown. He's on a mission right now but I'm sure the two of you would be great friends," Knockout said and Y/n laughed.

"I'm sure. Now come on, I wanna be back in the lab. I don't think I'm going on missions for a while."

She walked with him back to his lab, guilty that she was lying and she knew she would have to come clean soon but for now, she was happy.
