Reincarnated as Underswap Sans and how about Error get kidnapped instead?

haha hello and welcome back to the cringe! Shut up.
Warning: Cringe, wrong grammar drama or etc... probably logic? Maybe.

"Hey, I'm sorry- OW!" Swap smack Ink's ass with his blue left boot and his brother and Error had to watch while Ink's getting punished. After minutes of punishing Ink like a child (LOL), Swap let him get out of his grasp. "What did I even do wrong?" Ink whined and Swap just let out of sigh. 

"What did you do wrong? Simple, you tried to kill my ruru." Swap said as he lifted his boot and ready to smack Ink. Ink sweat drop and letting out of nervous chuckle. "H-Hey, I'm sorry alright? And who's even ruru?" "tHaT wOuLd bE mE." Ink tensed up as he turned left to see Error and Carrot. Ink eye sockets were wide and shocking to see Error. "E-Error?!" "h-HeYa sQuId." "Where have you been! I have been looking everywhere for y- OW!" Swap cut him off by smacking his skull and Carrot let out of sigh and better not to mess with his brother. As for Error, raise his bone brow and confused. The question is, why would he'd be looking for Error?

"sQuId, wHy? i sToPpEd DeStroYing coPiEs of aUs, d-DiDn't i? sO wHy aRe sTiLl loOkiNg fOr mE?" Error questioned and Ink just sigh. "Well, because I wanted to apologize for not knowing about the balance and I wanted to make a truce with you." Ink answered and Error surprised that his idiotic enemy had finally realized about the balance. Like seriously? How come? What's the change?

Swap fake cough to get their attention and they turned on Swap. "So now you realized of how stupid you were back there and finally stop making bunch of shit copies?" Swap said seriously and his brother started smoking and Swap just took the cigarette and ate it. His brother's face was like, 'WTF bro'. Ink just ignore of what he just saw lol, "Well yeah, I realized that and I stop making copies of aus- wait... I AM NOT STUPID!" Ink pouted and Swap couldn't help but laugh. Carrot and Error was like, 'this is normal'.

A few minutes later, they both made a truce and Ink writes his scarf down just incase if he forgets about the balance and the truce. Swap felt pleased at that and Carrot, well he's proud of his brother. Ink was about to leave but he stopped and had an idea. He walked over to Swap and ask him to join the star sans and Swap flinched of what he heard from Ink. He was about to denied his offer but he accept it. Ink is now a happy fried calamari! (Ink: I'm not! Author: Shush!)

Error suddenly felt like someone is watching them, but who? He faced to the fourth wall but he can't see it though. He was not sure what it was but he'd be better not to let his guard down.

Meanwhile with Fate and Destiny....

"I'm so proud of you, my two children! The multiverse is now stable!" Fate said happily and Destiny felt pleased. "But still... I feel bad for leaving my second child to suffer-" "Sister, it's over now. You didn't mean it and besides, you did good and I'm sure Error will forgive you." Fate sigh and hoping her sister was right. "You are right, and thank you for staying on my side, Destiny." "Of course! That's what are sisters for!" both of them laughed and continuing watching them.

"ACHOO!" Swap sneezed and he felt like someone is literally watching him. That would be you, readers. You readers are the ones who are watching. Creepy- 

"Bro, you alright?" Carrot ask concern. "Yes brother, I'm fine. I just feel like someone is watching us." "Oh? Is that so?" "Mhm... And do not worry! I will make sure no one will hurt you and Ruru! Even If I have to beat death itself!" Carrot chuckled and Error let a hummed and not gonna ask of this.

Meanwhile from another au...

"ACHOO!" he sneezed and felt like someone is mentioning him. He does not know why but he never felt more scared before. "Sans, are you all right?" "Oh- um yeah, I'm fine, Toriel." He just left to reap some souls and trying to ignore this feeling.
