(So, for those that was impatient or patient and like this story here's another chapter I finally had the time after my brother got the whole family sick.)

Mabel stared in shock as her brother killed Undyne. But most of all that black energy around him made her terrified of her own brother. Isn't that crazy she is terrified of him?

She stood there trembling as Dip…no Mason continued walking and looking like he was talking to someone, but no audio was coming through their end.

"So, he really did it. To Papyrus and Undyne." She said silently she felt an arm on her shoulder and looked up and while he still had his cheery smile he was searing with rage. His eye was glowing blue.

"Sorry kiddo but your brother made his choice and even if it takes forever." Sans looked down at her. "I have to kill him."

"Wait he can change I know he can. Let me try to SAVE him!" Mabel begged Sans. The Skeleton sat his hand on Mabel's head and calmed down for a moment. "My job as the judge it requires me to judge anyone that steps into the judgement hall and I can't act before that under any circumstances." He clenched his fists as his eye glowed with brighter.

"You really think you can SAVE him?" Sans asked. Mabel was unsure about this but still nodded. Sans chuckled for a moment he was still angry but if he can be saved then perhaps…." Hey kiddo why don't you tell me about your past."

"What do you want to know?" She asked confused Alphys was wondering the same thing.

"When your brother started this, what caused him to become what he is now. I'm sure you know."

"Well." She hesitated a bit and spoke a bit more.

~Dipper and Chara~

"So I been wondering how is it you hate humans so much and have this much blood lust?"

"Well." He answered

"It was after our parents died. We were only 5 but our first home wasn't that great." Dipper and Mabel answered at the same time

~7 years ago~

"You'll be staying here while we look into any living relative you 2 may have." The social worker told the twins.

"Back then Dipper wasn't anything like he is now. Actually, he scared of everything." Mabel said to Sans and Alphys

They walked to the door with the social worker and he knocked on the door. The door opened to show a well-dressed man while slightly on the heavy side he was fit and he cleaned himself up nicely. They looked behind the door and saw that the living room and Kitchen we clean.

"Doesn't sound so bad." Chara said

'Wait for it." Mason replied

"Frank thank you again for taking Mason and Mabel in. Remember this will be temporary until we can find available family to take them in." The social worker told him as they talked a bit more while a Butterfly flew by Mabel's face and she chased after it causing Mason to run after her as well.

"Come on Butterfly come to me." She giggled as she jumped up to try catching it but she couldn't reach it.

"Mabel what are you doing?" Mason said running after her now on the side of the house. He tripped and fell on the ground next to the basement window.

"What was in it?" Alphys asked

"Dipper never told me only that he tripped there." Mabel said

"Lot of them." Mason said to Chara.

"Lot of what?" She was curious

"Bodies." He told her

Dipper looked for a minute seeing the whole room every inch of it covered in blood and various machines as well as lifeless bodies lying across the floor. He was scared and wanted to know where this guy even came from. He tucked himself into a ball and cried right there he wanted to run hell even die.

"Oh there you are Mason. Where's your sister?" The social worker asked. He then saw Mason lying on the ground crying and picks him brushing off. "Are you ok what happened?"

"And you didn't tell him, right?" Chara responded

"Wouldn't be a story if I did. Also, I was too scared after seeing the bodies that I couldn't talk." He told her

"And the guy didn't find it weird that you were facing the window?"

"I held my head and curled into a ball it would look like I hurt myself and not get scared to anyone else. And before you ask no there was no way into the basement by normal means that's why he passed the background check."

"Because they missed the basement?"

"No, they didn't know it existed."

"I got you Mr. Butterfly!" A 5-year-old Mabel yelled as she caught the bug she was chasing and as she opened her hands to look at it the insect flew out of her hands and into the distance.

"And I got you Mabel." The social worker said scooping Mabel up and walking her back to the front of the house where Frank was still waiting. "Sorry about that Frank you know how kids are."

"All is well I'm sure they didn't get into anything they weren't supposed to." Frank said as the social worker sat the twins on the ground and ushered them inside. Mabel ran in screaming like a maniac while Mason hid behind the Social worker's legs not wanting to be near that man.

"Look Mason I know this is a new change for you and your sister, but this is what your parents would want for the both of you to grow up in a nice home. Can you do this for them?" He asked Dipper in a sweet tone.

"He didn't know shit." Dipper swore

"It was so amazing in there the couch was the best I ever sat on." Mabel said

Mason looked at Mabel who was having the time of her life and back to the car. If he ran away he couldn't protect Mabel like he promised so reluctantly he walked in and Mabel grabbed him by the wrist and pulled him up onto the couch she was jumping on. He joined her while he was still feeling unease at what he saw but kept a smile on for sake.

The moment the social worker drove off Frank came back in and slammed the door shut and look at the twins for a moment before grinning. "Hey, have you kids eaten yet today?"

"Chicken!" Mabel yelled

"Alright and I'm guessing Mason had the same thing?" Frank asked they nodded. "Not much of a talker, are you?"

"N-no sir." He squeaked

"Well guess I should tell you the rules while you both are under my roof. No desert, no leaving your rooms before noon and be in your room at 5:30 every night. Since it's already 2 you both can look around if you want then go up to your separate rooms."

"So, what was with the separate rooms?" Alphys asked

"I don't feel comfortable saying." Mabel asked Dipper told her long after but only cause she wouldn't stop asking.

"That doesn't sound like a fair time to go to sleep or leave your room." Chara commented

"It wasn't. The other guys treated us much worse but at least they didn't do anything like that." Dipper said

The twins looked around the house while Frank said he had to step outside for a phone call.

"Hey Mabel want to see who can find more coins?" Mason asked her

"Challenge accepted." And she ran right for the couch and shoved her hand inside it digging around.

Mason crept up to behind the door and put his ear up to it to listen to the conversation.

"You heard me twins." Frank said over the phone.

"No way that ones mine you can have the other for $15000." He told the person on the other line.

"Watch who your calling insane. After this deal I need to get out of here. If these kids suddenly go missing while I'm the caretaker then I need to leave immediately."

"Well that could work. I'll bring the kids today and we can decide the payment after?"

"Great. See you then." Dipper ran from the door and into the kitchen. After hearing the whole call he knew this man was bade news. Frank was still no where in sight must have gone to a different room.

He walked back to Mabel who dug up 3 pennies, a button, and a corn chip. She ate the corn chip.

"Gross Mabel." Mason chuckled as she started to cough from the bad taste. "That's what you get." She pushed him to the ground and climbed on top of him as they rolled around.

Frank saw the twins playing in the living room took some pictures and grabbed a can before turning on the TV.

Mason and Mabel stopped after hearing the TV was turned on and sat on the floor watching it. Not long from then it was time to go to their room. Mabel tried bagging while Mason stayed quiet but Frank sat their thinking then grinned.

"Actually, if you both do something, I'll give you a 30 minute extension." He spoke

She grabbed her brother shaking him yelling. "Did you hear that Mason 30 more minutes that's, that's like a whole year." Mabel shouted then both of them stood up in front of the man.

"Get in my car I need to run some errands. If you behave then I'll let you stay up another half an hour." Frank said Mabel was about to scream yes but Dipper saw they haven't even unpacked yet and covered her mouth.

"Um Mr. Frank. We haven't unpacked can we do that first?" Mason asked wanting to keep Mabel away from this man.

"Alright take your thing up to your rooms and I'll wait in the car. He grabbed his keys and headed out the door while Mason and Mabel dragged their belongings upstairs. Getting to their new rooms they saw were down the hall from on another. Mabel opened her door and it looked like a normal room with a bed, dresser, and window. Not much else.

Mason's room however had nothing in it. He frowned a bit and threw his stuff on the ground and dug in his pocket and pulled out an object. It was a small pocketknife that belonged to their father he grabbed it before they were taken away. And put it back in his pocket.

"Wait you took a pocketknife from your dead dad?" Chara asked

"Yes, if I remember correctly it was 6 inches." Mason told her

"So you gonna tell me what was with the dead bodies?" Chara asked

"Fine, those bodies were all of children. I found out he was a child molester." Mason told her

"What the fuck?" She responded

"You asked I answered." He said snapping a monster's neck

Mason walked out his room and saw Mabel waiting for him. "Well bro bro di you finish?"

"Yeah, but I'm tired. I think I'm going to sleep right now." Mason told his sister as she looked at him for a moment before walking downstairs to the car. Mason goes to his window and opens it and grabs a pipe to slide down.

"Wait how do you know about the parts you weren't there for?" Alphys asked

"Oh, Dipper told me." She told the scientist

"Well I'm assuming he was smart for his age back then." Sans commented having calmed down.

"Yeah he was." Mabel answered sadly

He got to the ground as peaked around thr corner to see Mabel hasn't gotten in yet so he walks to the car slowly and when he gets to it he uses his small size to his advantage and crawls under the car and grabs on. At this time Mabel finally came out the door and got in.

"Where's your brother?" Frank asked

"He was tired, so he went to sleep." She told their foster father. The man sighed and stated the car both people in it completely unaware that Dipper was under it and Frank drove off.

After half an hour and Mason nearly losing his grip several times Franks finally stopped the car in front of a house and looked towards Mabel. "Alright we're here. Care to join me?" Frank asked

"Yup." Mabel said as she hopped out of the car with Frank and walked towards the house.

"Hey Phil, I'm here with one of them." Frank said through the door while knocking. Those words did not escape Mason's ears as he narrowed his eyes and dropped to the ground and crawled out the ground. And ran up to a window where he saw several individuals in the living room none of which is facing the window but facing his sister Mabel.

"So, where's the boy?" One of them asked

"Apparently he decided to go to sleep. I'll bring him tomorrow for now let's enjoy what I did bring." Frank answered

Mason let go of the window ledge and ran around to the back and checked the back door to see if he could sneak through and to his luck it was so he knocked on the door and hid nearby.

"Wait did your brother really tell you all of that?" Sans asked

"Yeah he was actually pretty smart he was never caught either." Mabel answered

"Wait you don't mean?" Alphys asked Mabel nodded

"So, hold up what the hell went through your head when you were 5? Cause that's not a normal mind set." Chara asked

"Protect Mabel." Mason answered

"I can't tell if you pure evil or just a really overprotective brother." She told him cause how Mason was she can guess what's about to happen. "Was it hard to out smart them?"

"Just listen."

"I got it guys don't do anything without me." One of them said and not even a minute later the door opened, and the man took several steps outside and looked around. "Another one. Probably a neighbor's brat." He said and before he could register what was happening Mason jumped out the bush with his knife and plunged it in his chest killing him on the spot and ran inside to hide.

'That's one.' Mason thought leaving no trail or proof that it was him and hid inside a cabinet. "Hey what's taking Jeff so long?" One of them asked in an agitated tone.

"Yo the doors still open!" Mason hears 2 sets of footsteps go to the back door. "What the fuck! Jeff's dead!" One of them called out.

"What do you mean dead?" Frank called out.

"I mean someone stabbed him in the chest. Probably the same son of a bitch that knocked on the door."

"Well who the fuck else would it be!? Marry Poppins!?" Frank yelled he grabbed Mabel ready to head out the door. "Fuck this. Before this deal goes to shit, I'm out of here."

"Frank you better not be bailing."

"And what if I am?" Frank shot back

"The guy that just killed Jeff could be out there waiting for you. Ty your going with Frank and check around the house I'm I'll check inside with Sam."

"Alright and what about the girl Kevin?" Frank asked

"Ignore her." He responded. Mason managed to crack the cabinet slightly and look to see Frank and another guy leaving with Mabel probably to put her in the car. "Sam I'll check up stairs our assailant you look down here." Kevin said before pulling out a gun and walking up the stairs.

Sam took a look around the bottom floor of the house looking where anyone could have hidden. Well any adult no one was expecting a child to be the out for them. After a minute Sam gave up. "Shit the guy's clearly not down here. I'm getting something to eat. He walks over to the cabinets and opening the one Mason is in. His eyes went wide as Mason used his knife to slit his throat as he jumped out of the cabinet.

"A kid." Sam gurgled chocking on his own blood. Mason saw Sam writing with his blood but he stopped him and put the knife in his head killing him.

Mason knew the other guy, Kevin, would be down soon so he hid on the ceiling fan in a room not seen from anywhere near the stair case being small he didn't weight a lot so he didn't do anything but make it anything but unsteady.

"Yo Sam find anything?" Kevin called out. After a minute Kevin asked again. "Sam is the guy down there?" Mason heard stomping coming down the stairs and he looked around. "Sam when I call your fucking name you answer!" He called out then walked the opposite direction from where Mason was who jump off the ceiling fan and quietly followed the guy.

"What the hell Sam to?" Kevin said seeing his acquaintance dead on the floor with the letter "K" written in blood. "Stab wounds so this guy only has a knife and the cabinet is open so the person is small. No, not just small it's a child. But why would a random child want to pick a fight with us? Unless there's a connection between one of the previous children or the girl." He grinned. "So that's it that bullshit that you went to sleep was so you can get here without anyone knowing." Mason hid quickly jumping up to the wall and stabbing his knife into it. To hang there but the noise didn't go unnoticed by Kevin and he ran to where Mason was only to find only the knife but no Mason.

"Come on kid I know your in here." He kept his guard up as he looked around the room waiting for Mason to pop out so he can shoot the brat. Mason watched him from where he was hidden waiting for Kevin to be position.

The ceiling fan wasn't in the best condition and could fall at anytime if enough force was put into it. "You little shit come out!" Mason stomped as hard as he could causing the ceiling fan to fall on Kevin it knocked him out. Mason grabbed his knife and took Kevin's gun before stabbing him repeatedly in the face.

"Hold up you went from timid to professional assassin in less then a day. How?" Chara asked

"That's what I did? I just made it up as I went along." Mason told her

"You took the guy's gun. You killed 3 of them with a single pocketknife catching them off guard and dropped a ceiling fan on the other." Chara realized something. "How high did you jump to get to the ceiling fan?" She asked

"8 maybe 9 feet." He answered

"You had your powers since you were 5. Great now everything can go back to making sense." Chara said dramatically

"I just learned about it a few days ago how is it possible that I had it that long?"

"It's your SOUL even if you don't know how to control it or even use it, it will still linger and yours back then increased your physical attributes otherwise everything you did would have been bullshit." She informed him.

"And now?"

"It does everything and that. Now continue the story."

He went back over before the other 2 came back and got rid of the 'K" Sam wrote in blood and closed the cabinet. After he looked out the window and saw Frank and Ty talking.

"I'll talk to Kevin and Sam about finding this guy remember to bring the boy tomorrow and we'll talk a price."

"Sounds like a plan. Sucks for Jeff though. He won't get to enjoy himself with he twins." Frank said grabbing his car keys and getting his car and driving off.

Mason didn't get a word of that but he watched as Ty turned around and came towards the front door and Frank just drove off so he pulled out the gun waiting for Ty to open the door Once he did Mason pulled the trigger. The bullet went into Ty's chest but the recoil broke Mason's right hand.

Mason saw the body fall to the floor as he put the gun back in his pocket and ran in the direction of Frank's car. He knew he wouldn't beat them back, but he just needed to get to his room before they check on him.

He hopped a couple fences and through various ally ways and he was still nowhere near where he needed to be. But from a distance he saw Franks car. He didn't remember much other than its black. Also, he could clearly see Mabel not sitting still. He pulled out the gun again. And tried to aim it at the tire but because of his broken hand that was proving to be difficult.

He fired a shot, but he missed, and it went into the passenger's window and shot the rearview mirror.

"Who the fuck just tried to shoot me!" Frank yelled out his window. After that shot Mason's left hand was now broken and his right hand was slightly worse now. He hissed in pain but put the gun back and ran down the street while Frank was in a rage and somehow before them he got back to the house and ran around back and climbed up to his window where he got in and closed it before pretending to have been asleep.

"Mabel go to your room." He heard as they came in. He heard his twin walk up the stairs. "I was supposed to get more time." He heard her sulk to her room and close the door.

Mason heard Frank's footsteps going to the opposite direction towards a different room. Mason tried to get up but his the pain in his hands were getting to much. He tried to muster the strength to get up and this caused his hands to get even worse as his bones pierced his skin and his blood was spraying everywhere.

"And he still went through with that even without his hands?" Sans asked

"Yeah he was Determined to kill him. What he did was written down as an accident cause they would never expect a child to kill on purpose."

Mason stood in his room and the gun fell out of his pants and he walked out of his room. He heard the shower running so he walked downstairs to the kitchen and grabbed a knife with his teeth and walked back up the stairs.

"Bro bro?" Mabel asked seeing her brother walking up the stairs. Mason's eyes went wide Frank didn't hear her and was taking a while. Dropping the knife out of his mouth he looked at Mabel.

"Mabel what's wrong?" Mason asked

"Your hands did you cut them with the knife?" Mabel asked seeing his hands.

"I didn't know then but now I do. He messed up his hands and was going to stab Frank using the knife with his mouth."

"Yeah, I was going to ask Mr. Frank if he can help me cook something as thanks for taking us in."

"I lied to her cause I didn't want her to be hurt."

"Should I get some band aids?" Mabel asked. "Will that help?"

"I want to save him from whatever is making him like this. Maybe he can reset everything then." Mabel told the 2 monsters

"Yeah it will a lot. But can I ask Mr. Frank something?" Mason asked Mabel nodded and turned the doorknob slightly but before walking away a hand grabbed her.

Mason grabbed the knife with his broken hands causing him to hiss in pain and more blood poured out and ran through the door. There was steam everywhere.

"Dipper!" Mabel yelled

"Come on I held it in all day and that damn brother of yours ruined my fun with that bullshit." Frank yelled as he tried to slide his hand up Mabel's shirt but Mason plunged the knife into his wrist. Frank screaming in pain a 5-year-old just stabbed him with his own knife.

He threw Mabel to the side and kicked Mason in the stomach which forced him to flying into the door clutching it. Frank walked over to him and started stomping on the boy. "You little shit if you didn't try to shoot me earlier I wouldn't have caught you." Reeling his leg back once more he kicked Mason sending him to the ceiling. The impact broke several bones and he started to cough up blood.

Before Frank stomped on him again, he managed to grab the knife again and brought it up to Frank's foot as he went to stomp on him.

"You fucking shit!" Frank fell over. He couldn't believe he was losing to a child in a fight. "You're not even worth selling!" He screamed now having a hole in his foot and Mason walking towards him. Instead of running to stab him somewhere vital Mason reared his arm back and threw the knife at him which went right between the eyes.

~End of Flashback~

"I blacked out right there." Mason said, "Actually Mabel and I were unconscious, so I have no idea how I woke up in the hospital which I stayed in for a while. "The gun broke my hands and fractured my arms, Frank shattered my ribs one of the bones nearly stabbed my lung, and apparently my heart stopped for a few minutes when I got there."

"By all logic you should be dead." Chara said as Mason stopped walking and asked her. "So, this is the next stop, right?"

"Yeah, MTT Resort. We're almost done."

~Mabel, Sans, and Alphys~

"You seemed to know about him killing others yet you reacted like you never seen it before." Sans pointed out

"He told me about a few but this is the first I ever seen him do it."

"It looks like its almost time." Sans said getting up. "I wonder what I should get from Grilby's." He chuckled as he was walking out the door. "Hey kiddo you coming?"

"Yeah. By Alphys I promise everything will be fine. I'll make sure to get you with Undyne as soon as possible." She said before running out the door after Sans with a equally big grin on his face.

"So, kid you sure you want to do this?"

"Yeah. I'll save him and everyone. But I know he won't fight me so I need to hide me face." Mabel inquired

"Here." Sans said tossing a blue coat on her head. She took it off and looked at it. "Don't give me that look it's mine from when I was a baby bone. Haven't worn it in years so it's all yours."

Putting on the coat and pulling the hood over her head she looked to Sans and gave him a hug. "Thank you and I promise when this is over we should all go to Grillby's together. "You, me, Papyrus, Dipper, Undyne, Alphys, Goat Mom, even Flowey."

"You mean that psychotic flower?" Sans asked concerned

"Yeah. I know I can help him to just like I will Dipper." Mabel said with Determination

(Yeah this was an idea all along I just wanted to know how I'd put it in. Since I wanted a chapter where they talk rather then fight another boss I decided right here would be perfect. Every other option I had got Mabel killed and I don't want that.)
