Today was good day for Lincoln as he and his friends spent three hours at Dairyland Amoosement Park. He was in a good mood as he managed to beat all of his friends at the arcade games that Dairyland recently installed. He was now driving home after dropping off his friends at their houses. Once Lincoln got home he notice it was quiet too quiet but Lincoln didn't think anything about it. Lincoln enjoyed the peace and quiet as that was rare occurrence to happen in the Loud house. Lincoln walk to the kitchen for a snack but was block off by Luna.

Luna: Sorry bro I can't let you in as Lori in there cooling off.

Lincoln (confused): Why is she in there cooling off  and can I at least grab a snack as I'm hungry

Luna: She and Leni had a huge fight and according to the sister fight protocol any two siblings must be separated until they cool off.

Lincoln: Sister fight protocol? When did this thing come to be.

Luna: Me and the others except for Lily as she was napping, came up with this during a sister meeting.

Lincoln: And why wasn't I inform about this and better yet do mom and dad know about this?

Luna: Well you know about it now and too answer your other question mom and Lynn Sr do about it.

Lincoln: You can call Lynn Sr dad.

Luna: I know but me and others don't have a close father-daughter relationship and we view you as our father figure.

Lincoln: I know but can you at least grab me a snack?

Luna: Sorry bro no can do.

Lincoln (slight annoy as his good mood is being ruined): Fine

Lisa walks into the kitchen holding a bagel

Lisa: You could have this bagel.

The bagel Lisa was holding had mold on it, had a green tint to it and smelled horrible.

Lincoln (disgusted): Ew, no thanks, I believe Lana wouldn't eat that.

Lincoln: Lisa quick question did you come up with this sister fight protocol?

Lisa: Yes actually, it took me two months to come up with this.

Lincoln: I'm going let not telling me about sister fight protocol sooner slide for now but if this causes me anymore problems then I'm going to get involve.

Lisa: Now dear older brother unit there no need to get involved as the sister fight protocol is flawless and is currently working fine.

Lincoln walks upstairs to head to the bathroom but is block by Lana

Lana: Sorry Lincoln I can't let you in Leni is in there cooling off.

Lincoln (getting tick off): Let me guess sister fight protocol ?

Lana: Let me guess Luna told you?

Lincoln: Yep, also mind telling me about this huge fight that Lori and Leni had to cause this?

Lana: Lori and Leni bought the same dress and neither of them want to return their dress. So we enacted the sister fight protocol.

Lincoln with a tick mark: So this entire thing was cause by Lori and Leni buying the same dress and being too stubborn to return their dress. That got to be the most stupidest thing I ever heard of. Me and Clyde wore the same shirt for picture day and we didn't care.

Lana: It's a sister thing, you wouldn't understand.

 After Lana said that Leni came out of the bathroom but she still look like she was angry. Lincoln B-Line it to the bathroom before any of his other sisters or his parents could get in.  

A few hours later Lincoln was on his laptop listening to Life Is A Highway by Rascal Flatts. He was currently mouthing the lyrics trying to forget the events of what today but unfortunately fate had other plans. Lincoln was enjoying himself but that came to a halt when Luna, Luan and Lori barge in his room.

Luna: Lincoln we need your room so Lori can cool off.

Lincoln was mad that his relaxation was interrupted as he was just getting into the music.

Luan: So make like a banana and split haha get it but seriously Linc we need your room.

Lincoln (annoyed): Fine, I'll go watch Dragon Ball Super on the TV as tonight is a new episode.

Once Lincoln got downstairs he turn on TV and switch the channel to the the anime channel. He was getting comfortable but Lynn and Lucy took the TV remote and turn off the TV much to Lincoln dismay.

Lincoln blood was now boiling as his anger was starting to take over but he manage to keep it under control.

Lincoln in a stern tone: Girls you know that when my Saturday anime is on. I don't like to be disturbed.

Lynn: We know and we're sorry but your violent anime show isn't going help Lori and Leni  cool off. 

Lincoln: How is my amine show going to effect Lori and Leni cooling off?

Lucy: The reason is that people are fighting and it might cause Lori and Leni to fight each other.

Lincoln: If they did fight I would end it as it is my job as your big brother too end any fights my siblings have.

Lucy: We know but when the sister fight protocol is in effect. We separate the fighting siblings.

Lincoln sighed knowing Lynn and Lucy weren't going to take no for answer.

Lincoln: Fine, I'll go to my room, listen to music or video chat with Ronnie Anne but before I go I'm going to record my show for tomorrow.

Lincoln heads upstairs and enters his room but he notices his sheets are off his bed. 

Lincoln (yells): WHO TOOK MY SHEETS OFF MY BED!

Lana enters Lincoln room and said

Lana: I did we're using them as a divider for Lori and Leni.

Lana then throws some towels on Lincoln bed.

Lana: Here you go and before you ask yes their clean.

Before Lincoln could say anything Lana was out of his room.

Lincoln: Alright I'm getting involved in this BS 

Lincoln then walks out his room and stomps on the floor hard enough that some of his sister were wondering why Lincoln was stomping the floor but when they realize that he was heading to Lori and Leni room they panicked. They began to tell him it was sister fight protocol and it was a sister thing he wouldn't understand but it fell on deaf ears. 

Lincoln barges in Lori and Leni room and takes his sheets back.

Lori and Leni: Hey what was that for?

Lincoln (angry): I'm taking my bed sheets back as I never said it was ok for any of you to take my bed sheets 

The loud sisters were telling him that the sister fight protocol was fine and they would resolve this on their own.

Lincoln (yells) QUIET!

The loud sisters stop talking

Lincoln was giving them a glare that would here no more back talk. 

Lincoln (angry): Alright I'm getting myself involve, Lori your spending the night with Luna, as she is moving into your room and Leni your spending the night with Luan as your moving into Luna and Luan room.

After Lincoln was done Luna move into Lori and Leni room while Leni move into Luna and Luan room. 

Narrator: The next morning

Lincoln was slowly getting himself out of his bed as he was not a morning person. He was getting himself dress but was interrupted when he heard Luna and Luan arguing. Lincoln sighs knowing that he cause this to happen, he finish getting dress and sees Luna and Luan being guarded by Lynn and Lucy who were wearing greenish-yellowish vest

Luan: I'm telling you Luna, Leni had the dress first.

Luna: No way sis Lori had the dress first.

Lincoln tries to walk past them but Luan grabs his arm and she is not happy.

Luan (angry) Lincoln we told you not to involve with the sister fight protocol.

Lincoln: I'm sorry I got involve, you girls know how I act when my anger takes over.

Luan (sighs): Just don't get involved again.

Lincoln: Ok, I won't get involve again.

Luan: Thank you

The day when poorly for Lincoln as Luan and Luna were now fighting as well Lori and Leni. Lincoln was kick out of his room three time. The first time was for Lori, the second time was for Luna and third time was for Lola as she and Lana were fighting. Lincoln felt his anger beginning to rise but was trying his best to keep it under control.

Lincoln decides to call Clyde to see if he can go over to his house and play video games and watch TV.

Clyde: Hey Lincoln what up?

Lincoln: Poorly Clyde.

Clyde: Why that?

Lincoln tells Clyde the events from yesterday and today and once he finish telling Clyde. He was beyond shock that his sisters did something like this.

Clyde (shock): Let me get this straight this all started when Lori and Leni bought the same dress and neither them could have come up with some suggestion or alternatives and they block you from the kitchen,bathroom and prevented you from watching the latest episode of Dragon Ball Super which I have to admit was awesome.

Lincoln: Correct and don't spoil anything.

Clyde: Can I at least tell you one thing?

Lincoln: Fine.

Clyde: Let just say that Jiren get overwhelm by a certain someone.

Lincoln: Clyde could I come over to house for a little bit to play video games or watch TV?

Clyde: Sure thing Lincoln.

Lincoln: Thank Clyde.

(A/N: In this AU Clyde doesn't have a crush on Lori. I personally think that the writers need to have Clyde get over his crush on Lori as this reminds me of Dipper crush on Wendy from Gravity Falls)

Narrator: A two hours later. 

Lincoln was leaving Clyde after watching TV and playing video games. Lincoln was hoping for this sister fight protocol nonsense to be over with but when Lincoln open the front door he notice that Lynn,Lucy and Lisa were now fighting.

Lincoln: Great now all of my sisters are fighting but I'm not going too get involved.

As the day when on Lincoln anger was starting to rise again as he was denied access to the bathroom, kitchen and kick out of his room one time.

It was now night time and Lincoln decided to tell his parents about how the sister fight protocol basically screws him over as he been denied access to the kitchen, bathroom and how he been kick out of his room multiple times. After explaining this to his parents they were mad that their daughters were blocking off the bathroom and kitchen and kicking Lincoln out of his room. At first they were going to bring an end to the sister fight protocol  and punish the girls for their behavior but Lincoln manage to convince them that he would punish them as they view Lincoln as their father and wouldn't take the punishment seriously if it was given by Lynn Sr. 

Lincoln walks upstairs and takes a deep breath and said

Lincoln(yells): GIRLS MY ROOM NOW!

Every Loud sister knew that if Lincoln called for all of the Loud sisters into his room and yelled. They knew they did something wrong but couldn't figure out why he mad as he didn't get involved all day. With all of his sisters in his room they notice Lincoln had a look that showed anger,sadness and betrayal.

Lincoln in a stern tone: Fine a place to sit as we're going to have a not so pleasant conversation.

The Loud sisters found a place sit and were wondering on what Lincoln had too say.

Lincoln(mad): Now that your all comfortable we're going to have a not so pleasant conversation about the sister fight protocol.

All of the Loud sisters eyes when wide after hearing that as they realize on why Lincoln was mad. He was mad at them which emotionally hurt the Loud sisters as they view him as their father figure and has been very supportive of all them throughout their lives.

Lincoln: I spoke with mom and dad and told them about how I was denied access to the bathroom, kitchen and was kicked out of my room seven times. So we agreed that the sister fight protocol is here by abolish.

The Loud sisters eyes widen after hearing that the sister fight protocol was abolish. They were about to counter argue that the protocol work fine but they couldn't say anything as they saw Lincoln had a glare that would hear no counter arguments.

Lincoln in a upset tone: Lori and Leni I am highly disappointed in both of you. The fact that this all started that neither of you two could come up with alternative solution with having two identical dresses. You two could have started a fashion trend of sisters wearing the same dress but no you two decided to fight over something that is so trivial. Me and Clyde wore the same shirt for picture day and we didn't care and don't you dare say that this is a sister thing and I wouldn't understand it. 

Lori and Leni lower there heads in shame as they knew that he was right. If they weren't so stubborn and didn't let their pride get the best of them none of this would be happening.

Lincoln in a upset tone: Luna and Luan I am disappointed in the both of you. You two should have had more common sense then to get yourself caught up with this. I know I shouldn't have put Luna with Lori and Leni with Luan but I was angry and you girls know how I am when my anger takes over.

Lincoln in a upset tone: As for the rest of you I am disappointed in you except for Lily as she wasn't involve with this. 

The Loud sisters were sadden that Lincoln was disappointed with them.

Lincoln: Girls, words can't even describe how betrayed I am feeling right now. I am your big brother/ father figure, it's my job to help solve any conflicts that happens. I know that all of you have different personalities which does cause conflict but to find out that you girls came up with a protocol that doesn't even include me, it hurts knowing that my little sisters came up with a protocol that basically screwed me over. 

Lincoln in a stern tone: By blocking off the kitchen and bathroom this is unfair for everybody else that needs to use the bathroom or the kitchen as we only have one bathroom and one kitchen. If any of you need to calm down use the antic or the basement or better yet come talk to me or mom as we will give you advice on how to solve your conflict as a civil person. 

Lincoln: Girls, Mom and dad told me that because of your actions from yesterday and today. Your being punish for it.

The loud sisters didn't say anything as they felt that they deserve it for how they treated their big/only brother.

Lincoln: The internet is only allowed to be used for school work only and the only TV shows that you all are allowed to watch is the science, history and news channels. You can watch the dream boat and operation desert storm on weekends only.

Lincoln: Lori,your phone is getting parental control and no texting or calling Bobby.

Lincoln: Leni,your fashion stuff is going into the garage.

Lincoln: Luna,your electric, acoustic and your drums are going into the garage as well but you can keep your IPod.

Lincoln: Luan,you cannot do any pranks, tell any jokes and your dummy is going to the garage as well.

Lincoln: Lynn,your sports gear is going into the garage as well

Lincoln: Lucy,your statue of Edwin is going into the garage but you can keep your notebook.

Lincoln: Lana, nothing mud-related and you are going to keep yourself clean.

Lincoln: Lola, you are forbidden from doing any pageants and you can't wear any of your princess dresses.

Lincoln: Lisa, your science stuff is being sold to a nearby college or being put into the garage as me, mom and dad haven't decided on that yet.

Lincoln: Also trips to the mall are not allowed, you girls are grounded for one month, do I make myself clear?

Loud sisters: Yes Lincoln.

Lincoln: Good, before I let you girls go, I want you girls too know that this sister fight protocol might have hurt me emotionally but I will always love you girls no matter what but I want to clarify I am not mad with you girls, I'm just mad of how of the protocol screwed me over and how betrayed I'm currently feeling. Also my trust is something you girls are going to have too earn back as well.Just remember that it is my job as your big brother to solve any conflicts between you girls. Now you girls are freed to go.

The Loud sisters walk out of Lincoln room and get ready for bed.

Lincoln is currently sitting on his bed thinking about the conversation he just had with his sisters.

Lincoln (sighs): I bet Ronnie doesn't have to deal with this.

Author Note: Chapter 2 is finish! Feel free to comment below on what you think of this chapter. I got inspiration for the Loud sister punishment from That Engineer story Syngenesophobia. I highly recommend that you guys or gals read it as it's a very good story despite being a brawl in the family fanfic. Next chapter is going to the fun chapter I mention in the last chapter.  I don't know how much longer I'm going to continue with this story as I have three to four more chapters plan for this story and after that I think this story is going to done with. 

Have a nice day and until we meet again.
