*This all started by Frisk locking the two "rivals" in a room together alone in which she had walked away mere moments later the sound of gaster blasts could be heard as she burst back into the room a moment later to see each of the two at each other's throats*

Chara: Frisk, I know what I did but do I really need to be nice to him?

Frisk: Unless I say no then yes you do PS I say yes Chara

Sans: it's not like I want to be nice to you either brat Chara: You wanna go skeletrash!?

Sans: Bring it! Frisk: GUYS!

*She was genuinely about to slap the two, as she shouted the two looked shocked as she had never been the type to yell at anyone before*

Sans: Geez kid settle down Chara: Now you've done it trashbag

Frisk: NO! You two need to get along or I swear I'll go get mom

Chara: oh geez oh no Sans you idiot

Sans: oh geez oh man, Hey kiddo we'll stop I promise just don't go get Tori

Chara: I promise as well just please don't go get mom

*the two were extremely scared at the thought of Toriel getting involved in their fight as neither of them would make it out unscathed*

Frisk: I'm gonna go make dinner if I heard a single noise that I even suspect to be violent I've got mom on speed dial

Both: okay Frisk just go make dinner

Frisk: I'm gonna keep an ear out just remember that

*She walks down the stairs into the kitchen after she had finished yelling at them*

Chara: I didn't know that she could even get that mad

Sans: That was way out of "Chara"cter for her

Chara: oh my god Sans!

Sans: Oh that was funny Chara

Chara: Ok just a bit funny but we should keep our fighting well non-existent

Sans: only if you apologize for what you did to Papyrus Chara: I'm sorry Sans for the hundredth times this month

Sans: You got a deal brat

Chara: Glad to hear it trashbag, I just don't want to hear her yell at me again

Sans: She was almost as angry as Tori when she sees how we glare at each other

*The two sat there in silence until Frisk came back to get them for dinner, as agreed the two hadn't fought since then except over texts over tiny thing like Chara's sweater not being exactly a good color on her*
