Chapter 4

I say "omg stop lieing to me". He says " I'm not and stop laughing "! I say" ya ya ya and I'm the present of the United States". He growls and says" I'm the older brother just ask Frisk"! I say" fine which one is the older brother "? Frisk points at Sans and says" him". Sans walk's over to the couch and says " told u". I say " oh go fuck ur self ". I feel a sharp pain in my side and look to see that Frisk elbowed my side. I was going to say something when Pap open's his door and comes downstairs and says" humans I have made my choice and I have decided your fate will let u both live but the new human must fight me or I kill u and take ur souls to Asgore". I say to Sans" this is not over ". Stand up and say " deal ". I walk outside and prepare for the fight.Pap walk's out and the battle began. I dodged all of the attacks and spared Pap and finally he spared back and I won.

Pap: U have impressive fighting for a human girl

Me: Hey! Just because I'm a girl doesn't mean I can't fight and thx I guess

Pap: U and ur brother may live and know that I barely ever spare anyone so your lucky to be alive.

Me: WTF whatev's fuck this shit I'm out. Come on Frisk we r leaving

Frisk: Where?

Sans: Ya where?

Me: Mom's house

Frisk: K bye Sans! Bye Pap!

Pap: u can't just leave

Me : Why not?

Pap: Because the monster's think ur dead so u can't just walk thru town.

Me:Oook so how can we leave

Pap: Put these on* hold's out two leach's*

Me: I'm not putting on a fucking leach 

Sans:* walk's up from behind*" Why not~?

Me: fuck off Sans no one was talking to u 

Pap: well human if u want to leave so badly u'll put them it on so it looks like ur our prisoners

Me: Fine* take's it and put's it on* 

Sans: U look good in a leach

Me: shut up and go fuck ur self

We all start walking in tell we get to the last puzzle.

Me:* take's off leach*So much better. Well bye
