*Frisk sees Sans in front of the resort*
Sans: Hey. I heard you're going to the Core. How about grabbing some dinner with me first?
Frisk: Ya.
Sans: Great. Thanks for treating me. I know a shortcut.
*Sans leads Frisk to the side and they teleport in the restaurant*
Well, here we are. So, your journey's almost over, huh?
Frisk: Yep.
Sans: You must really want to go home. I know the feeling. Maybe sometimes though, it's better to take what's given to you. Down here you have food, drinks, and friends. Is what you have to do really worth it? Ah, forget it. I'm rooting for you, kid.
Frisk: Thanks Sans.
Sans: Let me tell you a story.
Frisk: Sure.
Sans: So, I'm a sentry in Snowdin forest, right? I sit out there and watch for humans. It's pretty boring. Fortunately, deep in the forest, there's this huge locked door. It's perfect for practicing jokes. So, one day, I'm knockin em out, like usual. I knock on the door and say knock knock. Then suddenly, I hear a woman's voice from the other side. "Who's there?" So naturally I respond "dishes." "Dishes who?" "Dishes a very bad joke" Then she just howls with laughter like it's the best joke she's heard in 100 years. So I keep em coming and she keeps laughing. She's the best audience I've ever had. Then, after a dozen of em, she knocks and says, "Knock knock." I say, "Who's there?" "Old lady." "Old lady who?" "I didn't know you could yodel." Needless to say, this woman was extremely good. We kept telling each other jokes for hours. I had to leave eventually. Papyrus gets kind of cranky without his bedtime story. She told me to come by again. So I did. It's kind of our thing now. Telling bad jokes through the door. It rules. One day, I noticed she wasn't laughing much. I asked her what was wrong. Then she told me something strange. "If a human ever comes through this door, could you promise me something? Could you watch over them? Protect them?" I hate making promises. And this woman, I don't even know her name. But, someone who likes bad jokes has an integrity you can't say no to. Do you get what I'm saying?
Frisk: Not exactly.
Sans: That promise I made to her... You know what would have happened if she hadn't said anything?
Frisk: Um, no...
Sans: Buddy. You'd be dead where you stood.
Frisk: Um...
Sans: Hey, lighten up, bucko! I'm just joking with ya. Haven't I done a great job protecting you? I mean, look at yourself. You haven't died yet.
Frisk: True. You have done a good job.
Sans: Heh. Well, that's all. Take care of yourself, kid. Someone really cares about you.
*Sans leaves and Frisk moves on out of the restaurant to a shop in the hotel*
Burger pants: Welcome to MTT Brand Burger Emporium. Home of the famous glamburger! Sparkle up your day!
Bratty: Hey! Check it out!
Catty: Ya! Check it out!
Bratty: So, like, What's up?
Catty: You should buy ALL our stuff!
Frisk: I guess I'll take a bag of chips.
Catty: Bratty! We're going to be rich!
Frisk: Um, ya... Bye.
Bratty and Catty: Like, later!
*Frisk goes back into the resort then goes through the door of the Core and goes through the hall. They see two doors and an elevator. Alphys calls*
Alphys: Ready?! This is it! Take the elevator to the top of the core!
*Frisk tries to use the elevator but it doesn't work*
What? The elevator should be working... Well then, let's go to the left.
*Frisk goes to the left*
Ok, you should be able to make it through here.
*Frisk goes through the halls door to see laser*
Looks like you can't proceed until you hit the switch. But those lasers when you do. Um, They'll come in the order orange orange blue. Got it?
Frisk: Yep.
*Frisk moves through the lasers in the order Alphys said. They get hurt by the lasers*
Ow!
Alphys: Oh my god! Are you hurt? I'm- I'm so sorry. I gave you the wrong order. Everything's going to be fine. Let's just keep heading to the right.
*Phone call ends. Frisk heads to the right to the next room with cross roads. Alphys calls back*
A cross road? Um... Try heading to the right!
*Frisk heads to the right*
More lasers? Ok... I won't mess up this time. I'll just deactivate the lasers and let you through. Wait, they're not turning off. I can't turn them off. It's ok! I have this under control! I'm just going to turn off the power. Then you can walk across. Ok, go!
*Frisk goes through the lasers*
See? I've got everything under control. Everything's under control!
*Phone call ends. Frisk walks to the next room to find another roadcross room. Alphys calls*
Ok! You should... You should... I- I don't know.This doesn't look like my map at all. I'm sorry... I... I have to go.
*Call ends. Frisk moves on to the left to find a puzzle. They solve it and move on back to the beginning of the crossroad. They then go up to press the switch. They then go back to the beginning again and go to the right to encounter a door next to an elevator. They go through the door to see Mettaton.*
Mettaton: Oh yes! There you are, darling! It's finally time to have our little showdown. It's time to finally stop the malfunctioning robot. NOT! Malfunctioning?! Reprograming?! Get real! This was all just a big show! An act! Alphys has been playing you for a fool this whole time! As she watched you on screen she grew attached to your adventure! She wanted to be a part of it! So she decided to insert herself into your story! She deactivated puzzles, disabled elevators, and enlisted me to torment you! All so she could save you from dangers that didn't exist! All so you'd think she was a great person! She's not! And now, it's time for her final hour! At this moment Alphys is waiting outside the room! During our battle she will interrupt. She will "deactivate" me, saving you! She will be the heroine of your adventure! You'll regard her so much! She will even convince you not to leave! Or not! I've heard enough of this predictable charade! I have no desire to harm humans! Far from it actually... My only desire is to entertain! The audience deserves a good show, don't they? And what's a good show without a plot twist!
Alphys: Hey! What- What's going on?! The door locked itself!
Mettaton: Sorry folks! The old programs have been canceled! But we've got a final one that will drive you wild! REAL DRAMA! REAL ACTION! REAL BLOODSHED! On our new show... "Act Of The Killer Robot!"
*Battle starts*
Mettaton: Yes. I was the one that arranged the cord! I was the one that hired everyone to kill you! That however was a short sided plan! You know what would be 100 times better?! Killing you myself!
Frisk: Why do you want to kill me?
Mettaton: Listen, darling! I've seen you fight! You're weak! If you continue forward Asgore will take your soul! And with your soul he will destroy humanity!
Frisk: But I think I can handle him. I've handled everyone else.
Mettaton: But if I get your soul I can stop Asgore's plan! I can save humanity from destruction! Then using the souls I can cross through the barrier and become the star I've always dreamed of being! So many humans will watch me!
Frisk: But you're already a star down here.
Mettaton: Glitz, glamor, I have it all! So what if a few people have to die? That's show business baby!
Frisk: But it's not right.
*Alphys calls*
Alphys: Um, I- I can't see what's going on but, don't worry. Don't give up, ok? There's one last way to beat Mettaton. It's... This is a work in progress, so don't judge it too hard. You know how Mettaton always faces forward? That's because there's a switch on his backside. So if you can get him to turn around, um, press the switch. He'll, um, be... Vulnerable. Well, gotta go.
*Call ends*
Frisk: Hey Mettaton. There's a mirror behind you.
Mettaton: Oh, a mirror? Right. I have to look perfect for our great final.
*Mattaron turns Frisk flips his switch*
Did you... just flip... my switch?
*Mettaton transforms into a human bot*
Oh my... If you flipped my switch that can only mean one thing. It means you're desperate for the premier of my new body. Oh, how rude... Luckily for you I've been aching to show this off for a long time. So as a thanks, I'll give you a handsome reward. I'll make your last living moments... Absolutely BEAUTIFUL!
Frisk: What do you mean by that?
*"Death by Glamor" song by Mettaton*
Mettaton: Oh, look at these ratings! This is the most viewers I ever had! Now, one lucky viewer will get the chance to talk to me before I leave the Underground forever! Let's see who calls first!
Caller 1: Hello.
Mettaton: Hi! You're on tv! What do you have to say on our last show?!
Caller 1: Hi, Mettaton... I really liked watching your show... My life is pretty boring, but... seeing you on screen brought excitement to my life... vicariously... I guess this is the last episode... I'll miss you Mettaton... Oh, I didn't mean to talk so long...
*Call ends*
Mettaton: No, wait! Pl- They... They already hung up... I'll take another caller!
Caller 2: Mettaton! Your show made us so happy!
Caller 3: Mettaton! I don't know what I'll watch without you.
Caller 4: Mettaton! There's a Mettaton shaped hole in my Mettaton shaped heart.
Frisk: They love you Mettaton!
Mettaton: Ah... I see... Thank you all so much. Darling... perhaps, it might be better if I stay down here for a while... Humans already have stars and idols, but monsters... They only have me. If I left, the Underground would lose its spark. I'd leave a void that can never be filled. I think I'll delay my big debut... Plus... You've proven to be very strong. Perhaps even strong enough to get past Asgore. I'm sure you'll be able to protect humanity. It's all for the best anyway. The truth is that this energy form consumption is inefficient. In a few moments I'll run out of battery, and... I'll be alright. Knock 'em dead, darling. And thank you everyone. You've been a great audience...
*Battle ends. Alphys walks in*
Alphys: I managed to open the locked door. Are you two- Oh my god! Mettaton! Are you... Thank god! It's just the batteries. If you were gone, I would have... I would have... I mean... it's not a problem... He's just a robot. If you messed it up I could just build another. Why don't you go on ahead? I- I just need a moment.
*Frisk goes ahead. Alphys catches up down the hall*
Sorry about that. Let's keep going.
*Frisk and Alphys keep walking*
So... You're about to meet Asgore, huh? You must be... Pretty, um, excited about that, huh? You'll finally be able to go home.
*Frisk is about to get on the elevator*
Wait! I was... I was just going to say goodbye and... I can't take this anymore. I lied to you. A human soul alone isn't strong enough to cross the barrier. It takes a human and monster soul. So, if you want to go home... You're going to have to kill Asgore and take his soul...
Frisk: What?
Alphys: I'm sorry.
*Alphys leaves. Frisk takes a breath and is about to get on the elevator but stops when they get a call from Undyne*
Undyne: Hey! This is Undyne! Shut up Papyrus! This was YOUR idea! Human! You have to deliver something for me! Please? I'm at Snowdin in front of Papyrus's house! See ya punk!
*Frisk goes to Papyrus's house to see him and Undyne. Frisk walks up to Papyrus*
