Frisk is thrown backward as Chara's blow hit her. Her arms were crossed to protect her face but the rest of her body was receiving blow after blow.
Chara! Stop! She shouts as Chara approaches.
Why Frisk? Ready to play my way? Chara asks.
Never! Frisk yells at her. You heard Sans, I have to find a way to take my body back! And stop you!
Well then, if your plotting against me, I won't stop. She skips forward to hit Frisk again. Frisk dives to the left and Chara slashes the wall. Chara turns and attacks again. This time Frisk grabs the knife blade, it cuts a gash in her palm but she holds on.
Chara please! Why do we have to kill everyone? Why do we have to reset? Don't you love them? We spared them all together! Don't you like them as much as I do?
I...I do like them.
Then why? Why kill them?
Isn't that what you do with people you love? To protect them from other harm? To protect against humanity? Against people like me?
Chara no! It doesn't have to be like this! Facing humanity is just a part of living! Everyone here loves each other! And they loved me to. But now...now they don't remember me. You saw how Sans took the hit for his brother even though he has... had low HP! You saw how Toriel fought you when she found out you killed all the monsters in the ruins! We can do this together! Please! Let's be partners again! Frisk holds out her hand to Chara. Chara still has both hands on the knife handle. She looks angry and confused, as if she doesn't understand where Frisk is coming from.
You... don't remember do you? She asks, instead of taking Frisk's hand. We killed everyone together multiple times. It was a lot of fun, being together and doing it. Sans will never trust you, he knows what do did! What you do! Flowey is easier to manage, one True Reset and he's good as new.
Your right... Frisk says. Your right about Sans will never forgive me. Honestly, I don't forgive myself. But Chara please! We can still be together we don't have to do it like this!!
Sorry! Chara says, shrugging. But this run is to interesting already. Catch you on the flip side Frisk! Chara lunges forward.
Chara wait- Frisk says. But instead of killing her, she jabs the Continue button with her fist.
It'd be very inconvenient if you were dead, I realize that now. Chara says, as she starts to fade away. I still need to use you! Well, bye for now! And she disappears.

   Chara walks across the silent, dust strewn grounds of Waterfall. Each step causes a pile of dust to rise up and disappear into the air. Chara trudges across the terrain, any monster daring to fight her dying with a clean slash from her knife. They couldn't hide forever, and when she found them they had no choice but to fight. Fleeing was not an option at this stage. As she walks across a bridge with pillars to one side, spears come up and block her path. Chara smiles, expecting them. But she wasn't expecting Undyne herself to slam on the bridge after them.
   "You!" She growls as she see's Chara. "I can't believe you." Chara tilts her head slightly to one side, still smiling. "What type of selfless jerk would kill for fun! Monsters fight humans because it means our freedom, but you! You kill them because you can, because they're in your way." Undyne takes a deep breath, waiting for Chara's response.
   "Well it's true I don't have to," Chara started, her finger tracing the knife blade. "Why don't we think of it as a sport? You don't have to do a sport, but you can."
   "Killing isn't a sport, punk!" Undyne shouts. "And thanks to you, Papyrus can't do anything! He can't cook because he starts crying into the noodles or something, saying how much Sans liked spaghetti! And his battle training? You can forget that! He can't even throw a bone properly! My student, my friend! You broke him! Well guess what! I'm going to break you!" Her mouth curls into a sneer, and she trusts herself forward to stare right into Frisk's face. "I'm going to break every bone in your body! And you better be prepared punk, because I'm gonna go all out!" And she jumps off the bridge and onto the raised platform above Chara. The spears disappears as Undyne does into the darkness. Chara isn't fazed. She's fought Undyne before, and it's Frisk's body that's she's threatening to hurt, no Chara's. She continues on, the fun prospect of Undyne's fight awaiting her.

   "I better go." Undyne says, her armor in place, heading out of the lab.
   "U-Undyne don't!" Alphys says, placing an arm on Undyne's. "Y-you know what t-that thing did to S-Sans!" In the corner of the lab, Papyrus was sitting, cradling Sans' jacket, tears falling onto the material.
   "That's exactly why I have to go!" Undyne growls, turning around to face Alphys. Alphys cowers. "Do you think that kid is going to stop if we, if I step aside? Someone's got to step up and I'm planning it to be me!"
   "But Undyne! W-what if the h-human k-kills you?" Alphys asks, sweat running down her face.
   "I am more then willing to die if it can protect all of monster kind!" Undyne shouts. "And it's not just for monsters anymore! It's for humans too! If that thing gets past me they'll kill everyone!" She turns away from Alphys again. "Just remember, if I do die...then tell everyone to evacuate."
   "U-Undyne, d-d-do you think you w-will d-die?" Alphys questions. Undyne pauses and turns around again.
   "Of course not Alphys! I'll kill that kid!" She looks up from Alphys to see Papyrus still in the corner. "Hey, Papyrus." Undyne says, walking over to him and putting a hand on his shoulder. He looks up, his face tear stained.
   "W-what is it?" He mutters, clutching Sans' jacket closer to his chest.
   "You're still the greatest monster ever." She bends her knees down so she's on Papyrus' level. "I loved him to, y'know. I love all of my friends and just because he's...well...just because he's not here doesn't mean we can't still love him. I'll get revenge for him, I promise!" She gets up, and walks to the entrance of the lab without further interruptions. She continues along Hot Land to what surely will be, her death.
