As you, Sans, and Undyne walked into Snowdin, Papyrus, Frisk, Toriel, and another monster, a small dinosaur child with no arms were waiting for you. "HUMAN- OH I SEE YOU HAVE MET UNDYNE! ARE YOU FRIENDS?" Papyrus says, walking over to you and giving you a hug. "Haha, uh..something like that. I came back to say 'Goodbye'. Bye guys. I'll miss you" you say, wiping back tears. Toriel looks sad, but she doesn't shed a tear. Frisk signs to you "What about Cait?" You shrug "I d-don't know Frisk. I-I'll have to leave her too." You say, holding back tears, thinking of Caitlin. 'What would she say, if she knew I was willingly walking to my death?' You think. "I'm gonna go to the king. Get all y'all out of here, for good!" You say, hugging the group. Undyne walks behind you, and puts a spear on your shoulder. "Time to go PUNK!" she says, grabbing your (f/c) hoodie's hood. "Bye guys. Frisk, Mom, tell Cait I said hi, okay?" You say, wiping a tear out of your eye. "Undyne, I'm coming with you. If you thought this was an opporTUNAty of me, you were wrong" Sans laughs, catching up to the fish lady. You wave your last goodbye to your goat-mom, 2 of your best friends, and the monster child you haven't met yet.

As you walked through Waterfall, Undyne seemed to get antsy. She was rambling about 'Alphys.....Ice Cream...... Guards......Souls' you walked ahead, getting more and more bored as time dragged on. "Are we almost there?" you whined. Undyne stopped mumbling and nods. "Where are we going?" You ask, stopping, and looking around. You notice a sign saying 'Welcome to Hotland' you see the difference between Waterfall and Hotland. "Dr. Alphys's lab. She'll help us get you to the king, Asgore Dreemurr." Undyne says, with a faint blush dusting her cheeks. "Ooohhhh somebody has a crush!" Sans laughs. You see a blue bunny, standing next to a cart. It looks like ice cream vendors back on the surface. You walk over, get 4, and give one to Sans, one to Undyne, and one for you. The 4th one is for Alphys. You run ahead, telling Undyne to race you. As you run off, you bump into a monster. You look at the monster. "Oh, uh, sorry, a-are you okay?" you ask, helping her up. "H-huh? Oh, yeah I'm fine. Just heading to my sister's work. Gotta h-help her y'know?" She laughs. "Cool, hey, we're going the same way, wanna go there together?" you ask her. "S-sure. By the way, I'm Alphyne. A-and you?" she asks you. "I'm (Y/N). Oh, C'mon. Undyne's coming. I'm racing her to a lab. Do you know where Alphys's Lab is?" you ask. She looks shocked, nods and explains that Alphys is her twin. "C'mon, we gotta go before Undyne catches up!" you laugh, grabbing her hand, and taking off.

As you ran to the lab, following Alphyne, you heard some music. "O-oh, Undyne's getting closer. That's her music, Spear of Justice. Come on!" Alphyne says, tugging on your arm. You run slightly faster, and you see a large, white building that has a sign saying 'LAB'. "Alphys! Open up sis. Undyne's gonna be here in a bit. And I brought a human. H-her name is (Y/N)." Alphyne says, pounding on the door. "O-oh o-okay. I-it's open. Come on in." You hear. The door opened, and you see a monster almost identical to Alphyne. "O-oh h-hi. I'm Alphys. You m-must be (Y/N). W-where's Undyne?" She asks. "Back there somewhere. I raced her, and that's when I met Alphyne." You say, looking back and seeing Sans and Undyne sprinting towards you. "O-oh there she is. C'mon, I'll hide you (Y/N)." Alphyne says, grabbing your hand, and taking you to a hidden spot. "O-oh h-hey U-Undyne. W-what b-brings you here? D-do you wanna w-watch A-anime?" Alphys stutters. 'Is she nervous? OMG does Alphys like Undyne?' You think to your self. "I'm bringing a human to Asgore. Have you seen them?" Undyne asks, walking closer to your hiding spot. "N-no I-I haven't." Alphys stutters. Alphyne laughs, and pulls out a few Anime disks. "W-wanna watch some anime, Undyne." She asks. Undyne grunts, and you hear the television make a noise. "Alphy, do you have any of that Ice Cream left?" You hear Undyne ask. "Y-yeah, in that cabinet." She replies. You hear Undyne's footsteps getting closer and closer. You prepare yourself to see Undyne's face looming over you. The door swings open, and Undyne lifts you up. "There 'ya are punk!" She says, and you black out for what feels like forever.
