"HUMAN FRISK, YOU AWAKEN." Papyrus noted happily as he walked back to the group. "ARE YOU FEELING ANY BETTER AFTER GETTING SOME REST?"
"No, but…" Frisk started before noticing Toriel. "Mom?"
"Yes my child, Sans told me about what… I'm so sorry, I should have realized it when I saw you. You look so much like her." Toriel explained. "What happened to your sister, my adopted daughter was so sudden and…"
"so what are you going to do now Frisk? I mean considering what happened…" Sans started before closing his eyes. "none of us would blame you if you wanted to just leave the bad memories behind."
Frisk nodded sadly before smiling. "Chara would have wanted me to help you, and there's only one way I can think of to do that. Seeing the king, telling him who I am, and helping free you."
"FREE US, BUT THAT WOULD REQUIRE YOU TO GIVE KING ASGORE YOUR SOUL!" Papyrus cried. "YOU'LL DIE IF YOU DO THAT!"
"are you sure that's what your sister would have wanted? to be fair I want to be free as much as the next monster but this… you don't have to go that far." Sans added only for Frisk to close her eyes again and shake her head.
"Frisk… please reconsider." Toriel requested sadly. "I've already lost two children; I don't want to lose a third."
Frisk just walked to Toriel and gave her a gentle hug. "I love you mom; you've been so nice to me. Maybe… maybe if I can figure out another way but you deserve to be free and I…"
"you want to see her again don't you Frisk?" Sans asked. "you want to be with your big sister Chara don't you?"
"OF COURSE SHE DOES, ANYONE COULD EASILY SEE THAT!" Papyrus exclaimed. "HUMAN FRISK, YOUR JOURNEY AHEAD MAY BE DIFFICULT BUT KNOW THAT YOU HAVE FRIENDS HERE IN SNOWDIN THAT WILL ALWAYS BE WILLING TO HELP YOU."
"Thanks Papyrus, that means more than you know." Frisk smiled before hugging the tall skeleton.
"we already put Papyrus' number in your phone, if you need anything feel free to call. he always picks up." Sans mentioned.
Frisk nodded hearing that before walking over and hugging Sans. "Thank you so much, I promise I'll help you."
"yeah, you sure will Frisk." Sans smiled before the three monsters watched Frisk walk out of the house. "don't worry, I'll look out for you."

Frisk looked ahead as the blizzard started to fade and the temperature started to slowly rise before the ice and snow melted into water.
"This must be what he meant by Waterfall." Frisk noted recalling the young monster with no arms that had told her about Undyne. "So this is where Undyne…"
As Frisk was saying that a spear suddenly struck the ground in front of her as a monster wearing a suit of armor emerged from between the trees.
"Human, your life is forfeit." the armored monster stated coldly causing Frisk to start trembling in fear.
"Are… are you Undyne?" Frisk asked hesitantly as the monster removed her helmet revealing blue scaly skin, an eyepatch over her left eye, and red hair tied in a ponytail.
"Yeah, and I'm going to claim your soul for King Asgore." Undyne declared as a spear formed in her hand before she tossed it to Frisk.
"Wait, please." Frisk pleaded. "I… I have to see King Asgore."
"You and every other human, do you even understand our situation?" Undyne questioned. "We need seven human souls in order to shatter the Barrier keeping us all trapped underground, we have six already."
"Then to break the battier and free all of the monsters all you need is…" Frisk started in realization.
"Exactly, your soul is the last one we need. With it…" Undyne started only for Frisk to look down.
"If you need my soul you can have it, but please I need to see the King… my big sister, she was his daughter." Frisk revealed causing Undyne's eye to widen in shock.
"What did you just say punk?" Undyne questioned.
"The king, he adopted a human child named Chara." Frisk answered as Undyne nodded.
"I know that." Undyne stated before staring at Frisk in shock. "Hold on, you're not telling me that Chara was your older sister?"
Frisk just nodded. "Chara was my big sister, that's why I have to see the king."
"So that's why he was asking about Chara." Undyne muttered under her breath as the spears vanished. "Fine, you can go through Waterfall. I need time to think."
With those words Undyne walked off before vanishing into the darkness leaving Frisk on her own.
"If they need my soul I'll give it to them, but I just… I have to know what happened to Chara first." Frisk whispered before continuing down the path towards Asgore's Castle.

"Are you certain she'll be ok?" Toriel asked anxiously. "Undyne is captain of the royal guard for a reason."
"DO NOT WORRY YOUR MAJESTY. UNDYNE IS ACTUALLY RATHER NICE, I'M CERTAIN SHE WILL…" Papyrus started before the door slammed open revealing Undyne.
"is there something we can help you with Undyne?" Sans asked calmly as Undyne walked in.
"You knew didn't you, that's why you asked about Chara." Undyne accused.
"guilty, then I guess you know?" Sans asked. "about Frisk and Chara being…"
"Sisters, yes I know and now what am I supposed to do?" Undyne questioned. "You know as well as I do that the only way we can free ourselves is with seven human souls. The last one comes walking up to me and yet if I kill her to take her soul…"
"Frisk isn't like the humans from the past." Toriel interjected. "She is a kind girl who only wants to help us. Learning what happened to her sister was hard on her."
"I know that, but…" Undyne started before taking a deep breath. "I'll let her get through Waterfall, but when she gets to the end I'm going to fight her."
Toriel just looked down sadly. "Just promise you won't hurt her."
Undyne nodded. "I'll make it quick, and she'll be with her sister again."
(Undyne has met Frisk and learned who she is but is still planning on taking her soul. Next chapter Frisk will continue through Waterfall and meeting the monsters of the Underground. As always any reviews or critique is appreciated.)
