Soon music was heard as Pearl and Steven made it to the river stream with little blue Echo Flowers near the river. Pearl stopped as she let go of Steven's hand. Steven look up to see Pearl was somewhat in a trance or something when she heard the music. Steven call her name but she didn't respond till he yell her name making her turn a little towards him. Steven look up at Pearl and asked "what's wrong?" Pearl began to get tear up as she sat down by the river, Steven joined by her side. Pearl finally responded to Steven, "I remember that music, the same song that Rose had sang after the battle." Steven look up at Pearl and ask "mom sang this song." Pearl nods as she looked in a water of a reflection of herself in the water. Steven soon turn to see the flowers began to sing a soft melody. Their blue colors were flickering on and off every now and then as they sang a soft tone.

Deep down we can hear your inner voice.

What will it tell us?

The deepest shallow of this cold mind.

You will be the one to help us free…

Will you save your friends, show them the world above?

Two side are playing a tough game.

A decision you both must choose.

Will you set him free and show him mercy?

The decision is up to you, this will be up to you.

Show her the real mercy to see what this all means.

What will you do?

That's up to your inner voice…

Steven turn to see Pearl didn't hear the song that the Echos Flowers had sang. What was that all about? Was the flowers giving some sort of message? Steven didn't know, he saw Pearl crying as she put her hands over her face. Steven tilts his head and asked "Pearl, what's the matter?" Pearl sighs as she turn to Steven but with her cheeks running with her tears and her eyes are all watery. "I don't even know how to even help if I can't even get us out of here." Steven was shocked to hear this. He wonder if the Echos Flowers was giving her a message as well. He put his hand over her's and said "I know you Pearl, you're a strong Pearl I ever known. You just have to believe and have hope to get out of here." Pearl wipe her tears with her arm saying "you're right, Steven."

She stood up along with Steven and said "I can't give up. We have to believe that we can get back home to the others." Steven smiled and the two of them continue to walk through Waterfall. The music began to die down some but still can hear it. Steven began to walk in front of Pearl as he looked around to see more Echos Flowers all over the place. He didn't watch where he was going when he began to come up to a small brown and yellow lizard creature with only a tail and two feets, no arms. The lizard creature too didn't see Steven coming towards him. Pearl happen to saw the lizard kid and saw Steven walking right to it. She cried "Steven, watch out!" Too late, Steven bumped into the lizard causing the lizard kid to fall down on his face. Steven was able to balance himself from falling. Pearl ran up to make sure Steven was okay.

The lizard kid use his tail to get himself back up and turn to say "hey, what's the meaning here? You nearly had me hurt." Steven turn saying "I'm sorry, I didn't see you there." The lizard kid look at Steven and ask "wait, are you a kid?" Steven nods saying "yeah, I'm Steven and this here is Pearl." The lizard kid smiled with his buck teeth showing, "cool, I'm Monster Kid. You can just call me MK for short." Steven said with a smile "nice to meet you MK." Steven was about to put his hands out to shake but saw MK didn't have any arms so he put his hand behind his back. MK said "are you two looking for Undyne?" Steven and Pearl was about to ask who that is but, MK began to brag about Undyne. So they continue to walk while MK just kept on bragging. Steven kinda enjoy listening to MK while Pearl was getting sick of it. She just wish they could get rid of MK and continue on without all this bragging about Undyne.

MK soon had to leave the two be while he go get lunch. He ran home though he fell on his face couple times. Pearl said as she and Steven began to walk, "glad to see him leave, one more bragging I was going to go buzzirk." Steven laugh saying "I was enjoying it." Pearl sighs saying "I figured you were." They happen to look up to see fake stars in the sky. Steven said "I wonder why there are fake stars up there." Pearl didn't respond. She thought to herself "just like the real stars at home." Just then they heard a voice saying "kinda lovely aren't they." Steven and Pearl look ahead of them and there stood Sans in front of a small telescope. "I knew you two would show up here." said Sans. Steven ask "how long have you been here?" Sans shrugs saying "bout two or three minutes." Steven smiled at Sans while Pearl began to look at the telescope.

Sans saw Pearl curiosity with the telescope that he asked her if she wants to look through it. Pearl nods as she put her eye into the piece to look through the telescope. There was nothing to see at all, she look at Sans saying "I can't see anything in that." Steven look at Pearl's right eye to see a red circle around her eye. Steven began to laugh out loud while Sans trying his best to not laugh. Pearl look at Steven and ask "what's so funny?" Steven said "look at your eye." Pearl came up to the river and saw her reflection in the water. She saw the red circle around her eye, she turn to Sans and ask "did you do that on purpose?" Sans began to laugh out loud, he and Steven couldn't help but laugh. Pearl gave an irritated sigh as she went back to the river to wash away the red circle.

Once she got the red circle off around her eye she came back to see the two still laughing their heads off. Pearl shook her head and came up to them saying "I hope you both had you laughs." Sans was able to stop his laughing to speak "aw come on, ya know that was good and you're smiling at that." Pearl sighs saying "yes, and I hate it." Steven had finally stop laughing as he stood up to face Pearl. Pearl shook her head as she said to Sans, "you did got me there though." Sans nods saying "don't worry. I did that same trick to Paps and I still do it. No matter how many times I done it." Steven laugh saying "I bet he too look funny." Sans nods saying "he sure does, but he's the coolest bro ever." Sans look at Pearl and said "watch out for Undyne." Pearl tilts her head and was about to ask when Steven interrupt, "are you coming with us Sans?" Sans shook his head, "nah, gotta get back to read a bedtime story to Paps. He get's cranky if he doesn't hear his bedtime story." Steven said "oh well it was great seeing you." Sans nods saying "yup, I'll see you both again soon."

Sans was about to leave when Pearl stop him. Steven however was gazing back up at the fake stars not hearing Pearl or Sans talking. Sans turn to Pearl and ask "what is it?" Pearl ask "Sans, who is this Undyne? You did told me that you were going to explain what Greater Dog mean about the king." Sans sighs saying "well I kinda mention it to Steven when you were dancing at Grillby's. Anyways first thing Undyne is the leader of the royal guards. She won't be able to harm you since you are a gem. I know she'll figure that out pretty quickly but since Steven is half human, she'll be able to take his soul and give his soul to Asgore, king of the Underground." Pearl listen as Sans explain to her about the six souls were captured and brought to Asgore. Only needed one more soul to break the barrier so the monster can be free. Once Sans finish Pearl ask "so why is the king doing this to these innocent children?"

Sans sighs saying "well it's a bit more heartache and kind of a revenge. I'll explain that to you more before you meet the king. The only way to get out is to face him yourselves." Pearl had a bad feeling that's what Sans was going to say. She thought to herself "all these monsters only wants to be free. I wonder if there is another way for them to break free without those souls." Sans said as he was ready to snap his finger, "welp, gotta go home now. You two better keep moving. Remember my warning about Undyne. Don't let her take Steven's soul or it's all over." Pearl nods saying before he snap his finger to disappear "I appreciate all your help, Sans." Sans nods his head and soon was gone in a flash. Pearl sighs as she walk up to Steven saying, "Come on Steven, let's keep going." Steven ran up beside Pearl as he was having a good time in Waterfall.
