Undyne grabbed frisk by the hand and lead her to her house. It took a little while but then eventually got there.

Undyne's house was so well decorated. She had beautiful velvet blinds covering her window. Pictures on the walls and flowers everywhere. It was a little weird. It was a nice change for Undyne even though that isn't the Undyne that they know.

"nice little get up you got here." Sans picked up a flower and smiled it.

"Thanks." Undyne walked over to her piano and began playing. The title of the song was loves sorrow. She played with protection and feelings. It was beautiful.

Frisk began to weep. Once the song was over Undyne noticed that frisk was crying. Undyne removed her fingers from the keys Imideily.

"I'm sorry I didn't think that this wouldake you upset... I'm sorry." Undyne looked down at the floor.

Frisk shook her head and told Undyne that the song was one of the most beautiful things she has ever heard.

Undyne looked at Frisk only to be surprised with a hug and warm tears. Undyne patted Frisk's head until she let go.

"geese I knew that you were good at doing things but I never thought you would be a musician." Sans just looked at Undyne with pure astonishment.

"I love music and I enjoy making it so I tought myself a few songs." Undyne got up and stepped into the kitchen. Removed three glasses and pure them with tea. She handed one to Frisk then Sans.

"OK let's get one thing straight I know I a sexy bag of bones but Im not into you. Just a heads up." Sans looked straight at Undyne.

"No it's nothing like that I don't have a crush on you or anything. I actually already like some one." Undyne looked down to her lap with her face glowing red.

Frisk pulled on Undyne's shirt and asked her who it is.

" No I can't tell you."

"Come on what's the harm in telling us?"

Undyne stayed wordless for a while. Then sighed" Her name is Alphys"

"I know it."

"How did you know?!"

"I felt it in my bones." Sans winked at Frisk and she giggled at a response. "Well me and the kid are going to go see her soon actually."

"Why"

"Well I guess you could say to try and figure out how to get to our universe."

"What do you mean? Don't you live with Papyrus?"

"Well yeah but a different Papyrus. Me and the kid are from a different world. One where the baryer is broken."

"Wait what!?so your saying that in your world the baryer that is separating us from the humans was broken! How?"

Sans nudged Frisk forward. "by this little kid here."

"What! Really! Do you think you could do that for us."

Frisk shuged.

" What do you mean? Why can't you?"

"Well you see there were certain circumstances in the matter that aren't happening right now. So it's a little difficult to tell if Frisk can or not."

"Oh I see. Sorry Frisk."

Frisk waved her hand to Undyne showing that there was no hard feelings.

"Thanks"

Frisk smiled.

"So anyways the baryer is broken in our world and I tried to teleport me and the kid to Grilby's. Ya know for like one last look before leaving forever."

"yeah I get it. I'm assuming that when you tried to teleport you some how wound out here."

"That about sums it up."

" I think Alphys might know what to do. You should go and ask her."

"That what we are going to do but we kind of got distracted."

"Oh I'm sorry. It just that I have to try to do my job." Undyne began curling a strand of hair around her finger.

Frisk tells Undyne that they understand and that it is okay.

Frisk and Sans finish their tea and made there way. Before leaving Frisk waved Undyne good bye.

Sans and Frisk made there way out of waterfall and in to hotland. Well of course not with out running into other monsters that wanted to fight.

Finally they made it to Alphys' lab. Sans and Frisk looked at one another and opened the door and walked in.
