The sound of water hitting against rocks, echoed and could be heard all over Waterfall region. To many of the residents, the sound was like refreshing music to their ear. Most of the time it was a quiet, murky place to live. For the captain of the Royal Guard however, she spent her day off work, at home and things could get hectic. She's a very passionate and a noisy fish monster, who tends to overreacted in situations. There were many times she would catch her house on fire, because she tends to be a bit careless while cooking. Another time, she decided to play with her giant anime replica sword that Alphys designed. She didn't watch where she was swinging the sword and chopped down a long path of mushrooms, which were used to light the pitch black paths. It took weeks before they grew back and monsters were able to use the path, safely.
The residents of Waterfall didn't have to worry about any disruptions this afternoon. The blue scaled guard was leaving today to spend time with her best friend in the world. A huge smile spread crossed her face, while she thought about her yellow, reptilian, friend, Alphys. Undyne's secret was that, outside she appeared to be calm as a cucumber, but inside her heart was beating in excitement to see her crush. She had been in love with Alphys for many years and she was sure, Alphys felt the same. Undyne would have told her a long time ago but she wanted her friend to be brave enough to finally ask her out. Alphys would be able to gloat about that accomplishment as well and that joy will bring a smile to her face.
The blue scaled monster lost her train of thought as a loud buzzing noise shakes the side of her tight black jeans. She stopped for a few minutes in the damp wet grass for a while. She reached into her pocket and pulled out her phone. Glowing brightly on the phone display was the name, Alphys.
"HEY ALPHY!" her voice excitedly echoed as it bounced off the cavern walls. On the other side of the phone, she could hear a voice scream, then banging noise of the phone being dropping on hard floor. "Are you alright, Alphy?…Sorry I didn't mean to scare you. I'm almost there to Hotland. Whats up! I was going to grab snacks at the MTT food court before heading over..." Undyne's voice resonated a happy tone, while she started swinging her free arm in a jogging motion as she picked up speed.
In her ears she could hear gasping panicked voice, repeating her name over and over. "Clam down Alphy, before you give yourself a mini heart attack….There's someone importation you want me to meet? …..Alphy!" she cried as she heard the phone drop again. Undyne kept calling her name as she started to run as fast as she can without tripping on muddy dirt under her feet. Sure Alphy sometimes went into an embarrassing frame of mind, but this time it seemed like she was in trouble.
Out of no where, an unknown female voice came over the phone, telling her, Alphy was alright she just passed out. This caused Undyne to dig her feet into the dirt as her body slid into a quick halt. Being the captain of the Royal Guard, her job was to go throughout the underground, from time to time, checking up on concerns. She thought she knew every monster, but she never heard this voice, in her life. "I DEMAND YOU, TELL ME WHO YOU ARE AND WHAT YOU DID TO ALPHY!" She yelled into the phone, holding it out in front of her.
"Arial?" she repeated, baffled by this unrecognizable voice. "I DEMAND YOU TELL ME YOU'RE RELATIONSHIP WITH ALPHY NOW!" She screamed at the top of her lungs while running through the cave like a mad women. "TELL ME…" she stops speaking as she heard a clicking noise on the phone and everything goes silent.
She clings the phone hard into her chest, as she started running into turbo mode. Scenes before her became a messy blur of colors. She had to hurry to Alphy's laboratory. This woman may be holding Alphy for ransom. Then again her friend told her that she wanted her to meet someone importation to her. Could Undyne be wrong and Alphy was in love with this girl, Arial and not her? "NO" she screamed, shaking hard from the thought. She had to hurry, Alphy or her own heart, could be in danger.
