UnDEADiable Love (G!SansxFrisk) [completed]

Part Eleven: Escape

Sans threw himself backward, towards Gaster, tripping him and making him loose grip of the bone attack. He ran towards me, grabbing my hand and then teleporting us out of there.

As we arrived outside of the lab, a strange place to teleport, Sans picked me up and started running. I heard a mental door crash open and narrowly saw Gaster chasing us.

"S-Sans," I tried to warn him.

"I know. Don't worry, he has a lot of enemies. Especially one particular fish, who isn't afraid of killing." He had a strange tone to his voice.

I kept an eye on Gaster as we kept running. He was shouting things to try and get us to stop, to falter our hope. But I was determined to stay alive, to get through this, and I'm sure Sans was too.

We soon ran into a place full of blue flowers and waterfalls, which had a calming environment, despite the murder bent monster following us.

Sans took a few strange turns and ran faster than other, arriving at a house soon enough. A tall fish-lady opened the door, "What's up Sans. .?" She narrowed her eyes at me.

"Don't focus on her Undyne, focus on him!" He pointed to Gaster, who appeared around the corner.

"Oh, calling for help, huh, Sans? A weak move."

"Not a weak move," Undyne said, "A smart move."

She summoned a blue spear into her hand, taking a defensive stance.

"You will do no more harm, Gaster! I have let you roam the Underground for too long!"

"Save the speech for your death, Undyne." He raised his hand, summoning multiple colors of bones and what had to be hundreds of bone attacks.

"A little scared, Gaster?" She taunted him with a toothy grin.

"Of course. You are one of the strongest in the Underground, but not the most intelligent." He taunted back, both of his eyes flaring purple.

"I don't need intelligence, I need strategy, skill, and strength." She summoned multiple spears.

"Do your best, then."

The fish charged Gaster, spear at hand, battle cry sounding. He dodged to the side, sending some of his attacks at her back. She blocked them with her spear, sending some of her spears towards him.

This went on for a few minutes before they were both tired.

"You put up a good fight for an old man." Undyne continued to insult him.

"You put up a good fight for a walking fish." Gaster shot back.

Undyne gave an out of breath laugh, "Well, I hope that's all you wanted to say. Because it's my turn and, well, I'm going to play dirty for just a moment."

I gasped as a blue spear shot through his ribs. And then everywhere else, until he was slowly turning into what appeared to be dust. . .

"Good fight, Undyne. . . Good fight. . ." He slowly turned to look at Sans and I, "Have fun waiting for the surprise." He gave us a smug grin before fully turning into dust.

Undyne stood up, brushing the dirt off herself.

"You're welcome." She said before going inside, closing the door without another word.

I felt a sharp pain in my neck, stumbling a little bit.

"Frisk, what's wrong?" He asked, his arms out in case he needed to catch me.

"I-It's my neck. I-I'm getting random pains and I-I don't know why." I explained to him, rubbing my neck where I was injected.

It was indescribably painful.

"How—Is there anything that I can do to help?" Sans asks, sounding worried.

"I-I don't know."
