You moved inside San's and Papyrus's house, throwing Undyne's phone onto the couch. You went to the kitchen and pulled a knife out of the drawer. As your reflection shimmered back at you, the door opened steadily.
"U-undyne?" She said quietly. You moved out of the kitchen and stepped toward her friendly.
"Alphys! Long time no see!"
"W-where's Undyne...!"
"Hmmm....you wanna see her?"
"Y-yes!"
"Alright..." you pulled out the knife and move toward her quickly.
She screamed for Mettaton and he opened the door with surprise. Your hand was on her throat and your knife was extended.
"Warn...them..."She muttered. With a quick stab, you felt her turn to ash and turned to glare at Mettaton. He ran out and darted away.
You would get him.
