"the last human soul." undyne said she then picked up the baby "now all monsters can be free with this last soul." but something wasn't right why was she just holding it "I can't huert this kid he's just a baby ." she thought "but still he is the key to our freedom." she yelled in her mind "but if we hurt him then we'll be like the bad guys that we kick buts." she then took him home with her she made shier that no one saw her with him. when inside undyne took her armer off she then grabbed her phone and called alphyes "h-hello?" alphy asked "hey can you please come to my house I need your help." undyne said "oh-ok I'll be their in just a sec." alphy said. a few minutes later a knuck at the door undyne opened it and saw alphyes standen their "hey-um undyne what do you n-need help with?" she asked then undyen showed her the baby "oh my god is that a human baby?" alphy asked "yea and I need you to help me take care of him. I know what your thinking why didn't I take his soul? well I just talked my self in to keeping him." undyne said "oh my s-so how are we going to keep him from asgore?" alphy asked then the baby started crying again "hey can you watch him? I'll get some baby stuff." undyne said then she left. five minutes later undyne walked though the door when she looked up papyrus was holding the baby "ooh look at you your shouch a cute little thing!" he said then he saw undyen by the door "aww undyen you should have told me you had a baby with you then I the great papyrus would have help you in taking care of him even though he's a human." alphy just stand there looking at undyen "I'm sorry he just came in and and" then undyen just put her hand on her shoulder "hey its OK a list he's the only one how knowns right?" undyen asked "nope I know as well but you know that I won't say a word about him." said sans who was sitting on the counter. after everything was setup for the baby papyrus asked what's the baby's name is "I'll name him frisk." she said. deep down she knew that this was a good idea.
