Chapter 61: Goat vs Fish

 You ran to Asriel to tell him to stop. As he heard your voice, he stopped attacking Undyne and said - Y/N get out!!! this guys are trying to- but in that moment Undyne, who was in some kind of...magic armor?...threw him a spear that as it hit Asriel's face, it broke into a million pieces. - Fuck!!!...- Undyne shouted. You asked Asriel - What are they trying to do?...- and then Asriel came back to the form he was a few seconds ago. - Y/N...I've got to tell you a lot of things...- Asriel said while grabbing you by your shoulders. - I'm not a murderer and I can prove it...- Asriel affirmed, as you heard that you, smiled and said - I knew it!!!...wait...then who killed Asgore?...- and Asriel replied - Undyne and...- and you asked - And?...- and Asriel answered - It doesn't matter...the point is that Asgore's back was full of magic powder...I did a magic DNA proof and it turned out to be Undyne's...- and you reacted "Impossible...so my suspects of Undyne being guilty were true?!...could it be that-" and Asriel interrupted your thoughts - Yes...she also killed Tom and incriminated Asgore of it...- and suddenly Undyne yelled - Asshole!!! you got no proof about it!!!...- and Asriel responded - You are wrong, Undyne. Here I have one sheet of paper written by Undyne, a testament written by Asgore and the photo of Tom's corpse that is supposed to be written by Asgore. Y/N, please compare them. - while putting the proof in front of you. You compared the letters and Undyne's were exactly the same as Tom's photo. Asriel was right... Undyne was a murderer... As Undyne saw you noticed the truth, she snapped. - ROAAAARRRR...I HATE EVERYONE...ESPECIALLY YOU...ASRRRIELLLL...YOU ARE GOING TO PAY!!!...- Undyne shouted while running at full speed to Asriel. She was about ten meters away from you and Asriel, but before the action could take place, Toriel, Papyrus and Sans stopped Undyne. - WHAT THE HECK IS WRONG WITH YOU?!?!?!...- Undyne said and Sans coldly responded - Undyne, u have been a very bad girl...- and Undyne replied - As if you were innocent...- and Papyrus responded - Stalking someone you care about...doesn't compare to kill for someone you care...- and as you heard that, you got in shock. You almost fell but Asriel grabbed you. - If what my son said is true...then it will no longer matter what happens to you...hehehe...- Toriel added. By watching how the situation was going on, Asriel decided to leave along with you. Once you left, Toriel, Papyrus and Sans made a feast with Undyne's corpse.
