yandere Duncan x Courtney

hello this is my first total drama fanfic. I did put a poll on the total drama amino that I'm in and more people wanted to see yandere Trent x Gwen but I'm doing this idea anyway because I really wanted to do this. anyway now thats out of the way. it is total drama all stars and Duncan gets really jealous about the fact that Courtney is dating Scott. he gets really mad to the point where he wants kill Scott and anyone that even bothered to flirt with her.
