Background
Logan V. Simpson (The V is for Valerie) is the biological twin to Homer Simpson. He is the son of Abraham Simpson and a woman named Gwen Wendawire. He meets Homer Simpson and his family unannounced and stays with them because everyone except Homer likes him. Homer doesn't like him because of his mustache. Homer fights Logan to see who's the better twin, and Logan kicks Homer off a cliff, for now. Then Homer comes back and wacks Logan with a baseball bat in the head, killing Logan.
