Tom and You are enemies and you guys hate each other horribly to the point you can kill each other. You're friend is actually Bill who is his brother so everytime you visit you have to face Tom

You are at Bill's house and you're just in his room talking, playing games etc. until you see the door swing open and you see Tom and Tom glares at you Tom: "BILL WHAT THE HELL IS SHE DOING HERE AGAIN!?"
