This freaks you out more than it should. You turn the flashlight back to blue and shine it on his lower body. Watching his skirt turn back into pants, his stockings to socks and his heels into shoes. You decide you should watch out with what you do with the flashlight, as it can have pretty awkward effects.
"I was wondering what we should do now," you say to Gene. "Well, I was thinking," he replies, "we could go back to my place and have a little fun?"
Fun? The only thing you can imagine him meaning by that is something you don't want to do with him. Is Gene still your boyfriend? Please no... "Well... what kind of fun," you ask. Gene puts his mouth near your ear and whispers: "the dirty kind."
Reality has changed in a way you did not expect. Has Gene always been interested in men? That could explain everything, though you don't understand why reality didn't change back. Maybe you have become gay? No, you know you are still very much attracted to women - you don't find Gene attractive in any way.
You realize that you don't change when reality changes. Maybe that's why it wasn't necessary to undo the fact that Gene is your boyfriend! How are you going to get yourself out of this, though?
