Let's review, shall we?
Your plot: Gerard from a few years before turns up. Frank finds him and then Gerard comes in. "Gee" gets together with Frank. Then "Gee" comes onto and has sex with Gerard, however in your story he rapes him. "Gee" is a result of a drug-addled mind.
Her plot: Gerard from a few years before turns up. Frank finds him and then Gerard comes in. "Gee" gets together with Frank. Then "Gee" comes onto and has sex with Gerard, however in her plot it is consensual. "Gee" fits nicely into her crack-fic series of weird happenings.
Some key quotes:
Her story: "Can we keep him?"
Your story: "Can we keep him?"
Her story: "We can call him Gee, and you can be Gerard."
Your story: "We can call him Gee, and you can be Gerard,"
