I need some help. Back in the summer I was reading a WIP about rodney being transferred in to the body of a young genii girl after the genii lured the team to an ancient machine on another planet. Rodney's body dies and the team finds out what happened. Rodney resumes his dutires and Caldwell has problems with Rodney's transformation. Rodney and John get together. Any thoughts?
