Re: Gwen S/Peter P
There was no need to emphasize her sexuality. My point is that you're basically programmed to spend the rest of your life with her. I have a purpose in your life and, once it's been served, I'm extraneous.
Regarding the appendages, it's possible you created them to serve a purpose, and that exposure to something like radiation, while wearing them, could have caused a mutation that allowed you to control them.
