I'm pretty sure this has been discussed before, but I've been trying to think of different ways it could be done narratively. If you are absolutely 100% gun-to-your-head getting 2hufied, which method do you think you'd prefer?
-Twinning - You and the original 'hu are both active at the same time
-Overwrite - You take the place of the original 2hu, but remain fully yourself mentally.
-Memory Loss - You become the 2hu physically and mentally, leaving behind the person you were.
-Combine - You and the 2hu fuse completely, combining memories and personalities into what is effectively a different, new individual
-Reincarnation - Take the place of the 2hu the instant she's born, and live out her entire life from the beginning
