I thought more about it... In fact, my good-half would be so boring that if nobody kill her before, my bad-half would kill her! In fact, I think that few second after I was chopped in half, my good-half would be dead... and my bad-half very happy ^^
*Edit: I forgot: my good half would have absolutely no self-confidence, with a big complex of inferiority, and would probably even try to suicide before my bad half try to kill her... No, really, no future for my good half...
