Mentally Challenged is an odd one. My Rosita is not mentally challenged, but my Julie Wilson was guaranteed to get it even though I save scummed her to try and avoid it. I'm nearly positive that Arizona did not have it the last time I got her, but I haven't gotten that far in my current game. Pacifist I think is just purely random. I had Aaron get it once which I found amusing. A pacifist berserker? Um, ok...Damn, code for adding random traits is really weird. Arizona and Rosita, two healthy women became mentally challenged, Ohio Adler - famous minigun weilding bounty hunter is pacifist
