Shes nuts and is a great example as how BL deliver humour in the writing of the game.
On her diaries scatterred around Pandora you get some great lines like one I just heard
Day 617: Today is my birthday and I feel so lonely... one of the convicts got close today, I left him come closer... before I shot him in the chest... I immediately regreted it, a little company would be nice, even if a little awkward... I decided his name was Leslie and as a child all other kids would make fun of him for having a girl's name, that's what took him into the criminal life!
There are many, many more... as I get some I 'll post them here!!
I love once you have all of her Echos collected and you can listen to them in chronological order - you can hear her getting nuttier with each entry - I guess nearly 2 1/2 Earth years alone in an alien dig site will do that to you ;D
Later in the game you will come across her locked in a jail cell - make sure you take a minute to read the stuff she's written on the walls - priceless :-X
