Jane: Thanks jeff... Now ben, where should I cut you first?

and no that is not her face. She just has scabs from where Jeff cut her along with stitches since they open up sometimes and thats it. Her face is just pale and cut up. The burnt skin was repaired just like Jeff, Leaving her with white skin.
