Don't kill her we could use her as a Rainman 

She could snap an be our resident weirdo NPC who if you sit with her might give you odd clues on the use of the stones...in fact that could be her stick; She could babble the operators manual for these things.

I see her sitting in a room of our safe house rocking and quietly talking as Season 6 of Spongebob and only the 6th plays on a constant loop

Maybe add the Fullmetal Alchemist deal about messing with life being how she got where she is or they didn't know when they caught her and subjected her to the experiment she was just becoming preggers and the process melded her with her unborn child .....stop me before I crash! lol
