I would like to say I know from a scientific standpoint, but I don't. all I know is, someone will walk into her cube and she will be sitting there, completely unresponsive. the rescue squad on base has to be called, they take here away (probably so the alien implant memory can be downloaded) and she shows up for work the next day, no prob.
someone told me it was a form of diabetes but I don't know that for sure. I don't talk to her much because she is very unpleasant; because she's so short, she has one of those napoleonic complexes.
