"get away" blog post 48

respond to the following quote from the chapter...what does it mean to you?
Tally thought of he lesions on shay's brain, the tiny concers or wounds or whatever they are that she didn't even know she had. they were in there somewhere changing her friend's thoughts, warping her feelings, gnawing at the roots of who she was?

To me it means that shay really isnt shay right now and tally cares about that. it also means tally would do anything to save shay.
