I thought she would end up a hermit, hell even turn to veterinary, she needed a break, it was telegraphed from the start but, it didnt need to be a psychotic one. Im guessing is for plots sake. Panacea will be esential on escaping the birdcage, giving everyone involved the physiological tweaks required for functioning in vacuum.I found that plot resolution really problematic, because it seemed to lend too much credence to the "bad blood" theory of evil. "I guess she was right all along, her father was a bad guy and she was doomed to be one too." Just a very uncomfortable message there.
