I hope that whatever happens to her is fixed by mid season. I want Agents of Shield, not Avengers part two.
This show doesn't do "fixed". It does changes and repercussions. Any status quo we've ever had has been fairly short lived.
Ward won't be getting "fixed", neither will Mike, Fitz or Skye. They're permanently changed by their experiences and if something significant happens to Simmons (and I can't see how it wouldn't be significant) there's no going back to normal. Indeed, as I said earlier, she's already undergone a subtle but significant change in her outlook and sense of morality and it's safe to say there won't be a magical fix for that either.
Even with Coulson; the writing may have stopped but the Kree influence is still in his system and could rear it's head again in some form or another if given the proper stimuli.
Despite her abilities, Jiaying couldn't be fixed either. The mental scars of her experience ran too deep and it twisted her into a different person. I wouldn't even say Cal was "fixed" so much as he was remade almost from the ground up. No doubt the TAHITI protocol didn't reverse the "tinkering" he'd done to his biology, but without his serum and the motivation to use it, it's merely dormant.
