     Uncontrollable, Incorporeal Phasing does seem like a good idea - it really helps to intensify her fears of absolute helplessness (perhaps even being mute all the while as well, since she no longer has lungs or vocal cords as a 'ghost'?); an alternate idea might be the ability for her to fast-forward through small 'blinks' (phasing into an incorporeal, with the world slowing down around her during it) of time while in this uncontrollable state - perhaps making her feel even more helpless and angry while feeding slightly into her love of clockwork mechanisms and their ability to register it (the sense of time, that is)?
