people are good 70% or so water content, so logically she should be essentially incapable of physical contact with others... Ditto pretty much every living thing on this planet really, at varying percentiles, what with
life as we know it relying very heavily on water as fundamental metabolic solvent.
It'd be one thing if it was just her skin being
hydrophobic - that'd just be an odd quirk of no very great consequence. But what is, at the current writeup we were given, essentially a forcefield you can't switch off that repels an element absolutely vital to carbon-based life and ubiquitous in all but the most savagely extreme and inhospitable environments?
Really not confident this idea was given the necessary amount of thought.
