Allergic to water. That wasn't what Mara had expected to hear, but then again she hadn't been certain what to expect to begin with. When Galen explained he'd promised not to tell anyone, she nodded. "I understand." She wouldn't pry, it wasn't her business. She also respected people's privacy. Of course, had this been a topic where someone's safety would be compromised by what Galen wanted to know, she would pry. But in this case? It was for protection not injury, so she went with no questions asked.
"It should feasible to make it so that water cannot get through. We can try it out and see. It shouldn't be that hard, in theory." Oh Mara was all ready thinking about how to go about this. She'd never tried it with water before, but that didn't mean it couldn't be done. Unconventional, yes, but she didn't think she'd be lectured on teaching Galen how to use a Protection Bubble to protect someone from water in this place.
