Genji took the water but he didn't drink it straight away, just flexing his fingers around the glass with a slight frown on his face. Perhaps he shouldn't have lead the conversation up with the mention of attacks, but it was probably worth warning her - he respected Angela greatly and he didn't necessarily want to lie by ommission and not talk about them, but- well. She probably could have done with some more time to adjust first, perhaps.
"Well- attacks perhaps isn't the right term. It seems that a lot of odd things happen here," he raised an eyebrow. "Odder than in Overwatch, even. Not just Omnics versus people, but- large birds attacks, er-," he waved a hand. "Other things. I did some reading back on the device and there was talk of people vanishing temporarily to another world, for example. Or going back in time," he hadn't really known what to think of that then and he still didn't now. Perhaps Angela would morph into an actual angel and confirm his suspicions that this was all some kind of fever dream.
