Electricity has nothing to do with the body, unless your body is any parts mechanical - but I assume that is not the case with you. [ good thing he can fake patience! honestly it does not bother him much to deal with someone who might not understand this level of technology, mostly because cassian is tired of being the one in the dark on everything else. ]

[ when the man reaches for his caf, however, cassian tilts the cup inward and even takes a small step back. it's a very fluid dodge, barely calculated in the same way the attempt to grab the cup in the first place was. but at the same time, it's a movement that clearly says mine. ]

This level of technology is not unfamiliar to me. While it is not the same, it is not difficult to adjust to. [ he could try to explain transmissions, but the man doesn't even seem to get electricity...! one thing at a time. ]
