Beverage, Reminder, Touch
Beverage :: What do they most like to drink, and why?
Coffee. It isn't something they have in Dunwall but it's the perfect bitter flavor for Daud. Easily one of his favorite things about this brave new modern city.
Reminder :: How are they at remembering daily needs? What falls through the cracks?
Remembering to eat is difficult for him, especially if there's something important occupying his attention. This is the kind of stuff he'd usually rely on Billie or Thomas to bring up, but in the Hive there ain't nobody. Also, that whole personal grooming thing? Not a priority.
Touch :: How do they handle contact? Is their personal bubble big?
Daud's personal bubble is HUGE. He does not like to be touched ever at all, and doing so normally results in a bit of wrist-grabbing and glaring. If you touch him on the bare skin, though, he'll get really quiet and sort of embarrassed for a second, and then he'll tell you to get the fuck out.
