Curate, connect, and discover
Obviously Donella and Cyrus are the two main people Hugo worked with, basically being his family, but I feel like some other soldiers would be pretty good friends with Hugo and they alongside sometimes Cyrus (though he's got a bit more of an important job than regular soldiers) would teach Hugo things Donella couldn't if she was to busy, like how to cook or sew
Not saying Donella wouldn't do this, but I can imagine her being at least a little neglectful of Hugo, and some soldiers might take pity on him
