I know we had this conversation before, but it's hard to have a feel for the implied interactions which happen off screen. We should just be supplementing with head canon, but then when we meet someone we haven't met in a while it often plays out as if, well, we met someone we haven't met in a while (Anton and Regimand for example). And other relationships develop organically on screen, every frequent interaction informing Mathilde a little further. So I at least fail to make anything like a mental list of people she continues to have regular background contact with, except specifically Our employees and our girlfriend, Max, Johann, Egrimm and Panoramia (and formerly also the Duckling club and Belegar).
