As for the neighbours on the other side, for a long time it was ambiguous if the visitor with Pizza and Larger was a young man or woman. I think Jan used to play it as male and I enjoyed that ambiguity, reading it as a woman taking on male posturing. In trainers and trackies, hoodie up and cap on there is an effort at de-sexualisation akin to the job the niqab is designed for with the neighbour who she abuses for being so alien. In the process you are describing, negotiating Alex taking over Jan’s role there was discussion around this area and it was agreed to give a slightly stronger clue that this is supposed to be a female figure and now her hair is seen beneath the hoodie.

And so on….
