Were Queenie and Tizzy married ? (Spoilers)
I wondered, because when we first see them he seems to just be courting her but then he spends the night and then seems to be living there and then she announces that she is pregnant but continues to refer to him as "Mr.", which I know can be a Southern affectation, but it seems unlikely that their relationship could have been "unofficial" in those days, especially living in a house full of white senior citizens.
"I say ! Open this door at once! We're British !"
