I was impressed that the show managed to slowly clue people into Patsy being gay without hitting us over the head with it, even from the first episode I think people speculated that Patsy was gay.
As being gay goes in the 60's I think she's not so badly off. She's got her own career that pays decently and some women dedicate their lives to, avoiding getting married. Her failure to marry wouldn't be questioned too much. Plus it seems that her immediate family are dead so she won't have family pressures there. She's got a friend who seems accepting, understanding and supportive. Plus, she's working with people who may not like it but will probably be mostly tolerant. If the residents of Poplar found out that would be another kettle of fish,...I'm sure the vast majority would not want her as their midwife.
I don't think she will tell anyone but Trixie. The more people that know the more dangerous it is for her. Loved Trixie being inspired to stand up to the bigots at the Rose Queen, although I didn't really like her "love the sinner" comment but I don't think she really believes its a sin.
I though Delia seemed nice but I was seriously expecting someone less plain and more Trixie like but then again I'm all for shipping Patsy/Trixie. Yes, I know its madness. Also, half of me doesn't want Patsy to have a girlfriend as I think it might be interesting to see a little bit of a lesbian scene from the 60's.
