Annie's daughter

Ok, she a lesbian, this comes out at the beginning, and it only comes up twice more, both times in the context of a joke (when the girls are at the bar, and at the end , when her father tells her he can't take any more surprises).

Should they have gone into more depth with the topic? Or perhaps not put it in? (I liked the joke at the end but the scene at the bar was dumb)

I'm quite a lovely person - apart from my terrible taste in pie.
