Kosmo, I had exactly the same thought. Will Charlie come back to Justin as a result? I can’t work out if I’d like to see him back, as an interesting character and plot disruptor, or not because I want Ian and Adam to stay together.
I think it would be nice to see Charlie return and (without disturbing Adam/Ian) get to understand his back story.
He was acting as if it remained awkward for a homosexual to declare his position at work. And yet back in 1990 I took a job where I was advised that one of my direct reports was openly gay. Not a problem for me and indeed a very reliable and conscientious employee. And everyone in the building knew.
So I never did quite understand Charlie’s problem in when 2014?
I saw it as more of a struggle for Charlie personally, coming to understand his own sexuality and his feelings. Also we don’t know about his family and other backstory (although a sister appeared at one point didn’t she?). All the more reason, as you say, for us to learn more about him!
I do sort of hope Miranda appears from time to time, she’s great – in her own way.
