its a small rural village with a population of 35 people maximum? just by law of averages, and rural settings, what are the chances of it having a gay couple?
and don't forget there was in its history, Zoe and Frankie, Zoe and charity, Zoe and...well many, Johny and Paul, Vanessa and Rhona for a bit of titillation....Finn and the HIV +ve nurse....
so for a small knit community Emmerdale hasn't done badly in showing gay relationships
