This is a very well done promo for Emmerdale when it expanded to 5 days a week. As you can see, the show had a very disparate cast at this point (not even including new characters like Edna, or old characters oddly missing, like Kathy), but the promo does a good job of grouping based on families, couples, isolated characters, and Cain with the two groups he would wreak the most havoc on - the teens and the Reynolds family.
I have no idea who the little girl with Andy/Joseph/Robert/Donna is, and I’m not 100% on the two guys with Scott, but otherwise, I know everyone, which is...kind of sad, really.
The two sides of Sarah is incredibly striking, the most striking part of the promo. I pity viewers who tuned into the show for that sequence and saw her burn alive a month later.
