The Carters' backstory is really all about Shirley and Mick. We know very little about Tina's past and Linda's past in comparison to Mick and Shirley. After we find out all the secrets about the Carters, the focus should be shifted to Linda and Tina. So here's an idea:
Linda's mum, Elaine, should be brought into the show. I think she should be joined by a big sister, Sheryl, a bit like a Rainie figure, though not quite. Sheryl left home at 16 and refused to go to John's funeral. Linda and Elaine rarely talk about her and haven't seen her in years. However, Linda never forgave Sheryl but she was unaware of the truth. John, her dad, abused Sheryl when she was young and when Sheryl told her mum, Elaine, she refused to believe her and sent her away. Sheryl did return to Canning Town but burned down the pub to kill her father. Linda finds out about her mother's deception but someone finds out that Sheryl killed John and how far will she go to keep her secret safe?
For Tina, obviously there should be a domestic violence storyline with Tosh but I'd like to know more about her sexuality and how she brought up Zsa Zsa. Therefore, Zsa Zsa should return and perhaps Zsa Zsa's stepdad, Andy, should make an appearance too. That way we could learn the truth behind Tina's sexuality and why she couldn't bring up Zsa Zsa.
