How would Maggie's storyline have been different if Adele was still alive? I think Adele would have really added to the story. Assuming she hadn't had altzeimers, I think she would have had a lot of input. Just as she thought that she could move on from Ellis, Maggie turns up and serves as a reminder.

I think eventually she would have been there for Maggie and even encouraged a relationship between her and Richard.  I could also imagine her getting on well with Maggie's mother.
