Stories that just ended without follow-up

One of the stories that I'd love to see is Amelia's survival as a young mother with Dan in prison. That was the story that got me hooked on this show and was when I first began watching. I'm surprised that she hasn't been woven into the fabric of some of the other stories. I also enjoyed her friendship with Mandy at the salon.

Are there other stories that you saw end without follow-up, where you would like to see what happens with the characters (as opposed to being relieved that the story just ended)?
