I think that we'll here more about Eugene's dad and Mandy's parents.
With Eugene's dad, there still seems to be a lot of mystery and intrigue so I expect some thrillers surrounding that.
I'm not eager to have Eugene and Katrina having a child yet because we need to focus on his dad right now. Also, Katrina's hardly been around (not that I mind since I don't like her voice) so it might be kinda rough to suddenly unearth her again only to have a major change.
Mandy's family situation should also resurface at some point but I don't know how soon. They might take their time on this one.
We'll probably hear more from Grady and family. AIO seems to want to make him an integral part of the show to explore the ideas of a non-believer reacting to (and interacting with) religion but remaining skeptical. At the same time, they're exploring the single parent family with younger children. We've had Connie, Whit's grandkids, and the Myers, but those situations were all different.
There'll undoubtedly be more shows with the Washingtons. They're are AIO's "first family" right now and we hear plenty of them.
