What happened to Darlene and David?
The show establishes that Darlene and David have two kids together, but details are scarce about anything else. How long were they married? When and why did they get divorced? Where does David live?
Actor Johnny Galecki is obviously a bit busy on a little CBS show called The Big Bang Theory, so he can't be there for the entire revival, but he will appear on one episode, so hopefully that will clear some things up about Darlene and David.
