Plot-wise, "Casey Casden" has nothing new, with plots borrowed entirely from the original. However, they do come from separate episodes, and we get a good idea of what the writers are trying to do. Instead of create their own show, the writers are trying to stretch out seven episodes worth of material over 12 episodes, inserting new but not essential elements--in the case of last week's episode--or simply leaving things temporarily unresolved--the wedding and Karen's thing.
"Casey Casden" gets a bit too silly with the baby plot looking like a Leverage episode, but the episode does get to the heart of the problem with the family, with Fiona calling into question whether the kids are getting hurt. Seeing how crazy Debbie is, I can't say the family is doing too great, although we don't know what more Fiona could have done.
Score: 8.8/10
