My GF and I have been sick with colds this week, so we binged both seasons in about 3 or 4 days. We were also bothered by the drone pilot subplot. When the couple gave their names as Stanley Kowalski and Blanche DuBois, I thought for sure they were spies trying to get secrets from him. But the whole thing just went nowhere.
In addition to the Annandale, MD, and non-existent hospital near Nats Park, I also noticed that on Jack's first date with Cathy, those were dungeness crabs, not Maryland blue crabs, and it was a pretty fancy-looking place for a crab house.
Then in S2, Cathy completed disappeared so he could sleep with Harriett the spy.
