Really? I read it as the nuke was going to go off during Tuesday's episode.
C'mon, you had to know five minutes into it that it was going to end with a detonation!
Sometime during the middle of episode 4 I was figuring out times and I got the hunch a bomb might go off. But I didn't think that from the get-go. It seemed like the father story was underdeveloped, so I thought he'd be around a little while longer.
