Actually, the song was "Simple Gifts," a Shaker song written and composed in 1848 by Elder Joseph Brackett. Aaron Copeland used it in his composition Appalachian Spring, which is how most people came to know it.
Actually, I didn't feel it WAS a fake out in that it's not unusual for guys who act like he does at the beginning of the episode to still feel terrible when it is revealed to them what impact this behavior has on their families. Some people are just like that, unfortunately. Of course, this episode was BUILT on fake-outs and at first I was a little offended as my first guess was PRECISELY the person who was, in the end, guilty. But after a few minutes, I realized that that had only been my first choice. That choice had changed twice during the episode--which is precisely what this kind of drama is supposed to do. I changed my mind about the whole episode. And you're spot on, IMO, about her acting. But then this series calls for more complex acting than most in its genre precisely because of the nuance on which Cal's work depends. :)
