Well, the dvd is out and we finally get to watch the scene! Shad has posted a clip on YouTube:
At first I was a little disappointed. Initially it looked to me like the actors were adlibbing lines -- treating our precious book as nothing more than a prop. But NO! The two parents read an actual panel from page 55 AND, to smother icing on an already towering cake, the way the panel is read provides the only humor in an albeit intentionally humorless show.
We should note that the scene was shot in a mirror, hence the horizontal flip of the cover. Something to do with metaphors.
Will Bone Sharps continue to be featured in every episode of "Tell Me You Love Me?" Probably. We'll just have to watch closely and find out.
In episode 4, at 0:12, the dad (Dave) implies that he has read Bone Sharps to his son one hundred times.
