Re-watching the series, I am noticing things I’ve never noticed before. In disco Inferno, S2E2, at the end, with Sam and Al in the kitchen by the refrigerator, Sam asked Al if he has a dog. Al gives Sam a very strange look, and I was really curious what people think that look meant. I’m also curious, does anyone know, if Bellasario had worked out the entire storyline of Sam’s and Al’s backgrounds by that point in the show’s production? Did he know, for example, that Sam was married? Is that what Al’s look implied (that Sam had no dog; but he had a wife). I would be interested in anyone’s thoughts.
