When I first read the title, I was hoping it'd be all about Jack's character and his history, like they did with Kevin's in the last season. I am so glad it was. All of the pieces put together, very realistically showing every detail... the effect of a husband's alcoholism on the wife (specially the mailman scene), how the husband used to be a non-alcoholic... successfully leaving the audience curious as to why he started.... It's all just very realistic but very hypnotising at the same time.
