The Breaking Bad marathon, showing all episodes in sequence on weekends through the end of January, picks up today after yesterday’s inaugural launch. The action picks up at 2 p.m. ET, with the fourth episode of Season 2: “Down,” which focuses on Anna Gunn as Skyler, the increasingly dissatisfied wife of Bryan Cranston’s Walter White. The title, it turns out, is part of a clue about what this season is leading up to – but only a small part. Just go with it. The point is, series creator Vince Gilligan and company had much more of an idea where they wanted to go, season by season and in terms of the show’s overall arc, than the writers and producers of most TV series.
