Tonight's pre-credit sequence flashed back to a young househunting Walt and Skyler looking at the house they'd soon buy. The season's recurring theme of Walt as a man of caution is turned on its head, with Walt scoffing at the three bedroom house as too small. When Skyler suggests it's as high as they can go in their price range, he asks her, "Why be cautious?"

Throughout the freshman season of "Glee," I've harped upon the show's failure to embrace its comic superiority and abandon the angst-ridden, surface-level drama that dominates the show. For about 15 minutes each week, the show is the best comedy on TV. The rest of the time it's one of the worst dramas.

In last week's episode of "Breaking Bad," there was a curious moment just before Walt got his dinner invitation from Gus. As Jesse was about to open a valve that would release toxic fumes into the lab, Walt had to remind him to put on his mask.
