'Breaking Bad' preview: Have a Coke and a pile of money

Here, maybe, is the moment when Skyler White realizes just how big the business her husband has gotten into really is.

In this scene from Sunday's (Aug. 28) "Breaking Bad" episode, "Problem Dog," Walt (Bryan Cranston) brings a few cases of soda to Skyler (Anna Gunn) at the car wash, their front for laundering Walt's meth-making money. He also brings a couple weeks' worth of his earnings -- and that's where things get dicey.

In keeping with the season as a whole so far, there's a palpable amount of tension as Skyler gets a little more insight into how deeply Walt is involved in the drug game, and in turn how big a hole she's now in as well.

"Breaking Bad" airs at 10 p.m. ET Sunday on AMC. For more, follow the show on Facebook and Twitter.
