You mark my words, Skyler. Toe the line, or you will wind up just like Hank.
Skyler White: Walt. Tell me what happened. Where is Hank? Please. We need to know.

In the flashback scene before the title, Walt is speaking with Skyler over the phone after his first cook. She is still pregnant, but has the short hairstyle from later episodes rather than her long hair from the first couple seasons.
The opening credits do not begin until 18 minutes into this episode, after the first act is over.
