Skinny Pete has been ripped off by a drug-addicted couple and Walt has made it plain to Jesse that unless he does something about it, word will get around pretty quickly that Jesse and his crew are an easy mark. Jesse isn't a very effective enforcer, however, and soon finds himself in over his head. Walt goes back to work but not all is going smoothly. Walt's story starts to unravel when Skyler gets a call from Gretchen Schwartz and Skyler thanks her for paying for Walt's treatment. Gretchen doesn't reveal the truth, but Walt's bitterness at their past relationship—personal and business—comes out.
