He's the husband of the polygamist's daughter on  'Big Love' and he's spent two seasons getting physically and emotionally battered about on 'Breaking Bad,' but as the AMC drama's third season continues (Sun., 10PM ET), 'Bad' Emmy nominee Aaron Paul may finally be growing a tougher shell.

Paul plays 'Breaking Bad's' Jesse, a middling pot dealer who gets swept up in the dark, dangerous (and sometimes darkly funny) world of major drug dealing when his cancer-stricken former high school chemistry teacher -- Bryan Cranston's Walt White -- pulls him into a plot to cook and sell major batches of drugs and secure his family's future.
