"The Hemptress" is back — and this time, she's bringing a friend. Weeds returns to Showtime tonight to start its fifth season, and the network is using that opportunity to launch a high-profile and intriguing new series, Nurse Jackie.

I'm especially curious to see what this season of Weeds will hold considering the total transformation the show undertook last year. (Yes, this would be your cue to stop reading if you haven't seen season four.) The show officially shed Nancy's roots as a small-time suburban dealer, moving the show to the Mexican border and plunging Nancy into a relationship with a powerful Mexican mayor-slash-drug lord. Now, Nancy's told Esteban she's pregnant with his child; when season five starts, that baby seems to be the only thing keeping her family out of serious danger.

Following Weeds, we'll get our first look at Nurse Jackie, one of the more interesting new series to come along in a while. The show stars Edie Falco as a nurse with a drug habit and a very particular sense of justice (for example, the first episode involves a scene where she flushes a patient's ear down the toilet). Jackie's attitude is probably best summed up by her mantra — "Make me good, God, but not yet" — and the episodes I've seen are both smart and darkly funny.

Will you be tuning into either show tonight? To watch some behind-the-scenes clips of both shows, just read more.
