Even though Showtime's Weeds doesn't lend itself to fun gimmicks like fountains bubbling with the blood of the freshly slaughtered, the series is doing what it can to lure in new subscribers with promotional stunts of its own, like casting a recently decoupled Olsen Twin as a fledgling drug-dealer who believes Jesus has sent her forth to get the world really, really high.

Though we had a chance to preview her work a few weeks ago, last night's episode gave us our first full dose of Mary-Kate's acting abilities, and we have to say we're pleasantly surprised: while some of her deliveries could be more emotive, she never once seemed to pause to get a line reading from her phantom twin, indicating that she's grown quite a bit in her craft since her days of churning out straight-to-video tween-nip.
