Here's something I didn't know: season 1's order is only 12 episodes. Don't know if they'll get a back nine for the rest of the season or if 12 episodes is it. Also, don't know how many episodes next season will be. If it's just 12, they're following the cable formula now for dramatic series.
Here's the thing: Like Super Shane Spear said, Artie has seem to have a more aggresive attitude in the last month or so on the Stern show. The most noticeable bit for me was when he went off on Lisa G.
