If you are as impatient as I, the TV Guide website has a preview of tonights ep. It's a one minute clip featuring Lee. If you saw the promo and you know what the story will be focusing on tonight, I don't think there is anything particularly spoilery. It can be found here - scroll down to the bottom of the page.
In non BSG news, Bruce Campbell is doing a book signing/film presentation here tomorrow. It should be fun. I only wish we had more details about the schedule. At this point, we're showing up before 6 and hoping for the best.
