Okay the guide is still in production regarding the screengrabs and some of the details, which I will fill in as I rewatch the episodes. If you are a member of TV.com (and registering is free) you may click on the TV.com emblems to go to the episodes there in case you want to rate or review them, and see extra info not found on this guide. (I do maintain the guide at TV.com but that doesn't mean the two guides are identical.) There's a forum over there too.
