Deep Geeking: "Z minus 7 Days". After the silliness dies down, Tim and Summer discuss "Shadow Dancing", the episode that culminates in Sheridan's and Delenn's goal to get all of the League Worlds to work together in mutual self-defense against the Shadows. The B-story deals with Franklin dealing with the consequences of his actions and his choices, by literally talking things over with himself. And Jeffrey adds his own perceptions on why the cast (and crew?) were starting to look shaggy and scruffy towards the end of Season 3.
