In light of having just watched "Infection" again and knowing the discussion between Sheridan and Lorien in "Whatever Happened To Mr. Garibaldi?", I find the connection between the two episodes to be interesting. Lorien told Sheridan it was easy to find something worth dying for and asked him if he had anything worth living for. In "Infection," Garibaldi very near exactly makes the same comment to Sinclair. I know "Infection" was the first episode (not counting "The Gathering") filmed, so at that point I assume jms was still thinking that Sinclair would be in the entire five seasons. So, was Garibaldi's comment a reflection on jms having planned at that point in the show's production to have Sinclair be the person who went to Z'ha'dum and find Lorien?
