I like the Inquisitor episode. Yeah sure it can be viewed as a ultra hammy , well dressed powerful evil alien episode initially. But one thing JMS does in B5 is reminding that he is not just writing for audience he is also writing and exploring the character , events and structure of B5 universe within the story itself. For us sci-fi veterans this is cliched overacted god-like alien episode maybe. ( I remember some drew parallels between Sebastian and Q ) But these characters have doubts , weak points , unexplored depths and limits. Inquisitor reminds us that these characters are right person for the coming crisis and decent for the moment. It should have been cleared from Vorlon's and and other characters point of view. Sheridan and Delenn are taking serious responsibilities.
