Trivia: J. Michael Staczynski wanted to create mature, adult science fiction not a kids' show. His rule was that any cute kids that appeared in an episode had to be killed off by the end of that episode (e.g. "Believers" and "Confessions and Lamentations.").
Trivia: Straczynski planned out Babylon 5's entire story arc from the beginning. He kept a written copy of it on a 200-page encrypted computer file. Straczynski never revealed his full plans to his writing team until the very end of the series. He intentionally included red herrings in the plot so that viewers would not be able to predict the outcome of the series.
Trivia: Jerry Doyle says that his favorite episode was this one because his character spent the entire episode in a coma - but Doyle received full salary for the role anyway.
