Synopsis: In which a war criminal long thought dead arrives on the station with a tantalizing offer of an immortality serum. The League of Unaligned Worlds wants her tried for her crimes, but the other civilizations trip over themselves racing to prove who can be the most ethically compromised. Then the Vorlons just unilaterally blow her up, so never mind.
