“Una Salus Victus” is episode seven of season two of Andromeda.
The Andromeda Ascendant is escorting some unarmed medical relief ships to a planet that has had a serious disease outbreak that threatens 95% of the population with death. The closest route is blocked by a former High Guard outpost now controlled by the Drago-Kazov Nietzschean pride, which has enough firepower to blow all the ships away.
Tyr and Dylan go to the planet to disable the outpost. Beka ends up tangling with some other Nietzschean ships, and Harper ends up in command of the Andromeda. Not a position he’s emotionally suited for.
Dylan finally learns why the Drago-Kazov have got such a huge hate on for Tyr. He’s not immensely pleased with Tyr himself.
