Ich habe mal bisschen gestöbert und folgendes dazu gefunden:

The name of this episode has multiple meaning, which include something like ?The Lives of Death? or ?Death?s Lives,? or perhaps ?Death?s Ways of Life.? In addition to the ?life-related? meanings, there is also an alternate meaning to ?vitas? which means to ?avoid or evade,? which would give the title the meaning ??To Avoid/Shun/Evade Death.? All of the possible meanings seem more or less relevant, making this the best-titled Farscape episodes to date, in my opinion. Puns are cool.

Das Problem dabei ist, dass Vitas eben nicht Nominativ Plural ist.. aber damit könnte man sich schon abfinden. :unsure:
