Statistical Probabilities, DS9 6
And this is Trek at full warp power.
Julian Bashir is handed the gang from Cuckoo’s Nest – genetically enhanced individuals who have cracked and become, as they say it, Mutants.
This is a perfect episode because it does three wonderful things. It works on all the socially conscious, symbolic levels Gene Roddenberry fans like. It propels the ongoing Dominion War plot. And it has solid a fanwank factor by bringing up the Eugenics War. Awesome.
