Star trek voyager 2 x 14 threshold Tom Paris is dying. What does the doctor do? He calls for a neural simulator. Thats right, a simulator, not a stimulator. From now on in the series, Tom Paris as a personality is a simulation within a dead body. Three simulations actually, they used the machine three times.
Threshold is the most awful episode ever though. Apparently, your DNA contains all the species your kind will ever evolve into, and evolution is a set path.
Did they just have transwarp half-fish half-other-fish children? Also, what the hell is up with all the sex and mating references in the second season?
