translate English to French: Kirk and Spock then bring Jones to the station's bar, and give him a choice: twenty years in a rehabilitation colony for transporting a species proved harmful to human life, or pick up every tribble on the station (which Spock calculates would take 17.9 years). Jones accepts the latter.
A bord de l'Enterprise, Kirk trouve son propre vaisseau vide de tous tribbles, et demande à Spock, McCoy et Scotty comment ils ont fait.
