Synopsis: "During a crisis involving the replicators, the station's crew is afflicted with an airborne virus causing aphasia. Everyone talks nonsense until Bashir realizes that the virus was engineered by a Bajoran terrorist attempting to sabotage the formerly Cardassian station, and tracks down the people who can create an antidote."
again, pretty average, just had a look through a trek site's episode guide n it looks like I've gotta wait a while to get to the good stuff
