*Moya is in need of a filter that will allow her to comfortably travel in Tormented Space. But before the mechanic will board, a doctor must certify the passengers are free of space madness. While waiting for their exainations, Moya's crew dines on mollusks brought by Dr. Tumii, and they contract fatal food poisoning. Only the doctor can cure them, and he demands a ransom to do so. When Crichton, Aeryn and D'Argo visit Dr. Tumii, he only has one puprple mollusk - so he can only cure D'Argo and Noranti. *Source: Back of card
