Kryten is a Service Mechanoid and when first encountered by the crew, he was bound by his "behavioural protocols", but Lister gradually encouraged him to break his programming and think for himself.
Kryten je sanitacijski mehanoid i kada ga je posada prvi put srela, bio je ograničen svojim "protokolom o ponašanju", no Lister ga je postupno poticao da probije svoj program i misli na sebe.
