These few seconds were not broadcast because the director considered the scene "...too real". Following this episode, Vila becomes very wary of Avon's motives. Servalan was played by [[Jacqueline Pearce]] (in the B7 audio series, she is played by [[Daniela Nardini]]). She was the principal villain of the series. Her creator [[Terry Nation]] originally intended her to make a single appearance but she finally appeared in all four series, the only guest character to do so. She is principally concerned with organising efforts to destroy Blake and crush resistance to the Federation's rule. She is quickly revealed to be a cold, calculating, ruthless [[Psychopathy#Sociopathy|sociopath]] who is not above using her sex appeal and [[Superficial charm|charm]] to get what she wants. In the novel "Lucifer" by [[Paul Darrow]], set 20 years after the events of Gauda Prime, Avon and Servalan have their final confrontation: Servalan is killed by Avon's lover, Magda, before Avon escapes and recovers Orac. In Tony Attwood's non-canonical novel "Afterlife", she is shot dead by Korell, Avon's former jailor and his and Vila's crewmate - herself a would-be dictator. Servalan/Sleer appeared in both of the BBC's official audio adventures, "[[The Sevenfold Crown]]" and "[[The Syndeton Experiment]]". She also returned in the unofficial audio adventure "[[The Logic of Empire]]" and in subsequent Big Finish audio adventures. Slave is the flight computer on the "Scorpio". It is featured throughout the fourth season voiced by [[Peter Tuddenham]]. It was originally programmed to respond only to Dorian's voice print, but Orac was later able to remove this so the computer responded to anyone who addressed it. The crew made general use of Slave's abilities throughout their time aboard the ship. Slave was a unique system installed by Dorian, possibly making use of work by Ensor. It could communicate verbally with the crew and handle routine flight procedures at a level of sophistication unmatched by any human-built computer with the exception of Orac. Due to Dorian's rather strange sense of humour, Slave was programmed with an exaggeratedly obsequious and subservient personality, habitually addressing the crew as "Master" or "Mistress". Slave was quite capable of directing the "Scorpio" from planet to planet without human assistance, and it was in fact impossible to land the ship in its hangar on Xenon with the computer off-line.
