The time travellers take Vicki to ancient Rome and squat in someone’s villa for a month where Ian and Babs shag like rabbits before she acts like a slut around a married man and he goes off to sink ships and attack people with swords. If that wasn’t bad enough, Vicki wanders round the emperor’s palace trying to poison everyone and the Doctor impersonates an assassin while encouraging someone to commit arson.....and laughs about it!

Come back Susan...Please! Clearly you were the moral centre of the group because they’ve all turned into complete shits without you.
