A "young farmer" who was an acquaintance of Oliver Charles was "enjoyed", along with his wife and mistress, by a member of the Slitheen family who had secretly killed him and used his skin as a disguise. (TV: Aliens of London)
Behind the scenes[]
The implication in Aliens of London of this Slitheen enjoying the young farmer was confirmed by Doctor Who: The Encyclopedia, which noted the disguised Slitheen had a number of sexual liaisons with the farmer as well as Charles' mistress and wife.
