Victoria Sweeney is the head of security for the lycanthropic corporation known as Segolia. When referred to by her underlings and others in the firm, they call her "The Sweeney". But always behind her back.....
For the British viewers, it would seem that the nickname is a reference to the TV show from the 1970s which starred John Thaw and Dennis Waterman and which inspired the ambience of Sam Tyler's nightmare world in 'Life On Mars'. The rough tactics of the members of that team of detectives would suggest that those Segolia employees saw a kinship in Ms. Sweeney to those maverick coppers.
But "The Sweeney" is actually a reference to an actual squad of detectives.
The Flying Squad is a branch of the Specialist Crime & Operations section, within London's Metropolitan Police Service. The Squad's purpose is to investigate commercial armed robberies, along with the prevention and investigation of other serious armed crime. Possibly one of the best known operations of the squad was their foiling of the Millennium Dome raid.
'The Sweeney' is a 1970s British television police drama focusing on two members of the Flying Squad, a branch of the Metropolitan Police specialising in tackling armed robbery and violent crime in London. The programme's title derives from Sweeney Todd, which is Cockney rhyming slang for "Flying Squad".
A further film adaptation, The Sweeney (starring Ray Winstone), was released in 2012.
So there is no discrepancy in calling Victoria Sweeney "The Sweeney". But you might be in for worse than a Zonk should she catch you doing so!
