So... in "Army of Ghosts" Torchwood has hundreds of personnel and a dozen locations around the UK.
Nothing in "Army of Ghosts" establishes Torchwood to have a dozen locations around the United Kingdom.
"Everything Changes," "Cyberwoman," "Golden Age," and "Fragments" all fairly well establish that the Torchwood Institute has had five branches that we know of:
* Torchwood One, based out of Canary Wharf. Torchwood One was essentially destroyed and most of its personnel killed or converted by the Cybermen. The
Torchwood website establishes that only 27 of its 823 staff survived the battle with the Cybermen, and that in the wake of the Cybermen attack, the Queen herself ordered Torchwood One shut down and disbanded.
* Torchwood Two operated out of Glasgow, Scotland. The file seen on Lois's computer in
Children of Earth seems to establish that Torchwood Two disbanded some time prior to the 456 Incident.
* Torchwood Three, based out of the Hub beneath Roald Dahl Plass. Torchwood Three seems to have been disbanded upon the resolution of the 456 Incident and the deaths of most of its personnel.
* Torchwood Four, location unknown. Captain Jack said in "Everything Changes" that Torchwood Four is missing, but we'll find it some day. (Might be the door the series needs to return after
Children of Earth, that.) Given that Torchwood One was in England, Two in Scotland, and Three in Wales, I would infer that Torchwood Four was located in Belfast, Northern Ireland (or, before the Irish Republic, in Dublin), but that's pure guesswork on my part.
* Torchwood India, based out of New Delhi. The radio play "Golden Age" establishes that Captain Jack shut Torchwood India down in 1924 because he knew the Raj was coming to a close and convinced the folks back home to bring the alien technology Torchwood India had acquired to Britain.
Torchwood Three seems to have been the only Torchwood branch still active during the 456 Incident (though of course one might choose to disregard barely-legible computer readouts saying that Torchwood Two had disbanded).
Whether or not the Torchwood Institute still exists,
de jure or
de facto, we do not know.
If all those people are dead... where is the money coming from? Where does Jack get his political influence? What politician is sponsoring this five man team?
DW established that the Torchwood Institute was established by Queen Victoria in 1879 and operated out of a royal charter. Presumably, then, the Torchwood Institute answers to and is kept funded by the Monarch (presumably taking orders from the Prime Minister when the Queen so orders, which she no doubt would in the majority of cases).
A computer screen in CoE said this: In the Torchwood Charter of Dec 31st 1879, "Torchwood is also to administer to the Government thereof in our name, and generally to act in our name and on our behalf, subject to such orders and regulations as Torchwood shall, from time to time, receive from us through one of our Principal Secretaries of state." So apparently Torchwood is supposed to be autonomous but receptive to orders it gets from the Prime Minister.
"The Runaway Bride" also established that Torchwood operated front companies; presumably it derived funds from those as well as from Her Majesty's Treasury.
It's even weirder because the police are aware of TW's existence in the TW pilot and in other episodes. Is this from the old days of actually having people or from the 5 man team?
Presumably the Torchwood Institute's existence is something of a poorly-kept secret, even if its actual mission is well-kept. Sorta like how everyone knew MI6 existed for years before the government finally admitted it.
Also, what is the nature of the relationship between TW and UNIT?
What about it?
The Torchwood Institute is apparently an organization operating on a royal charter. UNIT, on the other hand, is a United Nations military organization that divides its units (no pun intended) amongst UN Member States, with officers from each Member State's militaries serving on detached assignments but still answering to the Member State's own chain of command. In other words, UNIT is more of a coordinating body most of the time than an out-and-out sovereign military force (which is why the UNIT General took orders from the Prime Minister in "The Christmas Invasion"). Presumably the UNIT officers operating the
Valiant were the exception to that rule.
Who gets jurisdiction with what situation?
Presumably whoever learns about it first and doesn't call in the other for back-up. I doubt that there's any particular treaty outlining how responsibilities get divvied up.
Because if UNIT has these armies of soldiers running around England with their big SHIELD Helicarrier in the sky... what is the point of five dudes running around as Torchwood?
I dunno. What's the point of the having U.S. Marshals when you have the FBI? Organizations exist and they don't just give up their existence when another organization comes along.
