Eleventh Hour: Containment

Professor Hood (Patrick Stewart), a Science Advisor for the Home Office and his bodyguard Rachel (Ashley Jensen) are called in to help out on an outbreak of a mysterious virus that has killed one man and likely affected up to 21 more people. Dr. Martin Callan (Nicholas Anderson) is a virologist in charge of a team of scientists brought in to contain the virus and to track down it's source.
Through investigation and interviews, the virus, which is now known to be a hybrid form of small pox and tanner pox, is tracked back to a worker at a refrigerated warehouse. The workers at this warehouse are predominantly Chinese immigrants, all of whom are sick. They are all put into quarantine, as is Rachel because she came into contact with the blood of one of the men.
Hood along with the help of a young virologist discovers that the workers do not have the hybrid virus but only chicken pox. When Hood, Rachel and one of the workers go back to the warehouse to look for containers of Variola (Latin for small pox), they find the samples missing and that the warehouse owner has taken them to sell to Callan, as they were samples from his lab when he used to teach at the University. The man end up taking Rachel hostage, but fortunately for her, Hood will not stop until she's safe.

Well, no Gepetto, so I guess that question is answered.
This episode was about containing a virus, so I expected something a little more like the CDC and it's EIS agents, but instead got Callan and his group of academics. I have no idea what the situation is really like in Britain, but Hood says at one point "the United States spent a billion dollars on this, we created 37 committees", or something very close to that.
Twice in the episode, Hood explains scientific theories to lay persons, and I think that is pretty damn cool. I don't know if anyone came out of watching this show telling their friends that they now knew more about quantum mechanics or about how small pox was spread, but it is very cool that Hood was explaining this a person as a teacher, and that this wasn't something just said as part of the exposition to fill in the gaps in story.
This show could have gone the CSI route with lots of special effects scenes and one expert talking to another expert, but instead the show has more of a police procedural feel to it. Oh, and the opening sequence was all very X-Files again. I like that. We start off with this crazy looking scene and then explain it all using science.
I don't know how the British Intelligence and Security services are set up more than that MI-5 is domestic intelligence and MI-6 is foreign intelligence, but they are both structured like the CIA. Special Branch, I thought was another name for MI-5, as was Home Office. But Special Branch might be the domestic Special Forces that MI-5 uses for muscle or as a SWAT team.
