[FATBOY]

Think Harry is on dangerous ground going against the Home Secretary's wishes and then deceiving him. But what an interesting fix up to deceive the HS and the Russian ambassador - did Aziz come back to life to fake the killing of Viktor (so he's not dead as femaleBertieWooster suggests)? Was the scene filmed before Aziz was shot by Viktor or was an Aziz look-a-like used?

Think the HS has an inkling somthing is amiss, also Porton Down must realise sooner or later that they have the real sample (or do they?).
