Here is where the man who puts the boffo in 'boffin' usually lurks when not actively needed for some new disaster of the 00s' making. Normally (four-dimensionally) inactive, this particular location can, in a jiffy, deploy defences which make it the most violently secure place in the building, assuming you're on the guest list.
Qs then and now[]
The current Q[]
After 007 mocks the Quartermaster for his youthful appearance, the squint hazards that he "can do more damage on his laptop in his pyjamas than 007 can do in a year in the field." Commenting on 007's usefulness to MI6 he admits that "every now and again a trigger needs to be pulled." 007 quips, "Or not pulled. It's hard to know which in your pyjamas." The two formally acknowledge one another and exchange a friendly handshake, a mutual respect between the pair forming.
He then hands 007 his new field equipment: a biometrically-encoded Walther PPK (coded to Bond's palm-prints) and a radio transmitter for tracing Bond's whereabouts in the field. 007 is rather underwhelmed by his new equipment, causing Q to retort "Were you expecting an exploding pen? We don't really go in for those anymore."
