Side question but how do hot female spies convince themselves to sleep with aged billionaires (or bug eyed government high ups for that matter), what is in it for them?

Are you that naive? Since chimps females have been genetically programmed to seek the Alpha of the species. Jensen is smart, resourceful, made a fortune, he's actually a great dude, he'd be a catch for most Chinese women. Aged or not, he can still exert influence, father offspring that will be generously looked after. He has many stories that would thrill most younger women, especially with traditional family values like the Chinese.

Everything to gain and nothing to lose.

What’s the easiest way for a woman to get into 10 Downing Street?

Suck Boris’ Johnson.
