Great catch.
Yeah, there’s obviously some reason that they’re all agitated about getting recorded. They’re probably a group of spies getting together and showing another spy around. After Fang Fang and all her sleeping around with upper-level Cali pols, it’s a safe bet that the ladies here have done ‘extensive bed work’ in the UK. If they had just walked by, none of this would have ever been recorded.
More likely than not, they’re going to be called back to China and it should be interesting to see if they ever come back.
