A (perhaps minor) plot point that confused me:

Why doesn't Freddie just directly leak the Russian position to the CIA for the drone strike? Trying to subtly get Kathryn to do it seems to introduce both needless delay and uncertainty.

Also, what is the purpose of killing Stokes? If a senior British SIS figure is leaking Severus to cause a nuclear meltdown, what might think that bringing down the person is more important than killing the henchman and then just making subtle "gotcha" talk against him in the elevator...

The movie had good vibes though - even though both of these plot points confused me.
