Series 9 Episode 4 discussion

[femaleBertieWooster]

I finally saw it and think it was one of the most, or the most, entertaining of all the episodes of all the seasons. The writers are doing a good job of confusing everyone about Lucas, Vaughn and Maya. I don't know what's going on but it is intriguing and hopefully will have a good payoff.

I read all the comments but don't remember anyone discussing the scene of the Chinese terrorists packing for home and saying that the mission was not a failure, they got what they wanted and we saw a photo of Lucas on the phone. (It may have been discussed on the first few pages of the thread which I read before I saw the episode and wouldn't have known what they were talking about.)

At some point I got the off the wall suggestion that Lucas was some sort of sleeper agent being woken up for his assignment. Why does Vaughn have power over him? Why would the Chinese hatch such an elaborate scheme just to check up on Lucas? And while we're on the subject, which end is up?
