Yeah, and also, he seems to be looking at it in terms of "Shen Wei is secretly the Envoy", and not "the Envoy is secretly Shen Wei". Even though both are true.

Oh yeah, so true! Good point. And I think the "Why are you really here?" is aimed at the Envoy, because it makes zero sense to wonder that about Shen Wei (unless it's "Why are you really helping the SID?").

IOW, Shen Wei's compartmentalisation is so absolute, it's hard to stop thinking of them as different people. (I do it myself, all the time. *g*)

But if, say, Zhao Yunlan just went and called him Hei-laoge, do you think Shen Wei would actually stand there and claim he had the wrong man?

Oh. Wouldn't he have to? Look at him like he's mad and say, "I don't understand"? He's not ready to collapse his compartments yet, after all.

True. (And they must suspect that Zhu Jiu is involved, because of the play for the Hallows, surely.) Hmm... Maybe they both just have unshakeable faith in Lin Jing's abilities, whether or not he gets the data he needs? ;-p
