Now the story is starting to take off. It'll have us wondering all the way to the end what kind of ruling is in 31's best interest.
The dialogue between L'Haan and Sorak brings me back to some of the points I've made about Zero Sum Game's cliffhanger ending. For one, the only scenes truly narrated from Sarina's point of view were while she was in Breen custody and the final scene of the novel. Secondly, that it ended where it did suggests more is happening than the simple finding out his wife is a Russian spy premise.
Finally, a rhetorical question, wasn't Sorak the guy who first recruited Sloan into the Bureau? I'm guess that arrangement is analogous to Aiman al-Zawari being Osama bin Laden's mentor, but bin Laden was ultimately the one in charge.
