You know, in "Passage II," at the end of the episode, when Irinia was safe and sound in her holding cell, she said something to the effect that she wanted to tell Sydney why she shot her back in Taipei. The reason Irinia gave was the fact that a superior was in the next room over to test Irinia, where her loyalty lies. When did she decide to help the CIA? Obvoiusly, before Taipei, but what was the exact event? Will this be revealed in later chapters? What do YOU think?
