MI5 would never determine he was CIA based solely on a few words from Yang Yi, so Brian must have done something to influence MI5's judgment.
What did Brian do?
"What did Brian do?"
"He..."
After hesitating for a moment, Kate said, "Actually, he didn't do much, just tried to assassinate you twice, and then when we were surveilling the hospital, we used all the typical CIA tactics. But what deeper meaning lies behind Brian's actions, you'll have to ask him yourself. Things have been very tense; we just did whatever Brian said."
"So Brian was in charge of everything?"
"No, it was Zhang Yong."
Yang Yi was somewhat surprised, "Everything was overseen by Zhang Yong?"
Kate spoke softly, "Brian's health isn't good; he can't leave the safe house, so he's only responsible for controlling the overall direction. Paul will inform us about the specifics, while Zhang Yong is in charge of commanding the rescue operation."
