Panetta's mood was quite complicated, because when he watched Gao Yi and Yuri disembark from the plane at the same time, he showed obvious hesitation and conflict.
The CIA has never had a particularly good reputation. Betraying its allies is the CIA's creed, burning bridges is the CIA's habit, so don't say the CIA has no promise not to harm Yuri, even if they do, that's not a reason for the CIA to let Yuri go.
Panetta was polite to Yuri, firstly, for the sake of Gao Yi, and secondly because Yuri's background was a complete mystery to him.
The second point was the most important.
Panetta only hesitated for a very short time, then immediately showed a smile and warmly extended his hand to Yuri.
"You've had quite a task."
Panetta was making small talk, while Yuri, without any change in expression, caught on to Panetta's words.
"It's my duty, after preparing for decades, there has to be an opportunity to put it into use."
