The level of secrecy surrounding Yang Yi's identity was so high that the vast majority of the CIA didn't even know he existed, let alone what crime he had committed.
So when Yang Yi returned to CIA headquarters, his appearance did not elicit any reaction, because even though some people knew that their Deputy Director Aaron had died at the hands of someone codenamed Sea God, they did not know that Yang Yi was Sea God.
Walter greeted Yang Yi at the door.
Strictly speaking, Yang Yi and Walter had a fairly good personal relationship, especially after Yang Yi gave Walter a car, so both professionally and personally, Walter was very pleased to see Yang Yi again.
First came a big hug, then Walter cheerfully said, "So happy to see you again, brother. Congratulations, not only did you succeed, but you also made it back alive."
Yang Yi said with great emotion, "Yeah, I made it back alive. It's great to see you again because I really thought I'd never be able to stand here again."
