Mei-Ling Cho was a Chinese Intelligence agent. She is portrayed by Gwendoline Yeo. She is in the United States to rescue her brother Lee Cho, a low level diplomat working at the Chinese consulate who has been kidnapped by Chinatown Triad leader, Ben Lo Pan. She is on a rogue assignment, without her government's approval as they refused to save her brother. The team unintentionally foil her attempt when Sarah and Casey enter the club and get involved in a gun fight, while Chuck inadvertently helps Ben Lo Pan escape, who attempted to escape on his own with his wheelchair.
