It is later revealed that Blue Team and the Chief had learned of a plot against Sekibo, prompting their arrival at the delegation. The Master Chief then escorted the Sangheili delegates to safety, together with a mortally wounded Richard Sekibo. The Chief murdered nine Sapien Sunrise infiltrators but ten of Sekibo's security detail were killed, along with three Sangheili guards. By the time investigators realized that the attack was the work of Sapien Sunrise, a flow had revealed false information regarding the events into the UEG public, causing outcry from the Master Chief and the SPARTAN-II Program in general.
Sooner or later in 2558, Richard Sekibo, the Outer Colonies Ambassador had finally scheduled a long-awaited peace talk between human and alien delegates. Just as the peace talks were coming to a close, John-117 apparently attacked the embassy at which the event was being held in and killed nineteen human safety guards. The delegates were escorted away by John to security. John also abducted Sekibo, whose dead body has been found in a nearby area the following day.
