Cordelia discovered new clues at the White House that she had missed on the night of the state dinner, which allowed her to piece together the sequence of events and identify the murderer. This included understanding the movements of the body and the staging of the crime scene.

After A.B. Wynter was killed in the Yellow Oval Room, engineer Bruce Geller moved the body first to the Lincoln Bedroom, then carried it upstairs to Room 301, placing it next to a sleeping Tripp Morgan. Later, Tripp panicked and moved the body down the hall to the Game Room, where he staged the death to look like a suicide.

Lilly was motivated by fear of exposure after Wynter discovered evidence of her embezzlement and threatened to expose her. In response, she attempted to poison Wynter and ultimately killed him by striking him with a clock in the Yellow Oval Room.

Bruce moved the body to protect Elsyie, whom he suspected; Tripp moved the body again to avoid blame and staged a suicide with a knife and a fake note planted by Lilly. Lilly impersonated Elliot to keep people away from the Yellow Oval Room and ordered the passage to be sealed to cover up evidence.

The Yellow Oval Room was the location where A.B. Wynter was murdered. It was central to the mystery, as the crime scene was manipulated and access was controlled to hide evidence. The episode's title and key events revolve around this room.
