In the altered timeline, she maintained her position of an Allied intelligence officer and the advisor to the Commander. Lee was part of a team that entered Albert Einstein's time machine in order to prevent Yuri's domination. Soon after the war was over, she informed President Michael Dugan that a DEFCON 2 alert was sounded over the discovery of Yuri's army trying to control the minds of the entire world.
At the same time, she proved highly resourceful when doing her own research and seeking out information that would aid the Commander. From the start, she would occasionally speak to him in a colloquial manner or add her own thoughts to the briefing. She immediately took the role of informing him of his orders and the situation in the field. By the time the first iteration of the Third World War started, the Soviets managed to eliminate all Allied field commanders except one, to whom Lee was assigned. Lee was the top graduate of her class at West Point.
