Katie is a character featured in Battlefield 4: Countdown to War.
After Shanghai police announced that all foreigners need to go to the Zhi You Tower to be evacuated, Katie and her husband Chip met with Hannah, who turned out to be an old friend of Katie's, as well as her "husband" and "brother". Chip then started to question Hannah and her brother's presence in the tower as they were not foreigners.
It was at this time that the bandages fell off of the face of Hannah's brother, revealing his true identity as Jin Jie to Katie who instantly recognized him, much to Chip's ignorance. As people were starting to stare, Kovic quickly wheeled the injured Jin Jie via trolly into the nearby elevator and went up the tower.
