Hilary was apart of a group of lost children led by Diego in Richmond, Virginia.
Hilary is first seen at Diego's shelter, were all the lost kids stayed. When Hal arrived, Hilary points her rifle at him. Diego takes Hilary and a few other children back to the 2nd Mass camp to retrieve extra supplies, and the following morning she plays soccer with a few other kids. When they arrived back to the shelter, it was destroyed by skitters and all the children were kidnapped except Jonny. Hilary later goes with Diego to the harnessing facility to get retrieve them. However, they are all captured and Hilary is tied up in a room with Diego and a few other remaining children. She is soon saved by Maggie's squad that arrived at the facility.
It is unknown what happened Hilary when Diego's Group were split when the aliens later attacked their group. Hilary did not make it to the meeting point as said Jeanne Weaver and it is possible she was harnessed like Diego.
