|Allegiance||Diego's Group (formerly)|
Robbie was apart of a group of lost children led by Diego in Richmond, Virginia.
Robbie is first seen at Diego's shelter, were the group stayed. When Hal arrived, Robbie watches as they have a standoff. While Hal begins to leave he sees Robbie, seeing the hunger in the kids and decides to take them back to the 2nd Mass to give them food. Diego takes a few children back to the 2nd Mass camp to retrieve the supplies. While they are away the shelter is attacked by skitters, and when Diego and the rest arrive back they find Robbie's leather jacket with blood coated on it. Robbie was taken to a harnessing factory with the rest, and when Diego tried to save them he was also captured. While Robbie was tied up in a room being held he was saved by Maggie's squad from the 2nd Mass that arrived to the facility.
It is unknown what happened Robbie when Diego's Group were split when the aliens later attacked their group. Robbie did not make it to the meeting point as said Jeanne Weaver and it is possible he was harnessed like Diego.
