He serves as Racetrack's co-pilot during the rescue mission for the Caprica resistance. When their Raptor misses their jump, they discover a habitable planet which is later dubbed New Caprica. After returning to the Fleet, McCall and Edmondson are commended for the accidental discovery (Lay Down Your Burdens, Part I).
Over a year later, during the planet's occupation by the Cylons, Skulls is Racetrack's ECO during their missions to detect communications from the resistance movement on New Caprica, in which they are eventually successful (Occupation).
On a routine patrol around the Fleet, his Raptor suffers from an engine and RCS malfunction, due to impurities in its tylium fuel. Unable to regain control and on a collision course with Colonial One, he and Racetrack are forced to eject from the Raptor. The craft collides with Colonial One, causing severe hull damage and several injuries, but no fatalities (Dirty Hands).
