He serves with "Easy" Esrin, who is his co-pilot aboard Raptor 718. While making a routine run to Zephyr for R&R along with Lt. Gaeta, Specialist Brooks, and two Number Eights aboard, a false alarm causes the Fleet to make an emergency jump. Raptor 718 accidentally jumps beyond the red line with no way to return to their original coordinates, effectively stranding it in space with only 20 1/2 hours of oxygen left (The Face of the Enemy).
- Both the script and the credits for this webisode refer to this character as "Finn." However, both this character's name and callsign are from the nameplate stenciled on the side of Raptor 718.
