Chu is part of the group led by Sesha Abinell which takes hostages aboard Cloud 9, hoping to get the Cylon prisoner Boomer in exchange.
He seems uncomfortable with the whole ordeal, hesitant to search the bathroom for more civilians, but still goes along with the plan.
Seconds before a second rescue attempt, Chu is suprised by Billy, who manages to take one of the guns he had on him and shoot Vinson.
As soon as Colonial forces pour into the Cloud 9 lounge, Chu is killed along with the rest of the hostage-takers (Sacrifice).
Notes
Chu could be named for Eric Chu, a concept art designer on the Cylons for the current Battlestar Galactica series.
