2008: JBA Crisis
Caleb was assigned to assist Carson Moss during the JBA mission in New York City. The mission objective was to secure the Red Mercury devices at predetermined locations for detonation, intended to destroy New York City. Sam Fisher, a double agent working for the NSA, was systematically eliminating JBA members and disabling the Red Mercury devices. After 'team one' went silent, Carson Moss ordered Caleb to shut down the light in the office building where they planted some of the Red Mercury devices.
It is unknown what happened to Caleb, but he was likely either killed or knocked out by Fisher. It is also possible that he was arrested by police officers after the building was secured by SWAT.
- Caleb was ordered by Moss to disable the lights. Disabling the lights allowed Moss' team to see in the dark using Night vision goggles they had brought with them on the mission.
- Caleb is only mentioned in Version 2 of Splinter Cell: Double Agent.
