Engineering Technician

Duffy

observant collaborative analytical professional skeptical

Duffy works as an engineering technician on the USS Enterprise-D, reporting to Geordi La Forge. He moves nitrogen canisters in Cargo Bay 5, spots a broken seal leaking Invidium that contaminates him and spreads ship malfunctions. In Ten Forward, he mocks Reginald Barclay as 'Broccoli' until his glass liquefies from the contaminant. In Main Engineering, he pitches magnetic quenches and diagnostic sweeps, questions Barclay's tests, links injector jams, anti-grav crashes, and transporter glitches, recalls his cargo bay role, nods to the Invidium theory, and directs Wesley on power routing to purge the threat.
