Garvin Quinn

Garvin Quinn was the engineer on the Rifleman Bank Station in Deus Ex: Human Revolution - The Missing Link, and functioned both as a merchant and Netanya Keitner's contact.

Background
After an indeterminate time working under Janus, an agent identifying as "no1" was eventually chosen to infiltrate Belltower's ranks as a low ranking Irish engineer named Garvin Quinn, with the intent of damaging their reputation. He then eventually approached Lt. Colonel Netanya Keitner, the second in command officer on the base, and recruited her to gather incriminating evidence under the guise as an Interpol agent.

Upon Jensen's discovery and capture by Pieter Burke, Quinn saw an opportunity for the use of a neutral pawn in his plan, and ordered Keitner to release him. After guiding Jensen to a meet up point with Keitner, he eventually met Jensen in person (under his engineering guise), and provided him with supplies. After Jensen required an optical augmentation modifying to reach the lower labs, he also used his engineering skills to assist him.

After the base was placed on high alert and Keitner was killed, Quinn contacted Jensen wishing him good luck and telling him he left some supplies in his now unlocked shop. Contrary to what he said, however, Quinn actually remained on site to communicate with an unknown superior and to prepare for Jensen's success.

Upon Pieter Burke's neutralization, he then revealed his true affiliations and motivations to Jensen, before rewarding his work by transporting him to a second ship heading straight to Omega Ranch. After Jensen's departure, he can be heard discussing Jensen's potential with Janus, before being dismissed due to Jensen's obsession with Megan Reed.
