The head of Navarro's technical crew in the 2240s was Quincy, a man of skill and responsibility. Not nearly as hostile as Arch Dornan, he oversaw the work of mechanics and maintenance teams throughout the base as well as kept an accurate inventory of its assets. One of his main duties was the safekeeping of vertibird plans.
He had a short temper towards those who, in his eyes, were incompetent or clumsy, especially when it resulted in loss of inventory. He also had a long running rivalry with Raul, the Enclave mechanic.
While looking for K-9's repair parts, if the Chosen One tells Quincy that Raul in the North-West hangar sent them for the plans, there will be a dialogue option to tell Raul that Quincy wants to see him, whereupon Raul will walk off to beat Quincy up, leaving the Chosen One free to retrieve the K-9 motivator and the vertibird plans during the fight.
