Well anyway here's a drink on the house for a lucky son of a gun.
He is working as Clear Sky's bartender and dispensing food to the other members. He is apparently known among his comrades as a master of dirty jokes. According to Cold, he went to the zone saying that there was no place for him in the outside world.
Scar visits Cold's bar almost immediately after waking up in the Clear Sky base. The jolly bartender tells Scar about his faction and the people in the base, as well as his own personal story. During the war with the Renegades, Cold is the only source of trade with food and drink items.
