He is a resident of the Tower and can be found on the upper floors in the medical ward. He works alongside Doctor Lena, acting as her nurse.
During the main story questAwakening, he will deny Kyle Crane access to the medical ward until he has spoken to the boss.
Later, during the quest Tunnel Vision, Crane makes contact with drug producer Ryan, in need of phenyl-nitrate for his 'insomnia pills' which he sells to Rais' Gang. After collecting the needed chemical, Kyle instead takes it to Aman, who provides Dialovon to substitute the phenyl-nitrate. When Kyle takes Ryan the delivery, he goes off to make his last batch, which will cause the thugs to fall asleep.
