Dr. Gill is an obstetrician residing in Star City. He is also one of the few people to know that Malcolm Merlyn was Thea Queen's biological father.


When Gill delivered Thea, there were complications in the birth, resulting in Moira Queen revealing to him that Malcolm Merlyn, not Robert Queen, was her daughter's biological father.[1]

About 19 years later, Moira paid Gill off through a wire transaction on Tempest in exchange for his silence on Thea's parentage during her mayoral campaign.[2]
