Walter Steele ~ "Your father would be very proud of you, Oliver".

Walter Steele is described as "a commanding, upper-crust man". He is also very loyal. This is proven when he learns about Robert's fate and tries to do everything he can to solve his best friend's murder. He is intelligent, and calculating. Despite the divorce with Moira Queen, Walter still loves Oliver and Thea and will not hesitate to help them in anyway he can. He was not only willing to give Oliver a loan to help him buy the shares he needed from Queen Consolidated, but was also happy Oliver knew he could turn to him whenever he needed him. Walter also appears to have forgiven Moira, and has asked her to run for mayor. He's also a very bad liar.

Walter is shown to be very caring for the people around him, even his employees. He attempted to warn Doug Miller he would be a potential target for The Hood, a trait which turned out to be his downfall. Despite marrying Robert's wife, Walter was very loyal to Robert, going as far as to investigate the ruins of the Queen's Gambit when questioning the manner Robert Queen died.

Walter has an RP (received pronunciation) accent, and the emotional self-control often associated with a boarding school education.
