He's described as being as mysterious as he is wealthy and recur as an acquaintance of the Queen family and prominent figure in Starling City.

Using the exclusive photos above and below, it appears that acquaintance is Oliver's mother, Moira Queen (Susanna Thomson), who seems to be paying a visit to what appears to be the office of one very Well Dressed Man.

The CW adaptation starsAmell (Private Practice) as Oliver Queen/Arrow, a hooded vigilante who returns home to Starling City five years after being presumed dead from a boating crash to carry out revenge upon the people who have transformed his hometown from the sprawling city it once was.
