Sure, Oliver Queen has been regularly compared to Bruce Wayne over the years, but it was sister Thea who did her best Worlds Greatest Detective impression here. Not content with merely brushing an uncashed $1 million cheque under the carpet, Thea does her own detective work and discovers that Ollie was actually in college with Samantha Clayton, a girl he claimed that hed never even heard of. Going even further, Thea soon pieces the puzzle together and works out that Samanthas son William is indeed the son of Oliver. The interaction between Thea and Ollie here was brilliant to watch, with it almost serving as a change in the dynamic between the pair and adding some impressive credentials to the character of Thea Queen.
