In “The Secret Origin of Felicity Smoak” last week we got to see some really great things with all the characters as Felicity’s mom strolled into Starling City for some quality time with her daughter and we got to see how Felicity became the person that she was when she first met Oliver back in season 1. Pretty interesting stuff all around, and the larger mysteries of the season were also addressed, including a possible reveal of who might have killed Sara, though the why was/is still a mystery.
This week’s “Guilty” goes in a slightly different direction as it explores Ted Grant aka Wildcat’s past and what kind of an effect that his past has had on him, and what it might bode for the future of the show, specifically in relation to how Laurel sees him as a mentor and a friend. The episode does a fair bit to set up the debut of another villain, Cupid, while also dealing with the villain of the week, and the most important thing here is how Oliver has to make some really tough choices and how he is the only one, ultimately, who has to make them.
