"Arrow" has new bits of details that fans will need to look out for, especially towards the story of Felicity Smoak. As it turns out, there may be darker secrets behind the character than what was already revealed in the past.

Smoak, played by Emily Bett Rickards, already had a rather controversial past throughout the entire flow of "Arrow" to this day. After surrounding relationships in the past with the likes of Atom (Brandon Routh) and even the Green Arrow (Stephen Amell), the death of one in particular may have triggered an even darker side to the beautiful geeky character.

According to Comic Book, the second half of the existing season of "Arrow" highlights how Felicity started to become a different person after the death of Detective Billy Malone, played by Tyler Ritter. Other clues were also justified by the fact that Felicity was given a jump drive by Helix hacker Kojo Sledgehammer (Kacey Rohl), one which holds stolen classified data from the NSA. Her actions started off with simply using these files to free Diggle, further leaning to the bad side as she lies to Curtis and Rory. She then blackmailed an executive with the stolen data, had the two aforesaid members disguise as Bratva enforcers to do the deed with her.

As an interview with Entertainment Weekly explained, the "Arrow" star is yet to find out what the real score is with Felicity, saying that he knows she is up to something, without opening up to her once love interest. Amell says that it is something that Felicity does not want to talk about with Oliver, until an adult conversation comes about sometime along the way.

The upcoming episode of "Arrow" is expected to show the answers to the said questions, alongside a further look at the history of Wild Dog, otherwise known as Rene (Rick Gonzalez). This will also pit the hero in a situation he might need to solve the case as Oliver Queen and not the vigilante archer.
