Whilst it was shocking enough to see all of the foot and leg-based puns and lines thrown Felicity Smoaks way during Unchained, the biggest shocker for Arrows resident super genius was saved until the episodes final moments as it was revealed that her dad is in town. Not only that, unbeknownst to Felicity, her daddy dearest is actually The Calculator, the rogue who shes been raging cyberwar on throughout the episode. How this plays out in the future remains to be seen, but the fact that this villain is going to be getting to know Green Arrow shortly throws up plenty of possibilities. Plus theres the intrigue of what Felicity will do when she inevitably finds out the truth about her fathers villainous alter-ego.
