Can the arrow ever been the ordinary Oliver Queen again? just when he thought the battle against crime has been minimized to the lowest level, a new enemy is born.
Intriguing to find ourselves back on the island at the episode's end. More time away for Oliver from the city he's sworn to protect... Maybe he just wants to escape the Felicity heat.
The episode ends with a perfect bookend of Maseo and Oliver returning to Starling City with Waller in the past, and Thea and Oliver returning to the island in the present.
Indeed, this episode is a strange entry. You can't really call it a "biding time" episode, as it features many major shifts in dynamics and relationships, but it also retreads old storylines in the guise of the Vertigo plotline.
Oliver got to face Dark Oliver in the first installment, but the twist was a bit more interesting this time around as Laurel faced off against her dead sister, a much more complex relationship.
