Sneak Peek spoiler footage from the final scene of the Mid-Season premiere of The CW's "Arrow", showing the fate of 'Oliver Queen', aka the vigilante 'Arrow', who was gutted by a blade and tossed off a cliff by the villain 'Ra's Al Gul' in the episode "Left Behind":

"...in the aftermath of the fight between 'Oliver' (Stephen Amell) and 'Ra's al Ghul' (Matt Nable), 'Diggle' (David Ramsey) and 'Arsenal' (Colton Haynes) continue to protect the city in the Arrow’s absence. However, after three days without hearing from Oliver, they begin to fear the worst may have happened to their friend.
