Having been presumed-dead for 15 years, 2046s Star City finally saw Oliver Queen return to the public eye and become the Green Arrow once more. Even though wed only been introduced to Old Man Ollie in this very episode, it was still an emotional and impactful moment to see the Emerald Archer don his iconic hood once more in order to help Sara Lance in her attempts at rescuing the kidnapped (and soon-to-be executed) John Diggle Jnr./Connor Hawke/Green Arrow.
