Summary: As Oliver talks to Laurel at her grave, he is joined not by Felicity, but Sara Lance, who upon seeing him is reminded of who she is, what she stands for, and what she discovered. The White Canary and the Green Arrow, recognizing the time of heroes fighting in the light of day has long since passed, fight from the shadows as a new threat emerges. His name: Prometheus. M to be safe.

As with all my work, its not gonna be complimentary to Felicity post-Season 2.
