It's the end of an era.Arrow's Stephen Amell announced that he finished filming his last scene with longtime co-star David Ramsey. "Just wrapped my final scene with David Ramsey," he wrote.

Oliver and Diggle have been fighting side-by-side since early Season 1. While the two have not always got along -- including a brief stint where Diggle actually left the Team Arrow in protest of Oliver's leadership -- they are loyal partners and best friends who would give their lives for one another.

With Amell not only announcing that he finished filming with Ramsey, but also every series regular, it is only a matter of time before Arrow closes up shop for good.

Airing Tuesdays at 9 p.m. ET/PT on The CW, Arrow's final season stars Stephen Amell as Oliver Queen, David Ramsey as John Diggle, Rick Gonzalez as Wild Dog, Juliana Harkavy as Black Canary, Katie Cassidy as Black Siren, Katherine McNamara as Mia Smoak, Joseph David-Jones as Connor Hawke and Ben Lewis as William Clayton-Queen.
