Screen captures from the promo trailer for the Arrow episode Unthinkable

There’s a lot going on in the promo trailer for the Arrow season finale, which is called “Unthinkable” – you can see that promo trailer video here – but thanks to Mr. Video, you can now look and see what was going on shot for shot, as we now have screen captures from the promo trailer.

Roy with a mask! Fateful confrontations! Drones! Deathstroke! Black Canary! Team Arrow United! This is going to be a great one.

Enjoy the caps below, and if you like them, as always, please just link to GreenArrowTV’s gallery rather than copying the photos onto your own websites, Tumblr pages, etc. (This means you, too, CBM.) Thanks!
