Arrow Season 3 Spoilers: New Episode 21 'Al Sah-Him' Promo Photos Show Oliver Queen in League of Assassins Costume

Wednesday's new episode of the CW's Arrow, entitled "Al Sah-Him," will feature the first action for Oliver Queen since he donned the League of Assassins uniform at the end of the previous episode. Some new photos from the episode show Ollie in costume.

E! Online has the exclusive photos here. You can also see Diggle consoling a crying Felicity in the pictures.

The official description for the penultimate episode, entitled "This Is Your Sword," reveals that Roy (Colton Haynes) returns, Nyssa survives the events of next week's episode, and Oliver moves closer to becoming the next Ra's al Ghul. Check it out below:

"AL SAH-HIM TAKES HIS FINAL STEPS TO ASCENSION; ROY AND THEA REUNITE — Oliver/Al Sah-him (Stephen Amell) finishes his training and is left with two final tasks to become the next Ra’s al Ghul. Ra’s (guest star Matt Nable) threatens Nyssa (guest star Katrina Law) and delivers some shocking news. Meanwhile, Malcolm (John Barrowman) makes a surprising offer to Team Arrow and Thea (Willa Holland) goes to see Roy (Colton Haynes). Wendey Stanzler directed the episode with story by Erik Oleson and teleplay by Ben Sokolowski & Brian Ford Sullivan."

In case you missed it, a new extended promo for "Al Sah-Him" has been released, and it looks like Oliver is going to cross paths with his friends sooner rather than later, but in a way he'd rather avoid. Check it out below:

Here is the official description for the episode:

"THE LEAGUE OF ASSASSINS SETS THEIR SIGHTS ON NYSSA - Oliver (Stephen Amell) goes through a rigorous transformation. The League of Assassins sets their sights on Nyssa (guest star Katrina Law), who is back in Starling City training Laurel (Katie Cassidy). When Nyssa realizes they are coming, she arms up to face them alone but Laurel asks Felicity (Emily Bett Rickards) and Diggle (David Ramsey) to help protect her new friend. Thor Freudenthal directed the episode with story by Beth Schwartz and teleplay by Brian Ford Sullivan & Emilio Ortega Aldrich (#321)."
