8 Things to Know About Tonight's Season 3 'Arrow' Episode "This Is Your Sword"

The penultimate Season 3 episode of the CW's Arrow, entitled "This Is Your Sword," airs tonight, and the following are 8 things to know for what should be an action-packed hour.

TVLine has compiled the list and prefaced it by saying "the seven-day wait until next week's season finale will be torturous." So let's dive right into it:

1) Diggle, Laurel, Felicity, Malcolm, and Tatsu aka Katana all descend on Nanda Parbat to try and stop Ra's al Ghul's plan to unleash the Alpha and Omega bioweapon on Starling City, which leads to an epic fight sequence. They, alongside some surprise help from The Atom, take on the League of Assassins in what "might be the show's lengthiest and most impressive [fight scene] to date," and that's really saying something considering what we've seen on this series.

2) Diggle is really mad at Oliver, and those anger issues don't appear to be dissipating anytime soon.

3) Tatsu convinces Felicity to fight for Oliver, but it might be too little, too late, as Oliver reveals to Felicity that he's getting married to Nyssa. Furthermore, Tatsu reveals to Felicity something that Oliver told her when she helped him heal after his duel with Ra's several months ago.

4) Thea goes to see Roy, who now goes by the name Jason and works at an auto shop. This leads to a scenario that will "definitely evoke excitement."

5) Nyssa will not go down the aisle quietly.

6) There is a major business move of some kind.

7) Malcolm delivers two of the biggest twists in the episode.

8) Someone says the line, "You lost my trust. You lost my respect."
