Arrow season 3: Official plot descriptions of final three episodes tease the fate of Oliver and Team Arrow

Just three more episodes to go before Arrow season 3 ends. What's in store for Oliver and Team Arrow? Check out the official descriptions of the finale episodes:

Synopsis for episode 21 titled Al Sah-Him, reads: "Oliver goes through a rigorous transformation. The League of Assassins sets their sites on Nyssa (guest star Katrina Law), who is back in Starling City training Laurel. When Nyssa realizes they are coming, she arms up to face them alone but Laurel asks Felicity and Diggle to help protect her new friend."

The official description for the penultimate episode of Arrow titled This Is Your Sword, contains some interesting spoilers about the ascension of Al Sah-Him, not to mention the surprise return of a couple of fan-favourite characters: (via ComicBookMovie)

"Oliver/Al Sah-Him 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 and delivers some shocking news. Meanwhile, Malcolm makes a surprising offer to Team Arrow and Thea goes to see Roy (Colton Haynes)."

And here's the plot synopsis for the season 3 finale episode titled My Name Is Oliver Queen:

"Everyone's lives are in danger as Ra's al Ghul puts forth his final plan. Oliver/Al Sah-Him must decide if he's strong enough to take on this new role and what it will mean for everyone on Team Arrow, and his soul."

Arrow season 3 airs on Wednesdays at 8pm on The CW.
