The CW has released a sizzle trailer for the final episodes of "Arrow" season 5. The two-minute trailer features the return of both friends and foes of Oliver (Stephen Amell) and Team Arrow, including the highly-anticipated return of Manu Bennett's Deathstroke.

Adrian Chase (Josh Segarra) has been "picking" Team Arrow off, one by one, according to Oliver. In order to bring down Prometheus, Oliver is forced to return to the prison on Lian Yu and ask for help from his old foe Deathstroke. Bringing Deathstroke's mask, he approaches off-screen Deathstroke, who can be heard saying, "Hey kid, I'm glad you came back."

Also glimpsed in the trailer is the return of Nyssa al Ghul (Katrina Law), who is facing off against her sister Talia (Lexa Doig). Talia, who makes an alliance with Chase, greets her sister, "We have an unfinished business, sister," to which Nyssa responds by drawing out her sword. Meanwhile, other nemeses return to Star City to bring other threats to Oliver. Yao Fei threatens Oliver by saying that "those who are closest" to him are "fated to suffer." Derek Sampson (Cody Rhodes) and Konstantin Kovar (Dolph Lundgren) are also featured in the trailer.

Another intriguing part shown is the possible reconciliation of Oliver and Felicity's (Emily Bett Rickards) romantic relationship. Both are seen having an intimate moment after the pair end up trapped together. Laurel a.k.a. Black Siren (Katie Cassidy), meanwhile, surprises her father when she appears before him and chains her father up afterwards.

"Arrow" returns with new episodes starting on Wednesday, April 26 at 8 P.M. on The CW.
