Arrow Trailer Teases Returns, 'Olicity,' Black Siren, Alliance With [Spoiler!?]

The final five episodes of Arrow Season 5 feature a flurry of returns (and “returns”), including a potentially surprising Deathstroke encore.

In a new trailer released on Thursday (and embedded above), Adrian Chase aka Prometheus has been in the wind for a week, but a final face-off with Oliver seems inevitable. Familiar faces in unexpected places, meanwhile, include Yao Fei and Evelyn/Artemis, while Katrina Law’s Nyssa al Ghul resurfaces rarin’ to teach her big sister Talia a lesson. (“Training day,” anyone?)

You’ll also see Team Arrow clash with Helix-affiliated Felicity, who appears to entrap Oliver at one point. And yes, there’s a cozy “Olicity” clinch, though I will remind you that Episode 20 features some new flashbacks, as the estranged lovers revisit their breakup.

The final image, though, is one to ponder, as Oliver slips into Slade Wilson’s Lian Yu prison to… invite his arch enemy to suit up??

Arrow returns Wednesday, April 26 with the first of Season 5’s final five episodes.
