The CW has released the official teaser for next week's episode of Arrow, titled "Next of Kin."
In the trailer, John Diggle suits up as the Green Arrow, with Oliver egging him on to be a better hero.
In the episode, a rogue black ops team led by Onyx (guest star Chastity Dotson) breaks into Kord Industries and steals something lethal. Oliver (Stephen Amell) struggles to connect with William (guest star Jack Moore) so he reaches out to a surprising source for help.
Earlier tonight, Amell took to Twitter to cryptically congratulate his co-star, David Ramsey. For those who've seen tonight's episode, the tweet takes on a whole other meaning - as it references Ramsey's character, John Diggle, taking over as the Green Arrowfrom Oliver Queen.
The twist was certainly an unexpected way for Oliver's identity crisis to resolve, and it's unknown exactly what kind of impact it'll have on the show going forward.
You can see the trailer above, and official stills from the episode below.
