As the penultimate season of Arrow nears its end, The CW has released the first images from next week's episode.

In "Spartan," the 19th episode of Season 7, John Diggle reaches out to estranged former colleague General Stewart following Team Arrow's disastrous setback. Portrayed by guest star Ernie Hudson, the photos from the upcoming episode suggest that the General may be linked to fan-favorite Green Lantern John Stewart.

The Emerald Warrior had been a Marine sniper before transitioning to civilian architect and member of the Green Lantern Corps. Given that an alternate-universe version of John Diggle had been strongly implied to be a Green Lantern, it further increases the likelihood that Hudson's character may be related to the classic DC Comics character.

In the new episode, Oliver Queen usse a new piece of information to turn his long-lost half-sister Emiko from the villainous Ninth Circle, while Felicity Smoak receives a tempting offer.
