John Diggle

Batwoman: Sent By Lyla to check up on the Crows because probably the Crows are funded by A.R.G.U.S.

The Flash: Came by to visit while asking Team Flash to look for sonething and also help with the big bad or the meta of the week

Supergirl: Maybe with Lex finally arrested and ARGUS and the DEO share the same earth and due ti lexs level of threat Argus Takes him into custody With Dig overseeing this and is probably there ti help out fir an episode

Superman and Lois: Helps Clark find Captain Luthor

Is the next episode of Superman and Lois the episode with John Diggle as Green Lantern?

It an Arrowverse now and Diggle will need to make an appearance. He will make an one episode Appearance in 5 other Arrowverse shows and direct a different episode where he is not in it.

I really loved the fight scene between Digg and Oliver (6x17). It was so emotional, so intense, soooo good! It’s one of my favourite across the entire Arrowverse!

Imo, Digg had no right to ask for the Hood! Oliver Queen was and always will be the Green Arrow
