As bad at communicating as ever, Oliver neglected to fill Diggle in on this development, and Digg was waiting for Oliver to return to his focus on his position as mayor and father.
Oliver did eventually break the news and apologize for stringing his best bro along, and Diggle accepted the apology and Oliver back as leader and the Green Arrow.
Thanks to a chat with Thea before her departure, Oliver had decided that he was the best version of himself when he was the Green Arrow.
The atmosphere in the Arrow bunker was tense from almost the very beginning due to the fact that Oliver wasn’t giving up the hood and returning the mantle of the Green Arrow to Diggle, who was honored and touched to be trusted with the responsibility in the first half of Season 6.
