So, I see it's been raised a few times, but how does everyone think that Oliver will reclaim the Arrow (or Green Arrow) identity next season? And how will he stop everyone from suspecting that the "new" Arrow is Oliver Queen after he's already been arrested twice on suspicion of being the Arrow?
The general public and the vast majority of the Starling City Police Department, with the exception of Captain Lance, believe that Roy Harper was the Arrow and that he was killed in prison while awaiting trial.
Will the general public simply view the return of the Arrow as being someone else who has adopted Roy Harper's vigilante identity? Will Oliver create a new costume and somehow publicly announce a new superhero identity as "Green Arrow" to try and differentiate himself from the Arrow? Will Oliver and Felicity come up with some sort of technological trickery (i.e. holograms) to ensure that Oliver and the new Arrow are both seen at the same time, in the same place in order to remove any suspicion on Oliver.
Will the general public and Captain Lance accept the return of the Arrow? They seem to have been fine with Black Canary's continued exploits. After Roy Harper's death, it didn't really seem to matter to anyone that there were other vigilantes out on the streets. Will the general public and Captain Lance accept the return of the Arrow if he's killing people? Oliver seems to have abandoned his "no killing" code and will presumably go back to using lethal force when necessary.
Or will Oliver "save" the city in some other way, for example, by running for mayor. And then once he becomes mayor, maybe he'll publicly praise the various vigilantes and only then resume his work as the Arrow? And if anyone gets suspicious, he'll simply direct the SCPD to stop investigating the secret identities of the vigilantes (which itself would probably be pretty suspicious)?
