Arrow: Stephen Amell Self-Censors a Season 8 BTS Photograph

There's a lot of secrecy surrounding Arrow's eighth and final season. But while there's very little known about the story and setting, there have been multiple confirmations of throwbacks to previous seasons. Not only will Moira Queen, Tommy Merlyn and Adrian Chase return for the series' final season, we may even get throwbacks to Season 3 with the return of Katana.

And now, we have another mystery to dig into. Series star Stephen Amell has shared a behind the scenes photo from the Season 8 shoot -- a photo he's self-censored, hiding the costume he's wearing.

The photo appears to be taken in a forest, which some might see as a sign that Season 8 will take us back to Lian Yu, the island where Oliver Queen was marooned for five years. The plot thickens when you dig deeper into the censored costume. Portions of it can still be seen, adding fuel to the theory he's wearing Oliver's Season 1 costume.

The big question remains: are all of these throwbacks flashbacks to prior seasons -- or is there something else going on here?
