In case you don't remember, the last time we saw Oliver Queen, he had cut a deal with the FBI, giving up his freedom in exchange for the safety of the rest of the Team Arrow and Star City. But little does Oliver know that getting himself imprisoned and exposing his true identity as the vigilante would only attract more trouble, especially when he is locked up with a bunch of notorious criminals.

Ahead of the season 7 premiere, The CW will be releasing a brand new trailer - most likely on Monday - teasing the gruesome events that ensure in the high-security Slabside Prison, where Oliver is spending his days. The news comes from the horse's mouth itself. Taking to social media over the weekend, actor Stephen Amell himself shared a "sizzle reel" accompanied with the caption, "Dropping Monday..."

If our past experiences are any proof, Amell is most likely teasing a brand new trailer drop, that may focus on an unmasked Green Arrow in prison.

Moving on, things would also be getting bloody and brutal for Oliver - as reflected in the latest picture tease - as he picks up fights with his fellow inmates at the maximum security facility. Perhaps the latest trailer is going to offer a glimpse of these hard times, as had been hinted by Arrow director James Bamford in an interview earlier.  

"Beth Schwartz [Arrow showrunner] and I had a phone call with BNSP, which is our censors... a very lengthy phone call about a particular scene that we never had before," Bamford had revealed back in summer, dishing on what's coming in the forthcoming season of the 'Arrow'.

"So, we are really trying to push the limits on the show in the gritty factor. We are trying to go as far as you can go within the confines of our network and what is expected of us and what we can do and can't do. We are not on Netflix, so we will never be able to X, Y, and Z, but we are damn sure going to try," he added.

Meanwhile, the premiere of Arrow (and other major DC superhero shows) would be setting the stage for this year's annual crossover event, titled 'Elseworlds'. Apart from showcasing an interconnected story - reportedly spread over episodes of 'Arrow', 'The Flash', and 'Supergirl' from December 9 to 11 - the much-awaited event will also feature a debut by Ruby Rose as Batwoman. 

Until the season premiere and the annual crossover, though, Amell is here to keep fans informed and excited about the upcoming series of events. "Just wrapped. Read the crossover again. Can’t sleep," the actor recently tweeted. 

'Arrow' returns with season 7 on Tuesday, October 9 on The CW.
