Exciting and intense episodes will continue on 'Arrow' Season 4. Also, a lot of twists and new storyline could be done. One of which is the speculation that a new superhero is set to join in the team. Rumors are spreading across the internet that John Diggle becomes a Green Lantern in the upcoming season. Another, the most-talked about pair will begin their journey as a couple. They will spend a quality time together.

'Arrow' Season 3 ended on an unexpectedly happy note, as Oliver and Felicity riding off into the sunset. Thus, it is expected in Season 4 that fans will get to see more of Olicity romance. The last time we have seen them together was quite intense, and who could not remember it?

In a recent interview, Emily Bett Rickards, who portrays Felicity, is pretty positive that Season 4 storyline will delve more into Olicity's romance. She said that they are positive to give people what they want, as they always had. But fans can expect another intense Olicity sex scene? This is not impossible, as the couple has to spend some quality time alone away from Starling City and Nanda Parbat.

Meanwhile, another twist that could probably happen in 'Arrow' Season 4 is the possibility of Green Lantern to join the team. If you happen to remember, Ollie told John Diggle to wear a mask, as they parted ways in the last part of Season 3. The mask could keep his identity safe, especially that Diggle had to protect a family.

The scene sparked the rumors that Diggle could become Green Lantern. This may not be impossible to think because writers of the show is doing their best to make great twists and turns in 'Arrow' Season 4, and it could be one of them. If Diggle will not become Green Lantern in Season 4, we are sure that he will be wearing a mask and fighting against crimes. He might be considering an alias, but that remains a mystery for now.
