Oliver and the gang will be back soon with "Arrow" season 4 premiering tomorrow, Oct. 7. In the season opener titled "Green Arrow," fans will see a glimpse of Oliver and Felicity's life as a couple after the former hung his hood and left Starling City, now called Star City, with the woman he loves.

It has been five months since the pair retreated to a life free of crime-fighting. But just when they thought trouble is over, Thea and Laurel (both have been busy keeping the city safe with Diggle) come to their doorstep in a bid to persuade them to return.

As seen in previous trailers, Oliver has his doubts in coming back to fight again because he knew the moment he left, he fully renounced his ways and set out to start anew. He seems to be planning to pop the question to Felicity too, as suggested in a teaser.

But with the emergence of Damien Darhk in "Arrow" season 4 and the villain sending out his "Ghosts" to terrorize the city he has been protecting for years, Oliver has no choice, especially after Felicity reminds him that there's no thinking twice when their friends need help.

Meanwhile, executive producer Wendy Mericle talked to IGN about the changes to expect with Oliver in "Arrow" season 4. She revealed that there will be more humor, which his character's comic book counterpart is known for.

Also, she said his happiness brought about by his relationship with Felicity will translate into "how he approaches his mission and how he approaches his life in general." She then added, "It's a different Oliver. It's still the same show and the same character but we're seeing new colors in him."

In the "Arrow" season 4 premiere, Oliver will come back to help out and will wear a ski mask to conceal his identity in the field. However, Diggle, who is still furious about Oliver endangering his wife and baby when he was trying to dupe Ra's Al Ghul, won't make him feel at home at all.

"Arrow" season 4 premieres tomorrow at 8 p.m. on The CW. Viewers can tune in via the CW app.
