Also according to Amell, some of the characters that were never really close or involved with each other in previous seasons will unite and interact in the upcoming fourth installment.

According to Cinema Blend, one of the newest elements that will be introduced in season 4 is Thea Queen as a masked superhero. In season 3, Thea was trained by her father Malcolm Merlyn and later on finished in the Arsenal costume with her own bow and arrow in hand. However, not much has been told about Thea's backstory and season 4 will somewhat be about her.

Meanwhile, season 4 will also feature different dynamics now that Oliver ran off into the sun with Felicity. Following his departure, Thea will team up with Laurel and Diggle but fans are worried that they may not be able to complete their tasks like how Oliver did.

With this, Amell confirmed that fans need not worry because Oliver will be back and sometime in season 4, he will decide to wear his costume again and become Arrow once more.

"Arrow" also stars Katie Cassidy as Black Canary, Emily Bett Rickards as Felicity, Willa Holland as Thea, David Ramsey as Diggle and more.
