Will Team Arrow reunite to save Starling City?Facebook/Arrow

When "Arrow" returns on The CW with season 4, it is likely to focus on twists and turns in Oliver Queen (Stephen Amell), Felicity Smoak (Emily Bett Rickards), John Diggle (David Ramsey), Thea Queen (Willa Holland) and Laurel Lance's (Katie Cassidy) lives.

While the onscreen power couple of the show will be dealing with various challenges faced by them as partners, the ex-military bodyguard might not just have a costume change but may also get influenced by the villains.

"Diggle is gonna have some sort of helmet/armour thing going on next season," Ramsey told DC Entertainment, adding, "There is a big bad guy that Diggle be involved with next season. It is suppose to be a big season for diggle."

Meanwhile, Amell said that he would like to see some Thea and Laurel centric episodes in season 4. He even stated that the previous sequel was a "transitionary season" and will set up the upcoming sequel.

In the meantime, Cassidy teased that she could reprise her role as black canary while Rickards teased about Olicity helping Roy Harper aka Arsenal (Colton Haynes) and Thea.
