In a recent report reveals that fans will be seeing a lot of Thea (Willa Holland) and Felicity (Emily Bett Rickards) in the second half of season 3 of Arrow, which is set to air in 2015.

Roy Harper To Replace Oliver As Lead In Arrow?

In TVLine's spoiler segment, executive producer Marc Guggenheim dished about Thea and Felicity's relationship, and suggested that things would start looking up for them in the rest of season 3.

"There's a lot of Thea and Felicity coming in the back half of the season. They'll be sharing quite a bit of screen time in 2015, and it's very interesting," Guggenheim said.

Slade To Return In Upcoming Episode Of Arrow 

Following the shocking mid-season finale which aired on December 10, in which Oliver (Stephen Amell) was slain by Ra's Al Ghul (Matt Nable), the promo for the upcoming episode was unveiled.   

In the promo somebody is heard saying Oliver is dead, as the camera pans atop the mountain top, where the duel between Ghul and Oliver took place, showing Oliver's limp body on a rock. That's about all the preview gives away about what fans can expect from the next episode, titled Left Behind, which is to air on January 21.

But while this seems to be the reality of the hour, it does not necessarily mean that Oliver is gone for good. As has been suggested by a Screen Rant report, the character could very well be resuscitated, noting it is a normal occurence in comic books. The piece goes on to specifics which could bring Oliver back to life like the immortalising Lazarus Pit, we were made aware of in the previous episode. The pit is also known to heal deadly wounds, perhaps even bring people back from the dead.
