"Arrow" season 4 may eventually see the end of Oliver Queen (Stephen Amell) and Felicity Smoak (Emily Bett Rickards).
In the previous episodes, Oliver and Felicity have always figured things out for the sake of their relationship.
However, in the upcoming 16th episode of the hit The CW series, Felicity will give her engagement ring back to Oliver.
The teaser for the episode showed Oliver talking to his ex-girlfriend Laurel (Katie Cassidy).
"This doesn't seem fair that I can save the city, but not my relationship," he told her.
In one of the scenes, Felicity could be seen removing the ring from her finger.
"I can't do this," she said.
Meanwhile, the episode will also see Diggle (David Ramsey) talking about the organization H.I.V.E.
"I can't believe H.I.V.E is silent just because Damien Darhk is in jail," he said.
The next scene showed Malcolm Merlyn (John Barrowman) talking to Damien.
"I was going ahead with Genesis, but not with you," he tried to prove that he's working with him and not Oliver.
In other news, "Arrow" season 4, episode 16 will also see the return of Cupid.
Previous episodes revealed that Cupid tends to be obsessed with anyone she lays her eyes on. At one point, she became obsessed with Oliver.
"Til death do us part," Cupid said.
Oliver could also be heard talking to Laurel and saying, "Felicity convinced me to re-save the city, and to not surrender to the darkness. But I don't think we can."
According to Melty, there's still hope for the couple to fix their issues because they've always done so in the past.
However, a shocking twist also awaits "Arrow" fans, and it's possible that this may have something to do with the two characters.
Meanwhile, photos from the set of The CW series were recently released online.
One of the photos revealed that either Laurel, Quentin Lance (Paul Blackthorne) or Donna Smoak (Charlotte Ross) may be killed off sometime in the near future.
The photo also showed Oliver and Felicity at the graveyard attending one of the characters' funeral, according to IBTimes.
"Arrow" season 4, episode 16 will air on March 23 at 9 p.m. ET on The CW.
