"Arrow" Season 4 will address the recent breakup between Oliver Queen (Stephen Amell) and Felicity Smoak (Emily Bett Rickards) when an old villain returns to Star City to target people in love. The CW

The CW’s hit superhero series “Arrow” will return to finish out the remainder of Season 4 on Wednesday after leaving fans on a pretty sad cliffhanger. With the main character’s relationship in trouble, episode 16 will see an old villain return to town to declare war on the citizens of Star City that are in love.

In Season 3 of “Arrow” the character Carrie Cutter was introduced. She quickly became known by her villainous alter-ego Cupid once her obsession with The Green Arrow (Stephen Amell) became so great that she started attacking random citizens in order to draw him out. Oliver stopped her and sent her to jail, where she later joined up with John Diggle (David Ramsey) on a mission with the Arrowverse’s version of the Suicide Squad. Now it seems that Cupid will be back in Star City in the new episode, titled “Broken Hearts,” only this time, she has a very different attitude about love.

According to the episode’s official plot synopsis from the CW, Cupid returns heartbroken and begins targeting couples in Star City on their wedding day. This forces the city’s most prominent couple, former mayoral candidate Oliver Queen and his fiancée Felicity Smoak (Emily Bett Rickards,) to pose as bait in order to sick Team Arrow on the villain. Previously, producer Marc Guggenheim teased the fake wedding sequence coming in episode 16 on Twitter.

This poses a problem for the duo since the previous episode ended with Felicity giving her engagement ring back to Oliver and walking out on him. In episode 15, the character found out that Oliver had been keeping his estranged son a secret from her, at the request of his biological mother. The hero discovered that Samantha and William Clayton were living in Central City in episode 8. When Oliver figured out that William is his son from a tryst he and Samantha had during his billionaire playboy days, she told him that he’d have to keep William’s paternity a secret. Oliver obliged, but when Felicity figured out he was still keeping secrets from her after all this time, she’d had enough. The last time fans saw her, her miraculous spinal implant from Curtis Holt (Echo Kellum) kicked in just in time for her to get out of her wheelchair and walk out of Oliver’s apartment without turning back.

Will it take the danger of Cupid being back in town or the fake wedding bells to make the couple see that they should be together? Or will it simply encourage Felicity that she made the right decision? Fans will just have to wait until “Arrow” returns from its hiatus on Wednesday at 8 p.m. EDT to find out.
