SPOILER WARNING: This article contains major spoilers for "Next of Kin," the latest episode of Arrow.

Love is (back) in the air for Arrow Season 6. In "Next of Kin," the latest episode, Oliver Queen and his on-again, off-again love interest Felicity Smoak got back together, rekindling a romance often referred to as "Olicity" by fans.

Over the course of the episode, Oliver and Felicity reacquainted themselves with one another outside of the team. In one scene, he stopped by her apartment on his break with a Big Belly Burger bag in tow. There, he asked for her advice on dealing with William, who was struggling with an upcoming math exam and rejected all of his advice to relax. She told Oliver that he needed to give William what he needed to help with his math, not permission to relax. As such, Oliver asked if she would come over and tutor William.

Felicity did indeed come by to tutor William. The two worked on math problems together, while cracking a few jokes about Oliver. Oliver didn't seem to mind, though, and playfully joined in with a comment of his own. As it were, Felicity's tutoring helped William out tremendously. Despite being behind in his classes due to his mother's death, he aced the test.

After learning that William had gotten an A, Oliver paid Felicity another visit at her apartment to let her know. This time, he brought a gift with him: a key to his apartment. Felicity was confused when she saw it. According to her, the two had agreed to keep their distance, since William was dealing with a lot of emotional trauma and didn't need another confusing relationship thrown into his life.

However, seeing Felicity tutor William had changed Oliver's mind. He explained that both he and William were better off with Felicity in their lives. After his emotional speech, he went in for a hug, only for Felicity to kiss him instead. Though no words were exchanged, she made it pretty clear that she was willing to give their love another chance.

Oliver and Felicity originally began dating in Season 3. By Season 4, they became engaged. In that same season, the truth about William came out. Because Oliver had kept William a secret from her, Felicity began to doubt their relationship. Then, when Oliver decided to cut William out of his life for his own protection, she broke it off with him because he didn't trust her with these big life decisions. They have worked together on Team Arrow ever since, but hadn't rekindled their romance until this moment.

Starring Stephen Amell as the Emerald Archer, Arrow airs Thursdays at 9pm ET/PT on The CW. The series also stars Emily Bett Rickards, David Ramsey, Willa Holland and more.
