Oliver arrives and talks about how the most important thing about his graduation was that his parents weren't there. Clark says that he's already mourned his father's death, but Oliver points out that he's dwelling on the past instead of focusing on his future with Lois.

Oliver notes that Clark once convinced him not to go that route, but Clark says that he doesn't belong in either world and he needs to let go of both and take his own path.
Clark goes to the apartment to see Lois, and she shuts him out, saying it's bad luck to see the bride now that the wedding is back on. She tells him that she read his vows and realized she was a fool to give up on the gift they had. Lois slips her vows beneath the door for Clark to read. Before he does, Clark reminds her of her doubts and the fact that her family won't be there, and questions if the stars are aligned in their favor. Lois admits it's a disappointment that her father has been called to a top-secret meeting with the Chief of Staff, but her mother said that her loved ones will always be with her. She asks what Jonathan would say, and Clark says that his father didn't have to say anything because Clark always knew what he was thinking.

He assures Lois that everything is perfect.
They exchange their vows and Oliver gives Lois Clark's ring. Chloe notices that it's not the same ring as earlier when Oliver showed her. She slaps it out of Lois' hand before she can place it on Clark's finger. Oliver's eyes turn black and Clark has Chloe and Lois get everyone out. The possessed Oliver tells Clark to surrender to the darkness and Clark refuses, so Oliver shoves him through a window. Lois goes back in and Oliver grabs her and throws her at the back of the chapel. Clark returns and catches her before she can hit, takes her outside, and tries to appeal to Oliver's true nature. He shoves Oliver back and he drops the ring into the basin, still filled with darkness. They struggle and smash the basin apart, spilling out the ring of gold kryptonite. Oliver picks it up and Clark says that he won't give up on him. He tells Oliver to be a hero and offers his hand to Oliver, saying he believes in him.

Chloe tells him to stay there and be a hero, and they kiss before she leaves.

Jonathan says that he knew Clark would see him when he's ready, and Clark says he made a mistake by trying to leave them behind. Clark is scared because Darkseid knows his weakness, but Jonathan says Clark now isn't the man he was then. He tells Clark that he'll have to let Jor-El guide him now, and that he'll understand that Clark made a mistake in turning his back on him. Martha comes in and tells Clark that it's been coming for a long time, and he's the miracle they prayed for and that the world needs. Jonathan tells Clark that it's time, and Clark thanks them before superspeeding away.
