Laurel was looking around the Waverider in astonishment. Sara was getting the jump ship ready to go. "Are sure you want to do this?" asked Sara to her sister's doppelganger.
"I am" Laurel replied. "I have lost everyone I care about in this life and I am ready to go home to the good lord".
"I respect you because this is not a decision I would make" Sara acknowledged. "Thank you for your bravery".
"I won't need it anymore soon enough" Laurel joked and she and Sara shared a small, awkward smile. Sara then walked over to Laurel and gave Laurel a small and unexpected hug.
"The jump ship is ready," Sara told Laurel and the two of them climbed in. "There some side effects to time travel" Sara informed as she clicked the big button that said "JUMP".
When the sisters landed back in Star City on the morning of April 6th, 2016, Laurel felt queasy. Sara quickly made over Laurel so she donned the identical look to earth 1 Laurel. Then the girls went to Laurel's apartment and Sara knocked on the door. Laurel opened the door when she saw Sara through the peephole but was surprised at the sight of another woman who looked exactly like herself. Earth 2 Laurel released a cry that knocked Laurel down. Sara inserted a tranq dart into a vein in Laurel's neck.
Laurel awoke on the Waverider and she remembered everything. "Sara?" she called loudly and Sara entered and looked at her older sister who was behind the glass of the Waverider's holding cell. "Sara? What the hell? Is this the Waverider? Why? God damn, Sara. The team will worry about me!" Laurel scolded. "And who was that woman? She looked exactly like me..."
"Look Laurel" Sara began "you won't understand this or like it, but I am from the future and in this future you are dead. I know this is a lot to take in but that woman is your doppelganger from an alternate earth. She is a reformed criminal and she is depressed and she feels that you deserve to live instead of her. On this timeline, Damien Dahrk kills you tonight, but this time he'll kill her. She is going to be a hero and make a hero's sacrifice. She has lost everything, but Laurel, you still have a chance".
Laurel tipped her head down. "Sara, how could you agree to another humans life being sacrificed for mine?" Laurel complained.
"Because I love you, sister, always and forever. So get comfortable" Sara responded.
Team Arrow was facing Damien Dahrk in Iron Heights when Damien began to come close to Laurel and grow more threatening. Alarm bells went off in Oliver's head. "Not Laurel, anyone but Laurel". His thoughts were racing as he knocked an arrow into his bow and released it. The arrow went hurdling towards Damien but he caught it in his hand.
Damien smiled and looked into Laurel's eyes. "This will let your daddy know that I always keep my promises," he told her and then pushed Oliver's arrow through Laurel's chest right under her heart.
"NO!" Oliver screamed. He ran to Laurel and scooped her up bridal-style in his arms. Laurel's world went dark.
In the hospital, Thea, John, Felicity, and Oliver were in her room when she opened her eyes. "Hey" she whispered.
"Hey, yourself" Thea replied.
"Did Damien get-get away?" Laurel asked, hoarsely.
"Don't you worry about Damien" Felicity said and put her comforting hand on Laurel's cold skin. Laurel smiled slightly, it was so good to see Felicity.
"Tonight was going to be my last night as The Black Canary" Laurel confessed, following a script that Sara was able to give her based on Gideon's database. "But I realized that if I make it through this, there is no way that that will be possible because I love you guys so much".
"We love you" Thea assured.
"We love you," Felicity said too.
"We love you" John echoed.
"I love you," Oliver said and Laurel smiled at hearing him say that.
Laurel encouraged the group to get some rest, but Oliver chose to stay with Laurel. She wasn't sure how much time she would have. "Ollie, I have to tell you something".
"Yeah, what is it?" Oliver asked in a comforting tone.
"Laurel- I mean- your Laurel is safe. She is with Sara on the Waverider" Laurel confessed.
"What do you mean?" Oliver asked, standing up straight. "Who are you?"
"I am Laurel Lance from a different earth. Also, I am from the future and we were married. I came back to save Laurel's life because she was supposed to die tonight. Listen to me, you two are meant to be together, she is the love of your life, Ollie. I felt terrible standing in the way of that" Laurel confessed and Oliver nodded in agreement.
"Where is Laurel? I have to see her" Oliver begged.
"When I die, Sara will get a signal and come to get you with the Waverider's jump ship. You will see her then". Oliver nodded.
A few minutes later, Laurel began to sieze and Oliver panicked and called for Dr. Schwartz. Dr. Schwartz did her best to revive Laurel but then sighed and announced "Time of death: 11:59".
Oliver rushed out to meet Quentin. Quentin saw Oliver. "Is she okay? Tell me my baby is okay!" Quentin nearly shouted.
Oliver smiled. "Quentin, she is okay. She is safe with Sara on the Waverider. The person who was stabbed tonight was not our Laurel. It was Laurel from another earth. Barry would be better at explaining it then I would be. But we have to go now" Oliver grabbed Quentin by the arm and headed to the rendezvous point that Sara had texted him.
When Quentin and Oliver got to the rooftop Sara had chosen, the jump ship shortly became visible. It landed and Sara stepped out and ran into her father's arms. "Daddy!" she shouted. "I missed you".
Quentin kissed Sara's head. "I missed you, Sara" Quentin replied. Quentin did not know that the last time Sara saw him, he had been lying dead in a hospital bed.
Laurel stepped out next and Oliver walked forward to her and he pulled her into his arms and kissed her lips. She looked at him with her eyes twinkling in the moonlight. "Laurel, I have been a fool" Oliver admitted. "I'm sorry for everything. Please forgive me and be my wife?"
Laurel nodded. "Yes," she replied.
Sara hugged her sister. "Let's get back to the future everyone," she said and the four of them climbed into the jump ship and Sara reprogramed it.
