This story is tied to "Unforgivable". For those who haven't read it, it's a mega crossover story, mostly focusing on the Flash. If you don't want to read it, that's okay me. Besides, it's a 70-chapter story. Although, it would help understand what's going on in this story.
This story follows the final episodes of Arrow Season 5, but with a few changes.
By the way, I watched the season finale of Arrow, and it was truly an explosive finish, pun intended, to a truly fantastic season. I'm not saying it's better than Seasons 1 and 2 (they'll always be the best), but S5 comes pretty close. Between the return of Deathstroke (especially being portrayed by Manu Bennett instead of a stuntman), the al Ghul sister duel, Black Siren vs. New Black Canary, and the emotional flashback phone call between Oliver and his mom, it's certainly one of the best Arrow episodes I've seen. The cliffhanger scares me, though.
Leave a review after reading, please. Feedback is always appreciated.
After helping the Flash defeat Killer Frost, Team Arrow returned to their mission of stopping Adrian Chase, a.k.a. Prometheus. Star City was still under rebuilding, but with nearly every citizen lending a hand, including children, the process was going faster than expected. Quentin Lance comes back to the mayor's office after rehab. Roy offered to step down as deputy mayor and let Quentin take back the position, but he declined. He, instead, offered to be the deputy mayor's assistant, helping Roy with his job.
After the fiasco involving Felicity and her alliance with Helix, Chase traps Oliver and Felicity in the rebuilt Arrow Cave with an EMP blast. They were rescued, but while they were trapped, Chase found Oliver's son, William, and kidnapped him.
Team Arrow then faces a big problem when 36 criminals prosecuted by Adrian Chase have been released, and one of them is Derek Sampson, who was working with Chase to release Justin Claybourne's weaponized tuberculosis all over Star City.
Meanwhile, Chase sends Oliver a corpse. It was a councilman named Henry Goodwin who was "murdered" by his father, Robert Queen, who then covered it up. Oliver and Thea met with Justin Claybourne's lawyer and learned something they could use against Chase.
After Felicity found where Sampson at Robert Queen Applied Sciences, Team Arrow suit up and head to the location. Wild Dog and Arsenal arrived early and found Chase on the rooftop of the building. They were told to wait for the rest. Green Arrow, Speedy, Spartan, and Mr. Terrific head upstairs, only to run into Prometheus. Green Arrow engages Prometheus while the others help the rest with Sampson. Sampson nearly killed Wild Dog, but was blown away by an explosive arrow, courtesy of Arsenal.
Green Arrow reveals to Prometheus that his father never loved him. He was going to disown Chase because he was insane. Disillusioned, Prometheus was ready to accept death, but Green Arrow refuses to kill and, instead, detains him in A.R.G.U.S.
While Team Arrow celebrates their victory, Rene mysteriously disappears without a trace. He was supposed to be at a hearing to get his daughter, Zoe, back, but he didn't show up, much to Zoe's despair and Quentin's disappointment.
After a night at the office, Oliver returns to the loft. When he showed up, he can see that the door was open. He slowly opens the door and stays alert, thinking someone might be trying to ambush him. Someone comes in from his right. Oliver grabs the man's arm and flips him to the ground. He was about to punch him in the face, until he saw who it was. It was Curtis.
The lights open, revealing birthday decorations.
"Surprise!" said everyone, only to drop their smiles when they saw what Oliver did to Curtis.
"Uh, happy birthday," said Curtis to Oliver. "Everything hurts. Everything hurts."
While Curtis gets an ice pack for his neck, Oliver starts blowing out the candles on his cake. Felicity bought the cake from Lord Mesa Bakery, which explains the Green Arrow fan art on the cake. She also explained that she ordered the cake for a six-year-old because she wasn't sure she could buy a Green Arrow cake for a grown man.
The doorbell rings. Thea answers it and sees Quentin carrying two gift boxes.
"I'm late, aren't I?" guessed Quentin.
"That's okay. You didn't must much. Just Oliver flipping Curtis over his shoulder," said Thea.
"I told a surprise party wasn't a good idea," said Quentin.
The two discussed about Rene. According Quentin, he's still missing. He found two day-old newspapers at his house. They decided to discuss this further later and enjoy the party. Felicity poured glasses of champagne and club soda for everyone. After discussing about what they each wanted to do during the summer, Felicity decided it was time for Oliver to open his gifts.
Oliver picked up a small box on top of Quentin's gift.
"There's no name here," noticed Oliver.
"Yeah, but it was addressed to you," said Quentin.
"Should I call the bomb squad?" joked Thea.
Oliver opens the box and finds a heart-shaped rock and a letter inside.
"What does it say?" asked Thea. "Does it say who it's from?"
Oliver reads the letter. "Dear Oliver, I know this is probably the lamest birthday gift I could give you, but it was the best I could think of. I just want to let you know that I'm alright and I never stopped thinking about you. Every time I sleep at night, I see your face. When I wake up in the morning, you're the first I think about. I wish I could be with you today, but I still hope this gift will make up for my absence. I love you. P.S. Happy Birthday."
"Sounds like you've got a secret admirer," said Quentin. "Is this another person from your past?"
The rest exchanged looks, knowing who exactly the rock and the letter came from. Even Oliver knew. He picks up the rock and sees the arrow symbol carved on it. He smiles.
When Roy didn't show up for the party, Curtis offered to check on in. On his way, he talked with Thea on the phone.
"Are you sure two don't want to get back together?" asked Curtis.
"He has a girlfriend in Hub City," said Thea.
"He said he was seeing someone. He didn't exactly say he had a girlfriend," said Curtis.
"Still doesn't give me the right to just steal him," said Thea.
"But you two clearly still love each other," said Curtis.
"Don't make me flip you like Oliver did," threatened Thea.
Curtis arrives at Roy's apartment, only to see that some of the glass on the door has been shattered.
"Uh oh," said Curtis.
"Uh oh what?" asked Thea.
"I think he was robbed," said Curtis.
"Do you need backup?" asked Thea.
"Yeah, probably, but I'm here now, so I gonna make sure he's okay," said Curtis.
Curtis opens the door slowly and looks inside. The place was a mess. A fight clearly broke out.
"Hello? Roy?" called Curtis. "If there's someone in here, you should know that I know martial arts."
Curtis sees something, but before he can tell Thea, someone hit him behind the head, knocking him out and causing him to drop his phone. Someone started dragging the body away. Thea repeatedly calls out Curtis' name, but he didn't respond, causing her to worry.
Meanwhile, in the snowy mountains of Russia, Laurel Lance, dressed up as the Black Arrow, has found Talia al Ghul's monastery. She kicks the door open and enters.
"Talia?!" shouted Laurel.
No one showed up. Laurel takes out an arrow and keeps her bow up just in case of an ambush. She searched the entire monastery, but there was no one there. All she found were lit candles and a room full of weapons. If Talia and her students weren't here, then there was only one place they could be.
"Oliver," muttered Laurel.
Back at Roy's apartment, Oliver and Diggle showed up, but found nobody. All they found was a messy apartment and Curtis' phone on the floor.
"I found Curtis' phone, but no Roy or Curtis," said Oliver.
"Okay, well, if Roy and Curtis are missing, then I can guess Rene didn't skip out on his daughter," said Felicity.
"Whoever did this must be good," said Diggle.
"I know who's doing this. It's Chase," said Oliver. "He's picking us off one by one."
"Hate to state the obvious, but Chase is currently under surveillance 24/7 in an impenetrable glass box," reminded Felicity. "There's no way he got out to do this."
"Well, he had to have help," said Oliver.
"I hate to say this, but what if this was Chase's plan all along?" wondered Diggle. "Get himself caught, lull us to sleep."
"Yeah, well, consider me officially woke," said Felicity. "Okay, Chase has worked with Caitlin before, but she's dead, and there is no way Evelyn is doing this all by herself."
Oliver found a flechette piercing a book. It had a familiar design.
"Isn't that League?" asked Diggle, recognizing the design.
"It's Talia al Ghul," said Oliver. "Contact Thea and Lance. We need to get them to some place secure."
"There's an A.R.G.U.S. safe house across town we can use," said Diggle.
"Okay, you get them there and we'll meet at the bunker," said Oliver.
Oliver leaves the apartment.
"Where are you going?" asked Diggle.
"It's time to talk to Chase," said Oliver.
Later that night, Oliver shows up at Chase's prison in A.R.G.U.S.
"Where are they?" he asked. "Adrian, where are they?!"
"Who?" asked Chase, pretending to be oblivious.
"You know damn well..."
"You know damn well who!" shouted Chase, mimicking Oliver's tone, knowing that he was going to say that. "You're right. I do know. Just like I know your every move, while it seems like you know none of mine."
"Tell me where they are," demanded Oliver.
"Or what? We've already established that you think you won't kill me," said Chase. "Kinda weakens your leverage."
"I'm gonna find them and I'm gonna get them back," said Oliver.
Knowing he's not gonna get anything out of Chase, Oliver leaves A.R.G.U.S.
"Is that what you came to tell me or are you just wasting time?" asked Chase. "See ya later."
Chase just chills out in his cell, waiting for his plan to come to fruition, laughing behind Oliver's back.
Like I said, the same plot but a few changes. If you have any questions, you can either ask me.
