Back in the bunker, Roy was helping Thea patch up her ribs.

"You okay?" Roy asked as Thea grimaced in pain.

"God, that bitch has a really powerful kick. I think she might have broken one of my ribs." Thea grimaced in pain.

"I assure you that will be the last time you have to face her." Nyssa said as she took the box.

"Yeah. You'll get no complaints from me." Roy said.

"This Athena doesn't seem like a type who will give up easily." John pointed out.

"I intend to take the choice out of her hands by taking Merlyn's map far from here. I know the toll a father can have on a child even long after he's gone. This is my burden, not yours." Nyssa said.

"Take care of each other." she added before heading out.

"Wow. That was a lot easier than I thought it would be." Roy said.

"Ok." Thea said.

"Wait." Roy said.

"No. How are you gonna open it?" Thea asked.

"I'll find someone who can unlock the cipher. My people invented mathematics after all." Nyssa said.

"Yeah. No, no, no. Not this type of mathematics." Alena said.

"Wait." Oliver said.

"Look. You can't- ugh-you can't go out there by yourself, not with Athena's assassins looking for you." Thea said.

"She said that's what she wanted to do, Thea." Roy said.

"Yeah." Oliver agreed.

"No. It's not what I want." Thea said.

"Speedy?" Oliver asked.

"You made it clear once I acquired the map you'd have no interest in your father or the League." Nyssa reminded her.

"And you made it clear that this map, it leads to what, something ancient and powerful. Ok. You cannot- you cannot take this on by yourself." Thea told her.

"Plus we have one of the world's greatest mathematicians right there and the protection that you are gonna need to keep that thing safe while you try to open it." Thea then added.

"I appreciate the gesture. Can you do it?" Nyssa asked Alena.

"Well, in my experience, anything locked can be hacked. Usually by me." Alena said.

"Thea, are you sure about this?" Roy asked.

"Nyssa's right. You did say that you want nothing to do with Malcolm's legacy." Oliver reminded her.

"I know, ok? Look. I can't believe that I am even saying this, but after seeing those assassins, I- this all just became too real." Thea said.

"But Nyssa gave you an out." Roy said.

"I don't know why you don't take it. I don't know how to explain it to you right now, ok? I just-I-I need you to trust me." Thea said, looking at him beggingly.

"All right." Roy agreed.


Nyssa was doing inventory of the armory when she heard Oliver walk up behind her.

"Nyssa." Oliver said.

"Husband." Nyssa said.

"Ha. You gotta stop doing that." Oliver said.

"But that's the fun of it." Nyssa said.

"Thea might want you to stay Doesn't mean you have to." Oliver said.

"Her point about Felicity's utility was well taken." Nyssa argued.

"So was her point about wanting nothing to do with Malcolm." Oliver said.

"It is her life, and she must find her own truth." Nyssa said.

"I think her truth is a new life that she's earned." Oliver insisted.

"She's earned your support for her actions, whatever those may be." Nyssa countered.

"I can understand why she would be conflicted with Malcolm. He was her father. I am not conflicted. He was evil, and Thea should not be charged with righting his wrongs." Oliver said.

"My father was also evil, and I've dedicated the rest of my life to righting his wrongs. From what I understand, you've done the same." Nyssa reminded him, but Oliver wasn't giving up that easily.

"But my father asked me to. With his dying wish, he asked me to." Oliver argued.

"Back on Lian Yu, Merlyn gave up his life for Thea just as your father did for you. I believe Thea owes him the same debt." Nyssa said.

"Well, it is convenient for you to believe that because Thea gets you closer to what you want, so do not pretend that you are selflessly supporting her and never, ever lecture me on what I owe my sister." Oliver growled at her.

"If you think I would use." Nyssa said, insulted, right as Alena interrupted them.

"Nailed it! I nailed it! I got it! Whoo!" Alena said.

"You've unlocked the map?" Nyssa asked.

"No." Alena said.

"Ok. So what do you mean by "nailed it"?" Thea asked.

"Well, I figured out how to unlock the "Hellraiser" cube. I just thought you should do the honors." Alena said to Thea.

"Oh." Thea said.

"You've heard of the Fibonacci sequence, right?" Alena asked, just to have Thea give her a blank look.

"Let's assume not." Thea said.

"The Fibonacci sequence is a mathematical pattern dating back to Pingala's formula in 450 B.C." Alena said.

"Wow." Roy said.

"Yeah. When you said ancient, you were not kidding." Alena said to Nyssa.

"I never kid." Nyssa said.

"The Fibonacci sequence, every number is the sum of the two previous numbers, so finding the two starting ones, that's the tricky part." Alena said.

"So what are the starting numbers?" Laurel asked.

"10 and 13." Nyssa said.

"Is she right?" John asked.

"1013 was the year that the League was founded." Nyssa explained.

"And Malcolm's birthday." Thea added.

"Spooky." Laurel said under her breath.

"Ok. Sit. Try 10. 13. 233659." Nyssa said as she and Alena guided Thea through it until she got it opened.

"Yeah." Thea said as she opened the box and pulled a piece of parchment.

"What does it say?" Oliver asked.

"Nothing." Thea said as she revealed that the parchment was blank.
