After the failed raid on the warehouse, other then picking up Sara, the team returned to Argus, where Sara was being examined by doctors.

"I'm fine. Alex is the one who needs your attention." Sara said to the doctors when they finally cleared her.

"Sara, who did this?" Oliver asked.

"It was Slade Ollie." Sara said.

"That's impossible." Oliver said, though he knew it was very possible.

"Yeah, I thought so to. But I guess he's harder to kill then we thought and that's saying something." Sara said.

"Wait, who are you talking about?" John asked, since while Oliver had told Laurel about Slade, it had never come up with the others.

"Slade Wilson. I met him my first year on the island. He taught me a lot of what I know. He was my best friend." Oliver said.

"What happened to him?" Thea asked.

"I put an arrow in his eye." Oliver said bluntly, much to their shock.

"Ok, if that's how you treat your friends." Roy said.

"It's not like that. I met Slade a year after Oliver did and to save his life, we had to inject him with this drug called mirakuru. It saved his life from what otherwise would have been critical injuries, but it caused him to go insane. The woman Slade loved was killed on the island and due to his mental instability, Oliver and I lied to him about how it truly happened." Sara said.

"Which was a mistake, since he eventually found out." Oliver said and Sara nodded.

"What happened?" Thea asked.

"This man, Anthony Ivo, he made me choose between Sara or the woman Slade loved, Shado. He shot shadow and then when Slade found out, he made it sound like I chose Sara over Shado. Slade has blamed me for her death ever since and hates me with a passion. The last time I saw him we were on a sinking ship in a fight that ended with me putting an arrow in his eye. I was sure he was dead." Oliver said.

"Sounds like a swell guy, but why did he kidnap Sara if you're the one he has an axe grind with?" Laurel asked.

"Actually, Slade hates me almost as much as he hates Oliver. He blames me for luring Ivo to our location and making it possible for him to kill Shado." Sara explained and Laurel sighed.

"Any other enemies from your past we should know about?" Thea asked.

"The rest of them really are either dead or rotting in military prison." Oliver assured them.

"Good. But anyways, what do we about Slade?" Laurel asked, but before Oliver could respond, Sara rushed over to where Alex was being treated.

"Is she gonna be okay?" Sara asked.

"Slade injected her with some kind of drug that currently has her unconscious. We don't know when or if she'll wake up." Kara said and Sara could feel her tears threatening to drop as she took Alex's hand in her own.

"Come on Alex, stay with me. I can't lose you." Sara softly begged her.

"I think I know a way we can not only stop Slade, but also help Alex." Oliver said.

"How?" Kara asked.

"Ivo developed a cure for the mirakuru by reverse engineering it." Oliver said.

"But it was destroyed." Sara said.

"Maybe, but it sounds like Alex has the mirakuru in her now. If you take a sample of her blood, you can separate the mirakuru from it and use it to reverse engineer the cure. We can then save Alex and also weaponize it against Slade." Oliver said, though he knew that Cisco was already working on the cure.

"I can take a sample back to my team at Star Labs. They shouldn't have much else to do right now, which means they'll have more time to devote to the cure." Kara said, since Cisco had already told her and Barry that he was working on the cure for Oliver.

"Do it. I don't care who does it, as long as they save her." Sara said as she placed her other hand on Alex's still one.

"Sara, I promise, we will save her. But I need to get back to Central City. Call me if there are any changes." Kara said.

"At least wait until we get you a sample of Alex's blood." Lyla said and Kara nodded.

"I promise, the moment that cure is done, I am going to fly right back out here to give it to her. Just make sure she holds on until then." Kara said and Sara nodded.

"I will. I'm not letting her go." Sara said.
