Sam took the plunge and told Flash everything that had happened, their theories and what they needed him to do. To his credit Flash didn't panic or immediately discount what Sam said.

"Ghosts are real?"

"Yes."

Flash lowered his head, the earlier laid back attitude he had shown them disappeared. "She can talk to them? Do you think..."

Sam looked at Dean who pursed his lips and looked away. "Flash?" Sam asked

"I, nothing."

Felicity crossed the room and put her hand on Flash's arm, "We don't know if she can reach certain ones, she may just be using the ones that are closest to her."

Flash nodded and looked back up at Sam and Dean, "Let me see if I understand this. You want me to carry her into an old furnace at a shut down iron work, then leave her with you two and Oliver while you decide if she's worth saving or not?"

"That's the plan," Dean said.

"No."

The entire mood of the room shifted as Dean walked into the center of the group and pointed at Flash. "Here's the deal kid," all traces of humor left Dean's voice, everyone in the room stilled as he continued, "Ghosts kill, we've seen them work their way through entire families. They can drown you in a sink, shove you through wood chippers, rip you to shreds, electrocute you and drive cars right over you. This chick gives them an even greater edge because she can get them to work together. You're all damn lucky she hasn't killed anyone yet, but she will. It's just a matter of time."

Flash, to everyone's surprise, didn't back down, "Exactly. She hasn't killed anyone which means she can be talked to. It seems to me that if she's gotten more violent it's because you two shot the ghosts that she thinks are friends."

"We shot the ghosts because they were terrifying a whole office building full of people," Sam reminded him.

"Terrifying, not attacking," Flash said.

"That's it," Dean snarled and took a few steps to stand toe to toe with Flash. "I'm done. Sam and I have been dealing with things like this our entire lives. You know nothing about what opening yourself up to supernatural energy like she is does to a person. It warps you, twists you, you do it long enough, you're past the point of saving. The only way to put vengeful spirits back to rest is digging up the corpses, salting and burning their bones. If she keeps stirring these things up we may end up spending weeks researching each one, tracking down where they're buried and digging them up. You planning to help with that? Well?"

What they could see of Flash's face paled and he took a step back from Dean. "No, I..," he stammered.

"If she unleashes twenty angry spirits on a hospital and kills a bunch of kids, or hell, whole floors of people, you going to explain to the cops and the families what happened?" Dean pressed. "We've seen ghosts do that too."

"I..."

"Dean, that's enough," Sam said.

Dean didn't even turn his head, "No, it's not. It's not nearly enough. I don't know what made you choose to get into this life but this isn't some game where you play dress up and show off your special skills. This is life or death, every damn day. Your choices mean the difference between one person dying or a lot of people dying. Chick controls ghosts, chick is using ghosts as weapons, chick has crossed a line and she has to pay the price. It's that simple." Dean raked his eyes across the rest of the group, no one moved, "Now you guys can sit here and debate philosophy and who's life is worth more all damn night but Sam and I have work to do. Oliver, where's this iron works? Sam and I will go prep it. Then we track this chick down and end this."

"How do you plan to track her down?" Oliver asked, his voice completely calm.

"She's not the only one who can summon ghosts," Dean answered, "I figured we'd ask her friends to relay a message to her."

"Summon a ghost, tell it where we are, have Flash about a mile away, she shows up, he grabs her, sticks her in the furnace and we go from there?" Sam theorized.

"Exactly," Dean replied.

"That would work."

Oliver nodded, "I agree." He grabbed some paper and a pen and wrote down the directions to the iron works. "Here," he handed it to Dean.

Flash looked between Oliver and Dean, "Wait, I haven't agreed to this yet."

"Sam, Dean. Go," Oliver said, "Let me talk to him."

"Fine by me," Dean replied. "Let's go Sam." Dean headed up the stairs, Sam gave Flash an apologetic look and followed Dean.

Oliver waited until the door closed, "I don't remember Dean being that on edge before."

"He wasn't," Dig agreed. "Whatever he's been through lately hasn't been good. He's barely holding on and Sam knows it."

"Damn it! Those two didn't need any more tragedy in their lives. Sorry about that Barry."

Barry pulled back his mask, "Who the hell are those guys? Dean's almost as unstable as the people we put in jail and you want me to help them? No way."

"Technically so am I," Oliver pointed out, "Especially when you first met me, but you helped me. Saved my life."

"Yeah, but he's not even looking for alternatives. He just wants to kill her and be done with it."

Oliver looked around as he gathered his thoughts. He took a seat across from Felicity and gestured for Barry to sit. "Sam and Dean hunt monsters, demons, their father did it as well. He dragged them all across the country and trained them from when they were toddlers on how to hunt the things that we all think don't exist. Demons came here a few years back." Years later a chill still went down his spine when he thought about that day, the sliced up kids, the blood. "You don't know much about the years I was gone but trust me when I tell you that I thought I had seen the depths of evil during that time. I was wrong. I thought when I found out about the Undertaking and who was behind that, including my mom, that was as evil as people could be. Then I saw a demon and realized that all those people I thought were evil weren't even in the same league. The brothers? They barely flinched at the thought of dealing with sixty of them. That's how many were here."

"So they're tough. That doesn't mean they're right or sane."

"It's not about them being tough," Oliver continued, "You can't understand until you go through it but I trust them. If they say this girl has to be killed to stop this, as much as I don't want to take another life, I'll listen. Look, of all the meta humans you've met since the accident, how many have tried to do the right thing?"

Barry looked away, "One, but she gave up and basically killed herself."

"I know you want to try to help people that were affected by what happened, I understand, I do; but remember what I told you when you first asked me what you should do."

"That the lightning chose me so I could help others."

"Exactly." He's so young, so naïve and innocent still. I hope the darkness I feel every day never touches him. Of course, the next thing I am going to say is going to push him that much closer to it. Will it ever end? "I learned how to kill people, I was trained to do it and when I first came back here with my original mission that was the plan. Work my way through a list of bad people and be done with it. Dig showed me another way and I took it. I tried to help a few people that I should have stopped the minute our paths crossed. My own need to save myself blinded me to what the people really were and almost got me killed. People that have some good left in them, in the end they have to save themselves. The brothers have been through more hell than a person should have to deal with in a hundred lifetimes, maybe even a thousand. If they say someone is beyond saving, I trust them."

"But how can they tell. They don't even know her!"

Oliver crossed the room and placed his hand on Barry's shoulder, "The same way Felicity could tell that she could trust you that night you saved my life. Sometimes, you just know. I'll be in that furnace with them, I'll try to talk to her but if she is beyond saving, we have to do what needs to be done. She's too powerful to lock up, even at STAR labs."

Barry's greenish blue eyes gazed up at him, Oliver saw him struggling with what he'd said. How many times have I been in the exact same spot he is now? Wondering if what I am doing is right or even needed? He works with the police, that must make it so much harder because this goes against everything he believes in. Going outside the law to protect others. Ah, the moment of choice. He's going to help, even though it sickens him on some level. The sad thing is, he respects me, God knows why. If he only knew.

"I'll do it. You have to promise me you'll try to save her."

"You have my word." Whatever that's worth these days.
