The car ride to the Brewery was beyond tense.
Sam didn't want to talk and Elizabeth felt too nervous to go against that.
Grieving Winchesters was not something she felt like messing with.
Even driving, everytime she blinked, she saw a flash of Charlie in that bathtub. Everytime she blinked, more tears threatened to spill.
Rowena and Castiel were talking when they arrived, but as soon as the door closed, they ceased whatever conversation they were having.
"About bloody time!" Rowena huffed.
Castiel rose from his seat at the table in the centre of the room, meeting them at the bottom of the stairs as they descended to the main level.
"Where's Charlie?" He asked.
Elizabeth looked down in shame, causing the Angel to frown in confusion at the Winchester.
Sam simply shook his head. He couldn't bring himself to say the words.
"Oh, no... God." Cas whispered. "I should've gone after her. I- What happened?"
"Me." Sam replied. "The Stynes, um... They caught up with her and, uh... Elizabeth got there just as they turned up but... They- they butchered her, Cas. And Charlie. If 'Liza was Human, she'd... I don't even wanna-" He shook his head, stopping himself before his voice cracked.
"Are you alright?" Cas asked the Vampire.
"Define 'alright...'" She uttered, sinking down against the wall by Charlie's desk.
"Dean's gone after them." Sam added.
"So, he knows." The Angel said gravely.
"Yeah." Sam nodded.
"Well, what now?"
"I'm shutting this down." The Winchester replied. "I promised Dean-"
"Uh, hello? Anybody want to tell me what's going on?" Rowena spoke up from the far side of the room.
"No." The boys snapped.
"What about her?" Cas asked.
"Guess." Sam gritted his teeth as he spoke.
"I'd be happy to kill her, she just called me a fish." The Angel sighed. "What about Dean?"
"We, uh, we should be able to track him." Sam pulled out his phone. "I low-jacked the Impala a few weeks back just in case. Here."
Cas moved forward, looking over the man's shoulder at his phone. Then, the phone went off, signalling an email.
"Is this what I think it is?" Sam asked, walking over to Rowena to show her the phone.
"Oh... That little minx." Rowena smirked.
"What is it?" Elizabeth asked from her spot on the floor.
She got up, walking over to join them.
"She's cracked the code." Rowena replied, showing her the phone.
Elizabeth's eyes lit up, taking the phone for a closer look.
"Does this mean..?"
"Can you read the Book of the Damned with this?" Sam asked the Witch.
"Every last word." Rowena smiled. Sam looked back at Cas, stood behind him. "We can cure the Mark of Cain."
Sam looked as though a small battle was going off in his mind.
"Cas, go find Dean. Make sure he doesn't go too far off the reservation, okay?" He instructed.
"What are you doing?" The Angel asked.
"I'm saving my brother." The Winchester said.
"You told Dean-"
"I know what I told Dean." Sam interrupted the Angel. "Cas, look. I've been the one out there messed up and scared and alone. And Dean-"
"Did whatever he could to save you..." The Angel mumbled, knowing he was right.
"Yes!" Sam exclaimed. "I mean, it's become his thing! I owe him this. I owe him everything! Look, I know he pretends that he can ride the Mark out, but we know the truth, we know what happens if we don't cure him. All three of us know where that road ends." He motioned between himself, the Angel and the Vampire.
"Black eyes and blood." Cas mumbled.
"Yes. Go. Find him, Cas. Keep him safe." Sam instructed. "'Liza, you should probably go with him."
"If I go with him and we face the Stynes, I will not be held responsible for my actions. And I certainly won't put myself in the way of Dean doing the same." Elizabeth held her hands up.
"I don't care if you turn that place into worst bloodbath you've ever seen. Have at it. God knows they deserve it." Sam retorted.
The Vampire looked to Cas with shocked eyes. Neither of them were expecting that out of Sam.
"I'll look out for Dean, you do whatever you have to do." Cas told her.
"Okay..." Elizabeth shrugged, walking off with him in tow.

Castiel unsurprisingly had some questions on the way to Louisiana.
"What happened, Elizabeth?"
"Do we have to talk about it?" She sighed.
"Sam said they butchered you. Did he mean that-"
"Literally? Yeah, pretty much." She mumbled, looking down at her hands in her lap. "There were three of them. Eldon Styne and two of his clan. The two kept me busy whilst Eldon... Did what he did to Charlie. I tried to fight them, I really did. They had me pinned – kept stabbing me all over my body, beating me, the works... I wasn't even sure if I'd even survive it for a second. I... Heard Charlie's screams as- anyway... Eldon walked passed me, making sure I saw how much of Charlie's blood was coated on him. As soon as I saw that, I lost it. What happened with the Angels? That energy blast? It happened again. I took out the two guys, but Eldon had already gone. And, when I saw Charlie... I barely even remember what happened until Sam was force-feeding me blood back at the Bunker."
"That's horrific..." Cas whispered. "I should've been there."
"I'm not sure it would've made much of a difference. It all happened so fast." The Vampire sighed. "God, Dean and I shouldn't have told Eldon what I was. He wouldn't have brought such heavy-hitting back-up."
"I'm sorry you had to go through that, but he couldn't have even known you'd be there."
"I'm sorry I didn't do enough." Elizabeth retorted, leaning her head back against the passenger headrest.
"Don't do that." He said. "Don't beat yourself up. There was nothing more you could've done."
"Yeah..."

By the time they got to the Styne mansion, everybody was already dead.
They walked through the yard, the grass and patio littered with bodies.
In the house, it was worse. There were dozens of them. When they got to a particular room in the basement – an operating room, by the looks of things, Cas decided it was time to call Sam.
"It's me." He said.
"Hey. Did you find him?" Sam asked.
"Not yet. We're at the Styne estate in Louisiana and... Dean was here." Cas replied.
"You sure?"
"I'm sure."
"How bad is it?" Sam sighed.
"There are three bodies down here and more than a dozen upstairs in the main house. He killed-He killed everyone. And brutally."
Cas and Elizabeth heard a light groan from the other side of the line.
"Alright." Sam said. "I'm on my way."
"Don't bother, Sam." Cas told him. "The GPS says he's headed north."
"Where?" Sam frowned.
"Home." Cas replied. "Dean's coming home."
They hung up the phone as Elizabeth released a deep sigh, kicking one of the bodies nonchalantly.
"Want me to zap over to the Bunker and meet him?" She suggested.
"Are you sure you can handle him on your own?" Cas frowned.
"I could take you with me." She shrugged.
Cas thought about it for a moment, finally nodding.
The Vampire walked over to him, grabbing his hand.

They appeared outside the Bunker. The Impala was already there. And then there was a gunshot. The pair looked to each other, making a beeline for the entrance.
The door was on the floor. The place stank of gasoline.
Dean was stood in the archway to the library with a gun in his hand, facing away from them.
Eldon was on the floor in a pool of his own blood.
Dean shot again, this time at a kid who looked no more than eighteen.
"Dean!" Cas called, approaching him whilst Elizabeth hung back. "What have you done?"
"I got rid of a problem." The Winchester retorted. "What the Hell is she doing here?" He pointed with his gun at Elizabeth.
"I'm here to help. Looks like I got here too late..." She sighed.
"Story of your freakin' life recently, don't you think?" Dean sneered, still pointing the gun at her.
Cas moved into the firing line.
"Dean, you don't mean that. It wasn't her fault. She did everything she could." He said.
"Yeah? Well it wasn't enough! Charlie's still dead!" The man yelled, making Elizabeth flinch so hard she had to steady herself on the map table.
"That's enough!" Cas snapped. "This isn't you. This is your grief talking."
"I am my grief." Dean sneered.
The Angel sighed, walking over to the body of the boy on the floor.
"You killed a child." He mumbled.
"I took down a monster." Dean replied, shoving his gun into the back of his jeans. "Because that's what I do. And I will continue to do that until..."
"Until you become the monster." Cas stood back up, addressing him fully.
"You can both leave now." Dean said, turning to walk away.
"No." Castiel told him. "We can't. Because we're you're friends."
Dean stopped and turned back around to face him.
"Really?" He snarled, striding up to him. "Well, let me ask you something; you screw over all your friends?"
"Sam, Elizabeth and I were trying to cure you!" Cas retorted. "We still are!"
"Like Hell."
"We can read the book now." The Angel told him.
"So what?" Dean asked. "So you might find a spell that might take this crap off my arm? And even if you do, what's it gunna cost? 'Cause magic like that does not come free. No, it comes with a price that you pay in blood. So thanks. But I'm good."
He went to turn away from him again, but Castiel grabbed his shoulder.
"No!" He growled. "You're not. Maybe you could fight the Mark for years, maybe centuries like Cain did. But you cannot fight it forever. And when you finally turn – and you will turn, Sam and everyone you know and everyone you love; they could be long dead. Everyone except me and that girl over there who's so desperate to make you better, she was willing to test her immortality for it."
Elizabeth looked down as Dean glanced over at her.
"Back when I was trying to save Charlie? I thought I was going to die. I fought for her and I've been fighting for you ever since I came into your life, Dean. This Mark... And how I failed Charlie, if nothing else, only makes me want to fight harder." She said. "Even if it means facing another apocalypse."
"You see? We're the ones who will have to watch you murder the world if you keep that Mark. So, if there's even a small chance that we can save you? I won't let you walk out of this room." The Angel finished.
"Oh, you think you have a choice." Dean challenged.
"I think the Mark is changing you." Cas replied.
"You're wrong."
"Am I? Because the Dean Winchester I know would never have murdered that kid."
Dean glanced down at the boy's body.
"Yeah, well..." He smirked. "That Dean's always been kind of a dick."
He went to move passed the Angel, but he caught him with a hand on his chest and the uttering of his name.
"I don't wanna have to hurt you." Castiel told him. "Neither of us do."
Dean glared between the two of them.
"I don't think that's gunna be a problem."
He took Cas' arm, bending him into a hunched over position, kneeing him in the face. The two started a punching match. Elizabeth didn't know whether to hang back where she was or try and separate the two.
She took her chance when Dean slammed the Angel to the floor, his body sliding into a pile of books the Stynes had planned on burning.
She Vamp sped at him, but the Mark was taking full effect. He caught her before she could do anything, throwing her out of the library and under the map table with a crash and a wince through gritted teeth.
"Dean." Cas groaned, getting up as the Winchester walked towards the Vampire. "Stop."
Dean stalked back over to him, throwing a punch. Cas caught it and spun him into a bear hug from behind.
Dean head-butted him, making him stagger back a few paces. He grabbed the Angel, kneeing him in the stomach before throwing him into some cabinets in the right corner of the room.
Elizabeth got up, walking over to him as he picked Cas up and repeatedly slammed his head into the wooden furniture.
"Stop it!" She yelled, grabbing his collar and throwing him away from the Angel. "You need to stop. There won't be any coming back from this."
"I don't care." Dean sneered, grabbing the roots of her hair with one hand and her back with the other, tossing her over his shoulder, making her land on the wooden floorboards with a loud thud.
He proceeded to move back over to Castiel, turning him over on the floor.
Cas' Angel blade poked out from the sleeve of his trench coat. The Winchester saw and grabbed it.
"Dean... Please..." Cas begged as the man held the blade above his head.
Dean hesitated... And then plunged the blade into a book next to the Angel's bloodied head, got up and walked away.
"You two and Sam stay the Hell away from me. Next time I won't miss." He growled.
The Vampire slid on her knees to Castiel, cupping the left side of his face.
"It's okay." She breathed as her eyes welled up. "We'll fix this."
Cas took her other hand and shook his head.
"I don't know where we go from here." He whispered.
"Me neither..."
