The stairway seemed taller on the way up. She joined the group, knowing she was about to help deceive them, knowing she was going to help Dean. What choice did she have? Her loyalty was to him first. Bobby was still stationed in his wheelchair next to Adam, while Cas and Sam were talking in the kitchen. They stopped when they saw her.

"Did you change his mind?" Cas asked.

She tucked her hands into her pockets and shook her head, unable to meet his eyes.

"And you didn't tell him." He muttered, the anger returning to his voice. "Don't you think, that it might affect his decision to hand himself over to the angels for servitude?"

Sam looked between them. "What's he talking about?"

"Nothing." She snapped.

Cas tilted his head and tried to reign in the fury burning inside of him. He expected so much more from them. "Kayla. He has a right to know, before he does this."

"Don't you say it. Castiel, please." Her eyes glanced to Sam and she saw all the questions flashing through his mind. "Just stop talking."

"If you don't tell him, now, I will." He warned her, and Cas certainly didn't bluff.

"Fine." Her answer came out in an unexpected quip. "Do what you have to."

He looked confused by her sudden surrender, but he wasn't going to sit back and let this continue. "Have it your way." Cas went to the staircase and Kayla bit her lip.

Sam's mind was searching for the right answer and he grasped to add everything up. Kayla was always the first to go to Cas, whether it be for help or to help him. She'd looked at him differently since he saved her and they'd gotten close, really close these last few months. He was so relentless about protecting her, physically and mentally and she wasn't even a key player in the apocalypse. He'd always thought it was for Dean's sake, but that night before they met Lucifer…Christ.

Had he really thought so highly of her that he'd completely missed this? He has a right to know. Kayla spent more time alone with Cas than she did with him lately, why hadn't he ever suspected? She had been in awe of him since the day he showed up. If it were true, why tell him now? If Dean knew there was something between them, maybe they figure he won't leave them together, or he'll change his mind about helping the angels altogether in retaliation. Either way, Dean was going to lose his mind.

"Kayla."

Before he could question her, Castiel screamed from the basement and it echoed through the halls. A light from the stairs briefly shone into the hallway but instantly died down. Sam looked at Kayla and saw the recognition in her eyes. The expression that told him exactly what happened.

"You didn't." He took off down the stairs. "Dean!"

She knew he was too late, Dean would be out of there by now and out of eyesight. He knew his brother would come running. Sam came slowly back up the stairs and stopped in front of her.

"Michael said…"

"Angels lie! Damn it Kayla," he walked towards her with balled fists. "How could you let him do this?" There were tears in his eyes as he yelled at her. "Of all people, you should care about what happens to him!"

"What if it's the best choice? What if it's the right thing to do and we screw it up, again?"

"How can letting millions of people die be the right choice?" He stopped and looked at her. "He gave it to you didn't he?"

"What?"

"The ring!" He pulled her hand out from where it was tucked under her arm and saw the engagement ring on her finger. "God damn it Dean."

"You knew he had it?"

"Yeah." He shook his head and stepped away from her. "I was with him when he got it. I can't believe he used it to distract you."

She shook her head. "That's not true Sam, he'll be okay."

"What if he isn't?" He grimaced. "What if he is? He lets Michael win, and they have their big battle and the angels win. Millions of people die in the process but that's alright, as long as you two get to live happily ever after?"

It was a low hit, and she supposed he wasn't all that unjustified. Still, she couldn't help but remember their time in the future, the future where Dean didn't say yes. "Half the planet is better than the whole planet."

He couldn't argue with that, because no one knew at this point who was right.

"Where's Cas?" Bobby rolled his chair over.

"Blown to Oz." He snatched his jacket off a chair and pulled it on, there was fire in his eyes as he looked at Kayla. "Help him watch Adam, I'm going after Dean. Can you handle that or should I just throw you in the panic room?"

"No, we're on the same page with him." She returned.

"We'd better be."

She opened her mouth to shoot something back at him, but quickly changed her mind. Tension was high and there was no need to threaten each other back and forth. What's done was done. "Good luck."

He ran out the door. Now it was Bobby giving her the look and she sighed quietly.

"Save it Bobby."
