He hadn't believed Sam. He really thought that chick doctor was the siren when in actuality, it was Nick Monroe. Why hadn't he seen it? The guy knew cars, he knew the good rock, he trusted him; he was way too cool to be a fed. Now it was too late…
"I should be your little brother."
Dean looked at Agent Monroe.
"Sam, you can't trust him." He shook his head. "Not like you can trust me."
He was right. He couldn't trust Sam. Not with all this Ruby crap and the lying and psychic powers and trying to sleep with Kayla…
"In fact, I really feel like you should get him out of the way so that we can be brothers, forever."
"Yeah." Dean nodded. "Yeah you're right."
"And you know Kayla, she's cool and everything, but you know she cares about him. You know she won't let you hurt him and won't let us be brothers. You're gonna have to take care of her too."
He nodded again. "Okay."
At the hotel
Kayla looked at the clock; hours had gone by and she was starting to worry. She'd gotten a call from Dean saying he and Monroe were scouting for Dr. Roberts and hadn't heard from him or Sam since. As she looked back she gasped, nearly coming out of her skin as she saw the man standing by the door.
Castiel stepped forward, his expression calm. "I didn't mean to startle you."
"Well ya failed." She paused, looking at him. "You're not here to see Dean."
"We need to leave."
"Son of a…" she sighed and grabbed her shoes. "That slutty bitch got to him didn't she?"
"Not a woman for him…a little brother. One that's honest with him, likes old cars and old rock, one that doesn't get phone calls from demons…"
"Of course, Christ Dean." She shook her head. "Where are we going?"
"You should be somewhere safe, he's looking for you and Sam."
"Well, I guess anywhere but here would be a good start." She smiled lightly. "Thanks Cas, for coming to help."
He looked away from her then and pulled the door open. His eyes showed his guilt; he still regretted not paying more attention to them when Alastair had come. He still felt like he had failed.
She hid her smile and tried not to dote on him, since it made him uncomfortable. "It wasn't your fault you know."
He briefly made eye contact before following her into the hall. "Bobby is on his way to help, you should stay clear of them before he gets here. They can handle it."
"But if Dean is infected then I could get some blood from him to use on the siren."
Castiel was shaking his head through her reasoning. "The siren has told him to kill you, you shouldn't be near him."
"I know but…"
"Kayla." He stated, a little more firmly now. "Sam and Bobby can take care of Dean. Let me protect you."
How could she not smile at that? "Alright Cas, whatever you say."
