Matchmaking (DeanXReader) part 6.

"What the hell did you just say?" Dean managed to spit out.
"What? I didn't say anything, why did you stop?" you looked genuinely confused.
"You said that you saw – ugh – never mind" Sam tried to say but ended up staring at you, "You really don't remember?" He asked.
"Don't remember what? You're both completely insane, just keep driving, we really need to get out of this town," Dean and Sam stared at each other.
"We'll call Cas; he might know what's wrong with her." Sam whispered.
"There's nothing wrong with me!" you shouted.
"Of course there isn't, you're just as sane as we are" Dean's sarcastic tone was muffled by the roar of the impala's engine.  

You stopped at a crappy motel room, which you understood the Winchesters did a lot of times in their lives.
Dean sat on a chair and started talking, "Castiel, Angel of the lord we need you –"
Castiel appeared before Dean could finish the sentence, "Hello, Dean".
"Cas, uh – we thought you might be able to tell us what's wrong with her".
The angel looked slightly surprised, "Why, what did she do?"
"She said she saw Lucifer in my eyes" Sam interfered.
You looked at them, 'they are all completely insane' you thought.
"Alright, I'll do a quick check" Castiel said, and his hand went towards your chest.
"Whoa there fairy boy, keep your hands to yourself". You took a step back and heard Dean laugh.
"I am not a boy, and definitely not a fairy-"
"The truth I could care less about what you are when your hands are going towards my chest".
This time Sam laughed, you turned to him, "What's so funny, Winchester?"
"Nothing –"
"It's something, you weren't laughing if it was nothing" You said harshly, but he kept smiling.
"You haven't changed a bit," He said.
"Fine, I'll try something else" The angel sighed and pressed two fingers to your forehead.

Images flashed quickly; peaceful cloudy skies, and a man with an awfully familiar voice,
"Say yes, that's all I need from you, say yes and it will all be alright"
"I won't"
"Then I'm sorry, I really am"
The cloudy skies turned blood red, the air tasted like ashes, the angel could feel it, the fire burning your skin.

"It's not possible; it shouldn't be" the angel muttered, looking at his burnt finger tips.
"Cas?" Dean's voice was loud and worried.
"I have to go –"
"Cas, what do we do with her?" Dean looked at you and your panicked expression.
"Kill her".
