I don't own Supernatural :)

Prologue:

Ruby remembered a lot of feelings from when she was human. She remembered joy, sadness, sleepiness and a lot more, except one. The one feeling she could not identify to save her life was how she felt with Sam. When she was with Sam, being a demon didn't matter, nor did being tough all the time. She could let her guard down every once in a while and let him take care of things. She was a demon. A demon that was human in so many more ways than others. She remembered it. She remembered trust, and she knew that she could trust one person in the entire world, Sam. She would give her life up for him in a second, she wanted to be with him all of the time. This feeling that she had been struggling to identify, searching her brain for the right word to describe it…

She was in love with Sam Winchester.

"Better think fast…" Ruby mumbled under her breath, more so talking to herself than Sam. Ever since she realized how she felt about him, she had been secretly considering telling him Lilith was the final seal. She knew if she was sure about her feelings than there was no doubt, but if she told him, they would be hunted and she didn't know if Sam would ever forgive her... it was worth it.

"Sam?" She called out. He had just taken out his phone but slipped it back in his pocket when he heard his name.

"I told you Ruby, I need a minute!" He shouted.

"No, you don't! Lilith is the final seal! If you kill her, Lucifer walks free!" She yelled back.

"Wait. Really?" He asked. She nodded. He let out a small laugh.

"Why are you laughing?" She asked, holding back a small smile.

"You didn't tell me before because clearly you want this to happen. Why are you telling me now?" he responded, leaning against the car.

"You wouldn't believe it if I told you." Ruby sighed. Sam quickly grabbed the demon knife and held it against her throat, only a few inches between them.

"Try me." He growled, so unbelievably pissed that anything she said would most likely cause him to slit her throat.

"Because I'm in love with you." she whispered. His eyes softened and he gave her the knife.

"You...you love me?" He asked. She nodded. "How... How long have you felt this way?"

"I started noticing it after that first night..." She trailed off. Sam stood there, motionless for a few minutes.

"I just-I need to..." He choked out and got in the car, driving away. She knew he would come back, so she sat down. She sat, and waited. It took three hours. Ruby was curled up against a tree, asleep and shivering. She didn't wake when Sam pulled up, but she blinked her eyes open when she suddenly got warm. She saw Sam's jacket around her shoulders and Sam sitting in the car on the phone. She got up, put her arms through the sleeves of the large jacket and got in the passenger side of the car. Sam hung up the phone and they sat there in silence for about ten minutes until he spoke up.

"I'm sorry for running off like that. It's a force of habit. Whenever I start to have feelings for a girl... I always leave. I don't want them to get caught up in all the hunter drama. When I was away, I realized something. I don't have to leave to be with you. You're a demon, you're as caught up in this mess as I am! I started noticing it awhile ago... Ruby?" He stopped talking for a second, "I'm in love with you, too." She sat there speechless for a second, then she smiled and Sam leaned in, but she met him in the middle.

"Sam?" She asked.

"Yeah?"

"Let's to find your brother."
