Sam:
You and Sam were sitting in the kitchen doing research for a case you, him, and Dean were working on.
You typed away on you're laptop trying to figure something out. You sighed in frustration.
"What's wrong?" Sam asked you.
"I cant find the location!" You yelled in frustration slamming the laptop shut.
"It's alright." Sam said.
"Sorry for yelling. It's just that if we cant find them, we cant get that girl to safety." You said tears threatening to fall down your face.
"We will find them. I promise." Sam told you.
"Are you sure?" You asked him.
"Yeah," sam said putting his hand on your leg. "I love you."
You smiled. "I love you too nerd." You said kissing his cheek.Dean:
The two of you were at the bar where the two of you had met so many years ago. At the time you had no where to go since your boyfriend/girlfriend had kicked you out. So Sam and Dean had offered you to stay with them. At first you said no but Dean insisted on it and you finally gave in.
Dean had ordered you and himself each a beer.
You were drinking your beer when you smiled, "I love you." You told Dean
"I love you too sweetheart" Dean said.Castiel:
The two of you were sitting in your room watching a movie.
The two of you were watching a romantic movie when the characters on the screen had told each other that they loved one another.Castiel looked over at you. "What does love mean?" Cas asked you.
"When you would do anything for someone, when them just being around makes you happy, when you realize home isnt a place, it's a person, you always want to be around them" you said.Castiel smiled and put his hand on your cheek. "Then, I love you y/n Winchester." Castiel said kissing you.
"I love you too honey." You said smiling.
