Balthazar
You and Balthazar were in a Museum stealing things until the cops showed up. Balthazar zapped out without you. Oh boy were you pissed. The cops arrested you and shoved you in the back of the cop car. You arrived at the police station and were placed in a cell. A few minutes later you were allowed a phone call. You weren't going to call Balthazar because the ass left you there by yourself. So you called Dean to come get you. Dean arrived 15 minutes later.
Dean: What the hell happened?
You: Balthazar and I were in a museum stealing things and the cops showed up and he left without me.
Dean: Damn angels
You: You're telling me!
Dean and you headed to the impala then headed home. You walked into the house still raged because you were left alone. Cas walked up to you.
Cas: I heard about your arrest
You: Yeah and Balthazar left me there!
Cas: Seriously? He was supposed to watch you
You: Yeah well he didn't.
You grabbed a beer from the fridge opening it and taking a sip. Balthazar showed up a few minutes later. You threw the bottle at him watching him duck as it shattered on the wall behind him.
Balthazar: Hey babe, calm down
You: Screw you. You left me there by myself!
Balthazar: I'm sorry angel. I love you
You: Yeah whatever I love you too jackass, but you ever do that again I will smite you myself and I'm serious

John (WARNING Suicidal)
It wasn't easy being the girlfriend of John Winchester and hunting and watching the two boys. You had to do this though, for Mary. You promised her you would always look after her family no matter what. Recently, well 2 weeks to be precise, you were depressed. Your family and friends were all dead and John hasn't been home in the 2 weeks. Even when he was home he barely talked to you, he was always focused on research and the boys were at Bobby's. You knew what you needed to do. You walked into the bathroom not even bothering to close the door. Nobody would find you until it was too late. You took your knife dragging it across your wrists then stabbing yourself in the stomach. You fell to the ground faintly hearing someone screaming NO. The last thing you remember was someone carrying you then it went black. When you woke up you were in a hospital room. You looked to your right seeing John with his hands buried in his hands crying. You grabbed his hand.
John: Oh my God your awake.
You: Yeah I guess I am
John: Why baby why did you do it
You: My family and friends are all dead and you never talked to me when you were home. I didn't think anybody would care
John: Babe I'm so sorry I promise I will pay more attention to you and help you. I love you
He leaned forward kissing your forehead.
You: I love you too John

Adam
You and Adam were drinking except he was drunk. You were dying of laughter at the stuff he was saying. You could hold your liquor be he clearly could not.
Adam: You're so prettyyyyyyyyy and your hair is all whooshhhhhh
You broke out laughing.
Adam: I love you
He passed out leaving you smiling. He woke up a few hours later sober this time.
Adam: Hey, that's the worst hangover ever
You: Obviously. You told me you loved me while you were drunk
Adam's face fell.
You: I love you too my little weirdo

Cain
You decided to visit your boyfriend considering it's been a few weeks since you last seen him. You got in your car driving to Cain's house. You walked in.
You: Cain I'm here
You walked to the kitchen seeing him sitting at the table with a beer in front of him. He was staring off into space.
You: Cain babe I'm here
Cain stood up walking over to you grabbing you tightly pulling you into a hug.
Cain: I missed you so much
You: I missed you too my love
He started crying. You caught him before his knees gave out. You lowered yourselves to the floor sitting on his lap holding him.
You: What's wrong love?
Cain: Promise me you won't leave me. I love you and I hate being by myself
You: I promise you I won't leave. I love you too. I hate the lonely feeling too
You two sat there for a while in silence just holding each other.

Bobby
The boys had left for a hunt leaving you and Bobby by yourselves. Bobby was sitting at the table you were rubbing his shoulders. You had turned on some music trying to relax. You gently grabbed his hand pulling him up. You placed his hand on your waist and placing one hand on his shoulder putting the other one in his other hand. You placed your cheek against his shoulder burying your face in his neck. Both of you just dancing.
Bobby: I'm glad I got a break. I haven't been this happy since Karen
You: You deserve a break and I'm sure she's happy your happy
Bobby let go of your waist spinning you around then pulled you back against him.
Bobby: I haven't ever wanted to say this since Karen but I love you
You: I love you too Bobby
You two smiled at each other just dancing the night away and when you both got tired you fell asleep on the couch on his chest with smiles on your faces.

Benny
You were tied up of course by vampires. They were trying to get back at Benny. Of course they messed with the wrong girl and vampire boyfriend. You broke the ropes standing up and smirking at the vampires.
You: Game on bitches
You pulled the machete from under your shirt cutting at least five heads off. Benny showed up killing the rest smirking at your work.
Benny: Glad I have you for a girlfriend
You: Yep be glad
You patted his cheek laughing. His arm slid around your waist both of you walking out together.
Benny: Have I told you how much I love you?
You: Nope but I love you too
