You had just got done with a hunt and you were now driving back to the bunker. Naturally, Dean was driving, Sam riding shotgun and you and Cas were crammed in the backseat. You weren't exactly complaining because You had a "slight" crush on Cas and it seemed like everybody knew but him. Dean would tease you all the time and threatened to tell him many times but, let's just say there's a reason he slightly limps. You were only afraid he wouldn't return the feelings and telling him would ruin your friendship. So, that being said, you were kinda glad You got to sit next to Cas. As you were driving down the road, You saw a yellow car and immediately,without hesitation, yelled "Mustard!" And punched Cas. Everyone else seemed unfazed as this always happens when your in the car,but Cas looked confused and....hurt? "(Y/N), I am unaware of the reason you have for punching me. Did I anger you?" *facepalm* "no Cas. Don't worry. It's a game." "I don't understand." "Cas, when you see a yellow car you punch somebody and say mustard. it's fun!" After that he went quiet and was intently staring out the window. You figured he was mad at you till he turned around and punched you yelling mustard. Now, your a hunter,you know pain,but dear heaven Cas can punch. Luckily you had just arrived at the bunker. You got out of the car with your arm throbbing and went to your room with out another word. At this point tears were brimming in your eyes. As You looked in the mirror You already saw a huge black and blue bruise. "(Y/N)?"
You whipped around and saw Cas standing in the doorway with a concerned look. "Did I do that?" He asked quietly. You somehow managed to nod your head and as soon as Cas got confirmation he was at your side and the bruise was healed. He then tilted your chin up so your eyes met his sky blue ones and he planted the most gentle, sweet, passionate kiss on your lips saying "I'm so sorry I hurt you." "Its okay Cas. "
"No, it's not I can't stand to see the woman I love..." He muttered the last part but You could still hear him. "Y-you l-l-love me?" You said shakily. "Of course."
You looked in his eyes and said "Well good because I love you too."
You two then spent the rest of the day cuddling and watching Disney movies together. And he never played Mustard again.~G
