TW: Nothing in this chapter!
A/N: This is a pretty short chapter, but I wanted to split this chapter, and the next chapter up. Also, this is part of @kas-not-cas 2.5K Writing Challenge! Honestly, whenever I do challenges, I prefer writing a separate fic that’s not a part of a series, but it just went to so well with this chapter that I couldn’t help myself! I know I got your permission to use the Prompt in a series, but if you want me to write another oneshot separate, I can totes do that!
Prompt: “I’ve lost count of the promises you’ve broken.”
When Dean woke up the next day, he slipped carefully out of bed, trying not to wake the sleeping girl so he could make breakfast. As he headed towards the kitchen, he passed by the library, seeing Sam with his laptop.
“What are you doing?” the older Winchester asked.
“Tracking down the alpha vampire,” Sam responded, glancing at his older brother briefly before going back to his computer. “We’ve got less than three weeks to find him, and kill him.”
Dean nodded, knowing they couldn’t push back finding the monster any longer. As much as he wanted to focus on making sure Y/N was getting better, they needed to focus on killing the vampire first. He made his way to the kitchen to prepare himself a cup of coffee, and started boiling the water for Y/N’s tea when a blood-curling scream stopped his heart. Dean quickly ran to his room, meeting Sam in the hallway. It didn’t matter than he was unarmed. He would fight tooth and nail, with his bare hands, with whatever decided to come to his home, and attack his loved ones.
The boys nearly broke the door down when they crashed into the room, seeing Y/N curled against the headboard, and Castiel standing at the edge of the bed with his head titled to the side. She was sobbing, and hyperventilating while Castiel was calmly trying to explain who he was.
