Finally, the last war has ended. No more demons.
The Angels had their own war up in Heaven and no matter how much Dean hated it, Cas had to go. It's been years, four to be exact, and right now, Sam and Dean were helping a poor victim of the last demon's wrath when a voice in the distance called "Dean!", both brothers ignored it. Sam because he didn't hear, and Dean because he's been hallucinating Cas calling for him every day since he left, it wasn't easy with him gone, considering they both realized their feelings for each other when Sam pushed them both under the mistletoe the year after The Fall during Cas' first Christmas. As they were patching up the young boy's arm, the voice called again, and this time, Sam heard. "Dean?" Sam asked, looking in the direction of the voice. "mm?" was his brother's response. When Sam didn't answer, he looked up at his brother's face and noticed tears in his eyes. "Sammy? What's wrong?" "Take a look for yourself." was his only reply, as he stood up and started packing the first aid kit. Dean stood up and in the distance he saw a trench coated man limping slowly in their direction. He immediately knew it was Cas. Dean's eyes filled with unshed tears as he held back the urge to run. "Well, what are you waiting for? Go!" Sam insisted, but Dean didn't need to hear it twice, he stared walking. Slowly picking up his pace until he was running faster than he has ever ran in his entire life. It was a sight to see, really, Castiel, Angel of the Lord, running. but that didn't matter because Cas was back! All those lonely nights without his Angel, and now he finally has him back, heart pounding, mind racing, legs numbing, he was almost there, just a few more-
he was shoved to the ground, the wind knocked out of his lungs. It took a few minutes to catch his breath, but when he did, he realized why he fell.
On top of him, was a trench coated angel with black hair and bright blue eyes. "Cas!" Dean exclaimed, bringing him into a closer hug. He rolled over onto his side and sat up, Cas never letting go, "I've missed you so much, Dean." Cas' words were muffled by Dean's coat, but that didn't matter. "I've missed you more."
