Sadly, this is the final chapter. But you never know, a sequel might come along one day...

The Winchesters never stuck around in one place for too long and it was rare that they would ever miss where they were leaving. However, this seemed to be one of those unique times in which those two rules did not apply. Nick had finally managed to get the Impala out of police hands- for which Dean momentarily looked like he would straight up kiss him. It stood proudly outside Nick's house with Dean and Cas sitting next to each other on the hood and Sam lent by the passenger door and laughing at some awful joke Trubel had just told him. Nick and Juliette smiled and looked over at each other before joining them down by the car.

"Well, this has been one hell of an eye opener" Nick smiled over at Dean who rolled his eyes.

"You're telling me" Dean muttered in reply, but he still couldn't stop the small smile flickering across his lips.

"It's weird to think there's a whole world of monsters out there we can't even see. But I'm glad there are people like you out there fighting them" Sam said mostly to Trubel who seemed to frown, smile, blush, and punch Sam in the arm all at the same time. He laughed and ruffled her hair in reply, which only made her both more annoyed and more embarrassed.

"I guess this is goodbye" Dean said with a hint of well-disguised sorrow as he stood and wandered over to the driver's side of the car.

"Well you never know, we might run into each other again one day" Nick smirked.

"Somehow, I think you might be right" Dean nodded back before opening up the car door and ducking inside.

"You'll need to be careful. Demons are unlikely to fully believe in the existence of Grimms, but there will be others out there searching for you" Cas said as he approached Nick.

"I'm sure we'll be fine. A demon trap and a bit of salt is all we need, right? And if it ever gets out of hand, we know who to call" Nick joked and after about five awkward seconds, Cas let out a little chuckle. He took a step back, quickly warned Nick and Trubel to shut their eyes, and then disappeared.

"Woah" Juliette gasped, staring at the space in which the angel had just stood as Nick and Trubel blinked back into reality.

"Well, we should really get going" Sam announced, stepping around the Impala to stand in front of Nick.

"It was great meeting you"

"Don't lie, it was the worst thing possible thing you could have ever dreamed of. Now you know what's really out there"

"Yeah, but at least we know how to deal with it" Nick smiled and Sam let out a small, almost sympathetic laugh. He patted Nick affectionately on the back before turning to Trubel.

"I hope we meet again one day" Sam smiled and pulled Trubel into a hug.

"Me too" she mumbled into his shoulder. Eventually, they let go of each other and Sam nodded his head towards Nick and Juliette before climbing into the Impala next to his brother. Juliette smiled over to them before turning back towards the house. Trubel smiled and waved at Sam as Dean started up the car before she followed Juliette towards the house. Nick raised his hand to wave but stopped suddenly. Dean's face flashed before his eyes; the once human features became a horrific mask of swirling black smoke. But just as Nick blinked it was gone, and Dean was smiling once again. The Grimm shook his head and gave a short wave.

"Did you see that?" Nick asked Trubel quietly, his eyes not moving from the back of the Impala as it disappeared down the road.

"See what?" Trubel asked, confused. When Nick gave no reply, she tugged at his arm a little. Nick shook the last of that image from his mind and followed Trubel back up to the house. The demon was gone, they were safe for now. Nothing could possibly be wrong with Dean.

Nick figured he was just imagining things.
