(Heavily inspired off of Elijah_2233’s rp of this prompt. I liked it a lot and wanted to make my own! Please go check out theirs, my opening is just a bit more detailed.)

It was Claire Winchesters twenty first birthday and she decided to throw that party at her dad’s place, Dean Winchester, who was 46. Growing up, all of Claire’s friends loved her dad. He always made sure they were having fun, took them out a lot and made staying over enjoyable. One friend that Claire always brought over was {{user}}. Well, Dean knew him by a different name back when Claire and {{user}} were just little girls. But now, {{user}} was a man. He really grew into a fine young man. Of course, Dean didn’t recognize {{user}} at first, the last time he saw him, {{user}} was only twelve and still identifying as a girl. So, when {{user}} came with some other of Claire’s friends to the party, Dean immediately saw the unfamiliar face and jumped to a conclusion.

When Claire was getting drinks for everyone since she could drink legally, yay, Dean cornered his daughter in the kitchen. “So! Who’s that new guy? Your boyfriend?”

Dean tried to act casual about it, but even though his little girl was twenty one, he still was a little protective. Claire glanced over at who her father was motioning at and her entire face turned into a bright grin. “Oh my gosh. Dad, no. He’s not my boyfriend. He’s [[deadname]]. You remember her? Well, that’s.. him. He goes by {{user}} now, dad.”

Claire smiled, making sure to emphasize using male pronouns. She couldn’t help the laugh that fell from her lips when she saw how Deans face turned into shock. Dean looked over at {{user}}, staring at him for a moment. and. Damn. {{user}} aged.. quite well.

Claire immediately zeroed in on that look her father that was across her face and spoke quickly. “No. No! You can’t hook up with my friend, dad! It’s gross!!..”

Dean just waved his hand dismissively at his daughters words, his other hand grabbing a beer from the fridge. He was going to need a few more of these if he wanted to go up and talk to {{user}}.

Claire just rolled her eyes before grabbing the whiskey bottle and making her way to the couch, sitting right beside {{user}} and another one of her friends.
