wait. I have a twin?

this can't be happening again!

When Cas, Kayla's sons and Dean arrived at home from the movies. Cas searched almost the whole bunker but neither Sam and Jack are bound to be seen. "I'm gonna go to my room! I'm tired!  Gotta take a nap see y'all later!" Nathan grumbled. Everyone nodded in approval and Nathan was off to his room. Cas searched almost the whole bunker to surprise Kayla with open arms but she wasn't there, neither are Sam or Jack. Cas tried to go up to Kayla's room but once again she wasn't there when Cas started to get worried and panicked "Dean!!" he went up to where assumed Dean would be and to no surprise he was there...in the kitchen, munching a cherry pie Kayla made yesterday!  "Kayla, Sam and Jack aren't here! Did you call them to see where they are?" 

"Didn't have to! When I went over to the fridge to get a pie, I saw they left a note on the fridge" he said showing him a written paper. "Just a werewolf case. Should be fine." he said taking another bite out of the pie. A part of Cas relieved but another part of his was a bit protective. What if she gets hurt? Or Jack. Cas loved that kid as though he was his own. 

"So uncle Dean" John came up from behind Cas catching him a bit of guard. 

"Yeah kiddo?" Dean said putting up a fork from his pie up his mouth. 

"I was hoping, If you can teach me how to become a hunter" John told him ecstatically. Dean stopped half way from shoving the pie in his mouth and put the plate down and slowly turned to explain "If I do, your mum would kill me and to be honest I don't like it either kid. You should carry on with a regular life. It's dangerous living like me and your mum. Me and everyone else would want you to be safe." 

"But I've been practising." 

"John. No. Just let this hunter life get past you" Dean begged. John looked down and sighed "alright." he pouted. 

"Good. Best not mention this to your mum" Dean gently told him. John looked up at him before nodding. Dean pulled his nephew in for a little hug and patted his back. "ok! Gotta go finish that comic book! Batman is driving me insane!!" and with that, John rushed to his room leaving Cas and Dean chuckling at his words. 

"Hey Dean" Cas said before he walked up to him. "Can I talk to you?!" 

"don't have to ask that Cas. Just tell me" Dean replied before he went to put the pie back to his opened mouth.

"Well, I was reading online about weddings. And it says that the groom should have a best man and the first person that came to mind was you... would you like to be my best in my wedding?"  

Dean stopped munching his pie and just stared at Cas for a second, silence filled the room leaving the angel a bit uncomfortable and keeping a tight awkward smile with his lips. Dean gulped his pie down his throat after he realised it was still in his mouth. "Cas y.. seriously?!" Dean asked startled. Cas nodded "yes Dean. I want you to be my best man. If you want" Dean grinned widely "Cas!! I would be honoured! Thank you!" 

Cas smiled and went over to hug him in a tight bro hug. "Thank you!" Cas exclaimed with a grin. "No problem at all! Thank you for choosing me to be your best man Cas. It's gonna be a real honor! AND! I already thought about the bachelor party" Dean said with a smirk. 

"Oh! I read about those..One article said that they got the groom drunk and stripped him naked in front of people." Cas said with a rather uncomfortable confused look on his look "please don't do that to me" he said in a low begging voice. 

Dean now felt a bit uncomfortable before he cleared his throat before he tried reasoning and explaining to him "Cas! Those are idiotic things. Your bachelor party won't be that way. Don't worry" 

"Thank you" Cas said relieved. 

Seconds later, The door opened and revealed a bright grinned Kayla, a half angel, 1 hunter and 1 new blonde girl behind. "wadup amigos!" She said before she skimmed down the iron stairs as she spotted Cas first. Cas grinned at her sight "there's my future wife" he said before he grabbed her into a kiss. "How is my future husband?" she cutely smiled at him their nose almost touching each others. "he was good, Missed his lady though. Who is this?" Cas asked gesturing at Britney. "Oh. That's Britney, Apparently her and Jack are love doves!" Kayla grinned at the 2 young people. Cas grinned at them "Well pleasure to meet you. I'm Castiel, Jack's adoptive father. That is Dean, and you probably know Sam already and Kayla"
