AUTHOR NOTE: This was a live imagine I wrote out in a group chat on Instagram.
You and the hunter trio were trying to track down a witch. She had been casting spells on men causing them to kill the one they loved most. You weren't sure why. You had tracked her down to a small house on the outside of town.
"Maybe Cas could zap in and smite her," you suggested, "fast and silent,".
"Sounds like a plan," Sam said.
"Just don't let her see you Cas," Dean said. The angel nodded and fluttered off. About ten minutes passed and Castiel was still gone.
"Should it be taking this long?" Sam asked.
"Maybe he's waiting for the right moment," you suggested.
"I don't know guys," Dean said, "I got a had feeling,".
"Do you wanna go check it out?" You asked.
"Yeah," he said. You all made sure you had your witch killing bullets loaded in your guns and headed to the little house. You reached the house and Dean slowly opened the door. You all walked in and looked around.
"It's kinda dark and quiet in here," you whispered.
"Too quiet," Sam pointed out.
"Cas," Dean called out. You all heard a noise coming from the basement.
"Should we check that out?" Sam asked.
"It could be Cas, so yes," you said as you headed down the creaky steps one by one.
You got down there the only light in the room was coming from the windows. "Cas?" you called, "are you down here?". There was no answer, but instead, you heard a rattling sound coming from behind a big box. You looked at the brothers as you started toward the box. You reached and looked back at the boys as you got your gun ready. Dean nodded. And you step out from behind the box with your gun held up high. You stopped dead in your tracts.
There wrapped in Castiel's suit and trench coat was a little boy. He looked to be about one year of age.
"She took Cas and left a child?" Dean asked. You noticed the dark blue eyes and black hair the baby had.
"No Dean," you said, "that is Cas,".
