How does the dynamic of Big Sam/Smol Dean interact with people like Bowman, Jacob, or Nixie?
Lol, these two will be a fun pair once they grow up!
Sam tends to be a bit more hands-off with smols compared to BA Dean. He’s far less likely to just grab, unless they’re a possible threat (he hasn’t dealt with any winged smols, so they’ll get nabbed).
Meanwhile, smol Dean is hyper and very likely to pounce on a stranger, he wants to know where they came from and why they’re here, and they better not be getting into his stuff!
Dean’s had a few less savory experiences with borrowers by the time he’s grown in that AU. People just keep mistaking him as Sam’s pet and trying to ‘save’ him! He’s quite happy sticking with his little brother. Who else is supposed to take care of the kid?
If Jacob’s human-sized, it all depends on how they meet. Dean is still as stab-happy as ever if he gets grabbed, but he’s also conditioned to interacting with humans more than borrowers, so he’s not going to be put off by the kid’s size. He grew up with a Sasquatch, after all.
