Jack holiday fic with Santa and/or Krampus
Sam thinks it’s super cute that Jack writes a letter to Santa...
Dean mails it off because he’s cheeky and the lady at the post office (MARTA/DARLENE from Lebanon episode) had a Santa letter program.
///
It turns out to be a VERY BAD thing because Jack's letter has his signature, which is infused with a power that Christmas demons can use to TRACK him.
///
Cas finds out + instantly sees the problem; He realizes that Santa-adjacent figure must be on the way to kill or kidnap Jack. ("What the fuck, Cas? You want us to kill Santa?")
So TFW 2.0 is staying up late on Christmas Eve with the FULL intention of killing whatever tries to get past the bunker warding.
Visually, you get TFW trying to murder Santa.
