A wolf who had a very bad day, taking on a wrong gramma
Grandma got run over by a Reindeer, then she slaughtered it for Christmas dinner.....
Santa: “Where is Donner??”
That’s some axe, too. Probably made of steel scavenged from some unlucky tiger tank that had the misfortune to pass through her village.
Then in the evening, not knowing whether the next day would be her last, she drank vodka and partied and ate (not that there was all that much good food around, mind you) like it was literally her last night on earth.
Then she'd get up the next morning and go shoot more nazis.
Obviously at some point she must have gotten some practice taking them out in a more up close and personal sort of way.
Gee... all those years in between... I wonder what must have happened to her husband when he messed up...
Just sayin'.
