Omi: It started with the wind, on a cold night, much like this. It was almost Christmas, but this Christmas was darker, less cheerful. But I still believed in Santa, in magic and miracles, and the hope that we could find joy again. But our village had given up on miracles, and on each other. They had forgotten the spirit of Christmas, the sacrifice of giving, and my family was no different. I tried to help them to believe again, but we were no longer the loving family I remembered. They too had given up. And eventually, so did I. And for the first time, I didn't wish for a miracle. I wished for them to go away. A wish I would come to regret. And that night, in the darkness of a howling blizzard... I got my wish. I knew Saint Nicholas was not coming this year. Instead, it was a much darker, more ancient spirit. The shadow of Saint Nicholas. It was... Krampus. And as he had for thousands of years, Krampus came not to reward, but to punish, not to give, but to take. He, and his helpers. I could only listen as they dragged my family into the underworld, knowing that I would be next. But Krampus did not take me that night. He left me, as a reminder of what happens when hope is lost, when belief is forgotten, and the Christmas spirit...dies.
Omi: Like he had for thousands of years, Krampus came not to reward, but to punish. Not to give, but to take.
Aunt Dorothy: So what kind of godforsaken concoction are you whipping up now? You know how this fancy food clogs my pipes.
Sarah Engel: Well how about we go to your trailer for Christmas next year, hm? And after you spending weeks decorating and cooking and cleaning, I might just waddle in and start bitching and moaning about everything you worked so hard on.
Aunt Dorothy: Oh Sarah, you know I.
Sarah Engel: No, Aunt Dorothy, please! For your sake, just... stay the hell out of my kitchen.
Linda: You let them go to the bathroom alone.
Aunt Dorothy: There was another option?
Omi: Please, listen.
Aunt Dorothy: English. I knew it.
Max: I don't even know how to drive a stick. We have a hybrid.
Linda: It's Christmas. Nothing bad is going to happen on Christmas.
Aunt Dorothy: I'm old enough to know when life is coming at me with its pants down.
Answer: The ending is that they are all alive and Krampus gave them a second chance. Evidence of this comes from the director's commentary and the comic book prequel "Krampus: Shadow of Saint Nicholas".
