*Lars appears from the kitchen...he's obviously been drinking*
"NOOOOOO, YOU'RE NOT GOING TO BURN ME! I'm not one of those THINGS! ALL I DO IS OBEY! 'Lars do this' - 'that kind of kills my buzz man, but, okayyyy, for the good of the group' - 'LARS, DO THIS!' - 'aww, but, really? I TRUST him, ehhh...okayyyy, for the good of the group." And now you just want me to SURRENDER like a good obedient pushover?! NOOOT going to happen! NOT WITH FIRE!!! You're going to have to catch me!"
With that, in his longjohns and nothing else, he grabs the keys to the bus from the counter, an axe from the wall, and a(nother) bottle of booze from the cabinet as everyone stares on, watching the show.
"OUTTA MUH WAYYY!" He raises the axe at his onlookers and charges, not at them, but through them, and they part quickly as he stomps through and runs out the door screaming : "I'M NO THING YOU FUCKERS!!!! I WON'T BURRRN - ANNND I'm taking these keys with me...NO BUS FOR YOU!" His voice trails off quickly as no one follows out into the cold and it gets swallowed by the elements. They shut the door, knowing he won't get far, but knowing they've got to go after him and incinerate him like the rest.
You all realize he's clearly lost his mind. A quick blast of flame ends him outside, deep in the snow. But it becomes all too clear what he was.
