Nameroc feels no emnemity to the badger; it is, after all, just a scared animal, cornered and with a companion dead or wounded; whats more, the elf had foolishly made eye contact. He brandishes the flaming sword at the badger, hoping to keep it at bay with fire, and makes for the door, closing it behind him.
Game stuff: Move for the door, ready action to strike if the badger comes close, then shut the door.
