Everything was going wrong for Stephan. As he wanted to apply his plan into action, it failed because of a simply miscalculation; Soprana wasn't a woman used to adventures. He literally accidentally poured oil on fire when he ran to the door and turned around to jump backwards. He trusted his luck too much that he almost got sliced by the scythe the skeleton swung suddenly.
If it wasn't for Soprana who pulled him by the collar, he would have been dead. Now his chance to get into whatever was behind that hut was lost because of the ex-witch. In a moment, the situation changed to both of them running for their lives deeper into the forest. Why did it happen? Because a certain witch didn't trust his judgement. He almost felt something submerging him and taking him somewhere else.
