Here is chapter four. Poor Sam and poor Dean, but mostly Sam ;)
Sam sighed as his brother left to fetch the newspaper that would have arrived at some point during their morning of unwelcomed revelation. Walking over to the basket Sam smoothed the blankets and felt underneath them. The sheets were still warm from where Huntress or more so Celeste had slept and he had to fight back his tears of loss. His fingers brushed against something cold. He pulled out a picture of the three of them. Dean and Sam were laughing holding an ice-cream cone each. Dean had vanilla and Sam was holding up a strawberry scoop. They were laughing as Huntress had leapt into the air so all four feet were of the ground with her tongue lolling out as she was trying to snap Sam's ice-cream out of his hand. Why do we always lose the ones we love? Sam thought to himself as he wallowed in self-pity. It was evident to him that Dean was taking this pretty hard as well, he was often aggressive to those he cared about and Huntress had been one of them.
"Sammy looks like we got a case," Dean's voice broke Sam out of his wandering mind as he watched his brother hold the newspaper up high and give it a shake.
Sam made to call Huntress and was hit with the realisation that for the first time in a whole year it would just be him and Dean working a case together. Celeste had seemed so genuine and Sam could not help but feel as if Dean was making a big mistake allowing her to go off by herself. However, as he followed Dean to the impala and sat down he was comforted by one known fact. If Celeste was as strong as Huntress then she shouldn't come to any harm. And why should she? After all she had revealed it was impossible to kill a creator's child.
"Dean. Do you think it's true?" Sam asked his brother cautiously as Dean began to turn onto the road leading away from their bunker.
Dean grunted in response as he concentrated on the map that was balanced precariously on his dashboard.
"That creators children cannot be killed?"
"I wish you would just drop it Sam. That bitch is gone and if she comes back I will find a way to end her. Besides if dad taught me anything it was, there is always a way to kill anything that isn't human. Nothing can exist forever. Even if it is from the other side," Dean casually answered his brother with a gruff tone and prayed to no one in particular that his brother would stow the subject in his big head before he lost his temper and said something that he would regret.
Besides it was a five hour and twenty-five minute drive to Oklahoma and Dean could not stand the thought of Sam talking about Huntress alongside whatever mushy crap he would have on his mind. Focusing on the road Dean attempted to push that mutt as far from his mind as possible. As far as he was concerned Celeste had never existed; she was just the nightmare that had ended the dream.
