Dean decided to find a place to settle and try to make that meat more edible before he got to eat something.
Dean got even weaker than before, and it was hard to think that it was even possible. His mind seemed to be crumbling inside out. He knew that, now that he got something to eat, he would carry on without worries. But it was still a struggle to do anything with his mind like that.
'I will never let my body come to this stage of exhaustion anymore. Man... I feel like it's a hassle just existing while in this state.' It was an excruciating feeling when you couldn't bear with your own self.
Dean's will was to just skip to the time when he would already be dead or filled with meat and satisfied. Any second more like that was a punishment.
