Two months later...
It had been three months or so since Dean fell on that cave. Two months since he entered into the lower levels of that place and went further in order to explore everything and find a way out.
He began to lose his hopes that he would find another path that would lead to the surface, but it was unlikely that he could just come back all the way he did up until that point. Also, each day was making him stronger than the previous one, so there was an advantage in staying there.
Emperor's Touch didn't bother him about his pace at all. It didn't punish the boy because he intended to go each day at a time to get more and more powerful, so he kept taking it easy and going slowly.
After two whole months, the boy was able to do great progress in his exploration. It became easier to travel through that place as he got used to it.
Dean was walking through those familiar tunnels that he struggled so much to memorize.
