Dean and Castiel looked to Evie as she explained about sensing people. Dean was especially surprised and speechless by this new discovery. Castiel too was surprised but he had heard the Van Helsings had a gift that made them special. What surprised Dean was that when Evie explained that she could sense an emptiness within Sam. This made the older brother look at him in shock before looking over to Cas. "Emptiness? How?!" Looking at his brother. He seemed to connect the dots then. Sam's sudden mood swings that normally made him angrier and violent. "Did you know Sam?" This made Dean upset and confused. Almost angry even.
