Focused on the search, Dean had not expected to have a hand reach out and grab his arm. His first reaction was to bring his arm forward and to throw the person off balance to point his gun at the attacker's head. But that was short-lived when he changed his action and grabbed the guy to keep him upright. "Shit...Sam, help me here!" The guy they had met earlier looked like he had held off many Vampires and paid for it. He helped the guy to sit on the ground and rest against a wall to keep him upright.
What surprised the Winchester was the request this guy wanted from the brothers. To watch over this 'Evie', which he guessed was the girl and be her guardians. What surprised him, even more, was the fact that she was the Van Helsing, the most famous and thought to be an extinct family in the Hunter community. It was quite the last wish, and this man was trusting us with his Ward. He glanced at Sam, figuring that he knew what his brother's answer would be. Looking back to the young man, Dean nodded. "I promise. We'll keep her safe and be her guardians." Giving his promise, placing his hand on the dying man's shoulder.
