He watched the girl speak with her pissed tones and realized his attitude was all the difference. The only reason he spoke to her like that was because, he was uncertain of who he could trust in this world anymore. After what had happened in the village with his home and parents, there was nothing left for him and he was cautious, but presented himself as a cocky bastard, trying to force people to tell him their business so he was able to know if they were trustworthy or not. Even then, how could he know if a person was even giving him information that was true. It could all be lies just to shut him up. 

"I am sorry. I'm not in the right mind after what happened at the village, with my house being burned down and my parents burned alive inside. I don't mean to come off this way, but since that incident I am very cautious about things and people and who to trust. Sorry if it offended you, as that wasn't my intention. Maybe we can put this all behind us and start with a clean slate? I'd like to find out anything that you might know."

Why did he even tell her about the fire, what made him open up for the brief moment he divulged that information. He just wanted to be accepted and after being seen as what the village considered "different", there was nothing for him. That's why he became a loner, but now that he met these two, maybe there was some sort of friendship to be had. He could hope right?
