Upon hearing the question Sagan was certain he could feel an electric shock going through his body. The last thing he wished to have brought up in a conversation was his family. After all, they were the reason he had snuck onto the ship. He'd grown tired of his abusive father and alcoholic mother, not to mention the fact that he was the sole child in the family. Sagan didn't show any sign of movement for a while. After all, he'd rather die through painful digestion than to be back with his family, and explaining their relationship didn't seem like it would change the situation. He ultimately shook his head to indicate he didn't have a family, rejecting the idea of having his parents involved.
