After weeks of searching, he assumed they were deceased or worse. He strives on, his final words from his parents were, "Be strong, don't get into trouble. Running isn't for the weak." and those were the words he's lived on ever since. Now he tries to avoid big group and the undead. He hasn't given up hope, he searches for his parents everyday in an effort to find them. It's the only thing he has left in this world and he wont lose it.
