You were always traveling with groups of people and some how they'd toss the responsibility of leader to you. You weren't the greatest leader in your prospective because each group would get killed in some horrific way. You were tired of the responsibility, tired of getting them killed. You didn't want to be the leader, you wished to follow someones lead and hope they are making choices for the good of you and the group. That wish comes true though in one odd form. A Hunter, a type of special infected, has been keeping tabs on you for quite a long time. And finally decides to take action when the responsibility of being a leader almost ends you. Some how life changes for you and in a good way. And a little spark of love appears in your new found situation.
