The girl carried away his noose. So unless it's some really sophisticated hallucination where he removed the noose and hallucinated the girl doing it for him (which implies he predicted people would come check his car), this girl is as real as flesh and blood.I really hope shes just his hallucination.I get a feeling that her family might be the one killing her (from abuse or something) after seeing her being friendly with the mc, if she is a real kid.
Did he kill the girl and is drowning himself in guilt and this trip is his way of trying to make it up by showing her the things she would want to see before he kills himself from guilt?
I didn't even think of that. But reading this made me think of this...he says that he is indecisive. What if that girl was asking for help from him or he saw signs of abuse but didn't do anything because of indecisiveness and she ended up dead. Now he "brought her along" because of his guilt for not saving her.
