Why not the third time?
It happened to Miguel twice, why not the third time?
He was cursed and went to the land of the dead. He came back because he was blessed by a family member but when he took the dead's guitar again, poof, he went back to the land of the dead.
Well, when he came back for good, the first thing he did was grab that guitar again. Was there a stated reason as to why taking a dead person's belonging didn't curse him?
