Among some of the other ideas I've heard about this supposed episode title, there's one that I immediately thought of when I saw it. It could be a reference to Marty Robbins's "El Paso," in which the narrator returns to the town in which he was wanted by the law for murder in order to see his beloved Felina one last time. He is fatally shot by the lawmen, and dies in Felina's arms. What do you all think? I could definitely imagine a similar scenario occuring in the show's finale.
