WHAT IS THE SIGNIFICANCE OF THE LAST SCENE OF ‘THE WOLF OF WALL STREET’?

The significance is condensed in an anthological phrase that DiCaprio pronounces at the end of the movie. He slurs the words because his head is smashed through a brick wall. But you hear him mutter something like “Where’s Shprintza?” The first thing that strikes us is that there is no such character called Shprintza. For some reason, in this movie there are a lot of characters whose names are omitted. For example, the name of the restaurant woman is not mentioned. I don’t mean the woman sitting with DiCaprio, but the blonde one in the back who is focused on dressing the salad. We are also not told the name of the valet. Just what on earth is going on here? What are they trying to hide from us? A plot to overthrow the government? I’m afraid that is the only possible explanation. So, DiCaprio has discovered the machination but he’s keeping it to himself, probably to avoid retaliation. However, at the end of the movie, he lets out that enigmatic phrase which gives him away: “Where’s Shprintza?” It’s obvious that he is suspicious of that Shprintza and doesn’t want to let her out of his sight.
