Of course, I understand where you're coming from with the nitpick. I was kind of underwhelmed by it the first time I saw it (I think mainly because I just did not want the movie to end), but it's grown on me a lot.
In BB, in his private jet, Bruce does say that he wants his symbol to be " everlasting "
