User blog comment:Western Gen/Speculations for Season 13/@comment-60.49.68.36-20150413005425

So, I've reading a lot about the number 57 in various forums. Few of them refer back to the original Blood Gulch Chronicles episode 57. In the Season 3 finale, someone or something has just obliterated O'Malley and his army. After that, when Church talked to Gary about the identity of the Great Destroyer, unknown him, he is about to be attacked by an Sangheili.

What if 57 is not/ not only foreshadowing the return of the Sangheili, it/also foreshadow the reveal/appearance of the Great Destroyer.

If you remember, Gary/Gamma, if his story is true, claims that the Great Destroyer is a being that is prophesized to bring death and destruction to the entire galaxy.
