Yeah , gut get this.....normaly at the end of an episode they usually end with orchestra...BUT this time it ended with The Superman Music right after he threw the stone at that cold place he was at.

Who knows wut hold 4 the next season?... we'll just have to wait.

because the episode ended with heroic music, it might be that clark creates the FoS

Everything certainly points toward the FOS. It would be rather foolish if, for some reason, they decided to do something else entirely. They must know that Superman fans will most likely be expecting it all summer.

Yeah it's definitely the FOS. I think that the crystal that formed after Clark united the stones is the same thing as the green crystal from the Superman movie. So I think that at the end of the episode when Clark threw the crystal, once it hits the ground it will start to form the FOS as it did when the green crystal was thrown in the Superman movie.
