This scene convinced me that this was like a very super ambiguous secret subliminal remake of the second Mortal Kombat Movie.
It dosnt have to make sense, which is why I think this scene is so similar to something we might see out of Mortal Kombat.
Its like....
Sindel vs. Johnny Cage in Shang Tsungs Palace, while he Watches. He even talks about Immortality.
Then Kung Lao, Bo Rai Cho and Li Mei (or Kitana, which ever you want to see her as, since she does fight The White haired lady) show up and save Johnny Cage.
Li Mei tries to kill Shang Tsung for enslaving her people and making them build his palace, but fails utterly.
Shang Tsung goes all crazy like and uses some magic to open a portal to the Netherrealm.
