Isn't it cool how when Kung Lao played against Scorpion, with Smoke and Jade clues on, the message from Smoke when he appeared was "Prove yourself" while when playing against others would've been different? It's because Smoke is one of the three ninjas (henceforth his other message: "I'm one of the three").
Also, both smoke and Jade revealed their names and when he played against Jade, Shao Kahn would say her name when she won, whereas without the clues on, he wouldn't say anything when she won. Also interesting to note is when Jade says "I'm one of the three" mirroring the ninjas but for female: Kitana, Mileena and her.
Also interesting to note that when fighting Shao Kahn nobody says who's winning as it's Shao Kahn himself who says that, only that now you're fighting him.
