I'd like a piece of advice on it:

I played yesterday with a friend, i got Raiden and he got Quan chi. We played the "test your sight" minigame, lvl 6, or max, i can't remeber. I won,my friend didn't. I pushed some buttons laughin', and, just after "failure" and "success" appeared, Raiden punched Quanchi, who looked surprised and walk back. Did it ever happen to some of U? can U control this, or is it a ramdomly effect? Is it the "last secret"? )
