Scorpian doesnt die, he is already dead....Drahmin turned back into his human form...as far as the deadly alliance goes..I think the alliance is finished..but Shang Tsung is definately killed by Kung Lao. That means Quan chi is still alive...but I dont think he has the amulet needed to control the Dragon Army.

Drahmin turns into a human but you cannot see his face until Deception. Kung Lao destroyed Shang Tsung and I think Liu Kang destroyed Quan-Chi because in Quan's ending it showed liu's soul going into kano's body and then Quan-Chi is looking at kano and then it says liu had returned in the form of kano's body. Scorpion is not dead, he was just getting tortured buy those demon things in the green pool, Moloch didn't die because he didn't die in any of the other characters ending so he could be possibly in Deception also.

Apparently, you will see what happens to the Deadly Alliance at the beginning of Deception.

If Drahmin comes out as a human, wouldn't Moloch want to eat him, seeing it says the Oni's feed on mortals?

Maybe he will, It does make since huh? Maybe the truth will come in Deception.
