That Sub-Zero IS a Quan Chi zombie. And that is also MK9 Scorpion, so he's still a wraith. My guess is that at the end of the Netherrealm War, Quan Chi tries to send Scorpion back to the Netherrealm and tells him the truth, after which Scorpion is saved by someone and either Socrpion or the person who saves him fights Quan Chi. After that the whole Shirai Ryu 2.0.
