The old timeline fed directly into the new timeline by virtue of Raiden sending visions to his past self right when MK1 started. And because the time travel was only to the start of MK1, everything that happened before it has been retcon-proofed for all eternity. Period, end of discussion.
He talked in MK4 and Deception as well.Reptile is better in this game. I didn't like him in mk9 he was rather meh. But hes faster in this game with more moves and a better design. I just hate that ugly unmasked look with his invisible variation. And finally he can talk. Only bad thing is he will be a lackey once again.
Some story line progressions take forever with even more regular characters such as Scorpion.If its a playable character i dont think they should be relegated to lackey status. Its sad to see that with Reptile, Baraka, and Ermac. They should have goals and rivalries and key moments like any other character. Reptile isnt my favorite but im sympathetic to the notion that he always gets the backseat.
