Regarding possible Cable reference in X-Men Apocalypse

So at the beginning of the movie when Apocalypse is transferring himself you see something that looks like liquid metal, was that the techno organic virus or just a coincidence. Also do you feel like they will go the whole way of Mr.Sinister making a clone of Jean Grey for Scott can have the baby with her to make Nathan? I am just super curious on how they will add Cable to Deadpool 2.
