Doctor Who ‘the poison sky’ prediction
I think that the gas isn’t actually gas, but really it is a teleporter device where 1 particle of gas teleports 50 sontarans. Then they will shoot the humans and afterwards, get out a shotgun.
Then they will shoot the humans heads off, take their heads and put them on their feet. Then they will go ice-skating and fall in love with the doctor. They get married and have a child; hence ‘the doctors daughter’
Obviously, i am correct :P
