Was a great episode , i thought anyway how the machine unlocked the human dna and brought back one of our evoultions from the past that didnt work, and in 2 weeks ...............

CAPTAIN JACK Is BACK yah i think Captain Jack is ace and should be a constant character the only thing im pondering is ..

How did captain jack get back from the satelite 5 in the "something century" to the 21st century ?

and also the next episode will it show the where the doctor picks him up from torchwood or what guess ill have to wait to find out , but 2 weeks is ages
