Torchwood season finale spoilers

Apparently in the second season finale, airing April 4, Jack's long lost brother Gray stabs him during an argument.

Also, there's a leaked script outline which may or may not be real. In a nutshell, Spike sets off bombs at all of Cardiff's nuclear facilities (plural?!), and whisks Captain Jack back in time 2,000 years. It turns out Spike isn't in control of his own actions, but is the puppet of Captain Jack's evil brother Gray, who's gone insane after years of torture at the hands (claws) of hellish creatures. They bury Jack alive, but Spike slips Jack a ring with a homing beacon.

Then Gray zips Spike back to the present. Spike nearly gets killed by Weevils, but Ianto saves him. Owen, meanwhile, is trying to keep all of Cardiff's many nuclear reactors from exploding. Gray shoots Tosh, who lives long enough to help Owen avert nuclear catastrophe. The radiation destroys Owen just as Tosh dies, so they sort of die together. Meanwhile, Jack has been locked in a drawer at Torchwood for 100 years after some Torchwood women dug him up in 1900. (They found the homing device that Spike gave him, but Jack decided to hide in a drawer for 100 years to avoid meeting himself.) Jack puts his brother "on ice" but lets Spike go free.

And then as the team clears out Owen and Tosh's stuff, they find a farewell video that Tosh left behind, addressed to Owen (who'll never see it.) Then we end with Gwen, Ianto and Jack sitting sadly on the docks of scenic Cardiff, land of a thousand nuclear reactors.
