Sort of. [ Ned rubs the back of his head awkwardly; he doesn't want to give people the wrong impression and have them thinking that he can just bring them back if they get themselves killed ] All it takes is one touch, yes. But there are two complications. If I touch the same thing a second time, it goes back to being dead, permanently. And... and if I bring someone back for more than minute, someone else dies.

[ Bolstered confidence aside, Ned still looks away from the communicator as he says this. ] So it's a kind of exchange, really.
