Watching first season DVDs of Torchwood, and the episode ends with Jack walking off into the darkness around Roald Dahl Plas, and I have the random thought of Jack being hit by a bus. Which won't hurt him, ultimately.
And I gotta say, that's kind of how I wish they ended every episode, with Jack just randomly and wantonly being killed in increasingly pointless ways.
"Well, that's another job well done, gang!" *anvil crushes Jack from above*
