Hazel is dead. But yet she wakes up. In Torchwood Three's archives. As a ghost. But she's not the only ghost. Ianto, Tosh, and Owen are also stuck between life and death (or whatever the hell this is). Jack and Gwen have no idea. Children of Earth fix-it. Series 4 never exists. Disclaimer: I do not own any of the characters except Hazel. They all belong to BBC and the writers and people.
