Captain Jack Harkness reveals he's made a fatal error, in a new featurette for Torchwood: Miracle Day. Here's an exclusive first look at one of the new character-centric featurettes being unveiled for the fourth season of Doctor Who's edgy spinoff.

We've never seen Captain Jack look quite so shaken... even at the end of Children of Earth.

There are other Torchwood character featurettes going online around this time, and they seem to be part of a new viral marketing push for the ten-episode miniseries, which launches on Starz on July 8. Who do you think Esther Drummond is? What sort of conspiracy would be able to put a stop to death simultaneously, all over the globe? And why do you think Captain Jack looks so scared? I guess we'll know the whole story soon enough.
