The Torchwood cast and crew participated in a Q&A panel at San Diego Comic Con today, and you can see some great photos of the event on the Starz Flickr!

Digital Spy has a live blog of what was revealed during the panel, with one of the most intriguing revelations concerning Episode 7 of Miracle Day, which John described as “heavy and shocking”. “You learn a lot about Jack and Gwen in that episode,” he teased. “Russell said that episode was a gift to what we’d done before. You’re going to love that episode.”

A brand new trailer for the series was also premiered, which you can watch online here.
