"Torchwood: Miracle Day" writer Jane Espenson Friday gave fans at San Diego Comic-Con a little tease about what to expect for the rest of the season: flexibility with the timeline, romance, darkness, big implications, losses.

"This is about ideas," she said. "Think of the big picture as you are watching." As in, what would happen to wars, to families, to food supplies if Miracle Day really happened. "There's a lot there."

Before the panel got started, fans were shown the new trailer above, which gives us some clues to where things will be going. If you want read more about what happened at the panel, check my live-tweets on Twitter. My handle is @showpatrol, and I hash-tagged #Torchwood #SDCC.

I'll have more from the press room later.
