From Autumn on the message boards:
From what I've heard it [episode 7X02] has something to do with finding a liver for a child.
I know. It sounds odd to me too. More info as I get it.
Small Leia side note: I'm adding this episode as 7x3 because as far as I'm concerned, episode 1 will still be the season premiere, no matter what the shooting schedule. So if the order here is a little different than what you've seen on other pages, just go with it. :o)
