Michelle R. starting to spill Lost's secrets?

Lost actress Michelle Rodriguez believes the season finale will generate even more mystery - with the characters of Jack (Matthew Fox) and Claire (Emilie De Ravin) possibly being related. In the show, Rodriguez's character Ana Lucia accompanies Jack's father to visit his Australian daughter - who isn't shown onscreen. Rodriguez says, "I believe Claire and Jack are siblings. But that's all left up in the air." [Starpulse]
