*WARNING: Potential Spoilers:
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."
