Here's the backstory you need to know going into tonight's episode of Lost: Claire is Australian. Claire was preggers. She was kidnapped by Ethan, who we think was one of the Others and whom Charlie shot dead. Then she had a baby. Then Charlie went a little nuts, she stopped hanging around him so much, preferring the company of Locke instead, then Charlie tried to steal Aaron from her, and Locke punched him, but Claire still decided to heed Charlie's warning and baptized her baby. Also, in the last episode, One of Them, the group caught one of the Others. (Yes, I know within the world of the show, it is still not clear whether he is an Other or not, but since the name of the episode was One of Them, I think that should be telling us something).

Caught up? Good. Here we go. The episode begins with Aaron crying with a rash and fever in the middle of the night, and Claire waking Locke to go get Jack. Danielle shows up saying, "You don't remember, do you?" and Kate shows up yelling for Danielle to go away. She asks Claire what happened and Claire says that Danielle said "there's something wrong with my baby." Cue Lost intro graphics.
