Flock did a good thing, I think, when he lied to Claire about the Others having taken Waaaaaalt her baaaybeee. If Claire had thought that Aaron was dead (or perhaps that dingoes had taken him--she is Australian, it's tradition), she might be searching for FedEx boxes full of VHS tape (possibly with taped-over Red Sox games) so she could make a rope to hang herself with. But if she thought Aaron was alive and being mothered by the Othered, well, then she has hope and hate, both of which will give you a reason to wake up in the morning.
Speaking of death by video tape, I bet there is a volleyball somewhere in Dharmaville. It might be less creepy than the skull. But I must say, personally, I like creepy doll Claire and her creepy doll.
And when Claire tried to kill Kate? Sayid, you could have been a gentleman and at least grabbed Kate's arms. Just because Claire was more than capable doesn't mean you should eschew chivalry. Sheesh.
