Speaking as a general "Ana Lucia hater", I'll say that she showed a lot more possibility for redemption here than I thought she did in her background episode (which I thought would give me some grounds for liking her, and instead made me snarl at her).

She didn't growl at Charlie even though it must've been sorely tempting; she apologized to Sayid and tried to explain herself. I didn't think the 'nobody likes me' thing was an 'Oh, woe is me' ploy. Here's what I got out of it--

"People I barely know have judged me for a mistake. But not only were you directly affected by that mistake, you also dealt with my behavior afterwards, and yet you don't seem to hate me, even though you'd be fully justified. So I want you to know what's going on, at least as much as I can manage to get across, because sitting around a campfire and sharing feelings is not exactly my strong suit."

Maybe I'm reading too much into it; I don't know. But I actually saw potential tonight.

And I'd better stop, or I'm going to be tempted to write fanfiction. ;-)
