I've wondered since the first we saw her if Danielle was an Other.

She really seemed to want to kill Patchy, and tonight she interrupted him when he was about to reveal Locke's secret. She led them right to that barrier. I think she's behaving suspiciously, more so than usual.

Do you think she is an Other? What other "evidence" am I missing?

It's not from this episode, but she refused to go into the Flame... I'd say that's a bit suspicious.

She's not an Other.

But she KNOWS more about the Others than she's ever let on!

I don't know if she's an other, but she sure is acting suspiciously. These past two episodes will be interesting to think about when we learn more about Danielle. I would love a Danielle flashback.

i've always suspected her as an other also, or at least someone who cooperates with the others.
last episode, which was just earlier in the same day as today's episode, danielle was so insistent on not encountering any others that she would not go with them. now she's happily going along on an excursion into the other's camp.
and last season she wanted to get her daughter back so bad, she stole aaron to make a trade. now she tells kate she doesn't want to even know about alex. she makes no sense.
and what happened to her being crazy? wasn't she crazy in the 1st season? now she seems normal (well as normal as she can seem).

i think that danielle was outed by the others. eventually we will see that she has the same mark on her somewhere that juliette got a couple of weeks ago.

I've been wondering about her too. She likes to interrupt, and change courses over conversations. What is she hiding??
