Thanks to Rachel for sending this through and for StillLost5 from Losttv-Forum for the following. I'm going to place this behind an "Are You Sure" button because IMHO they are quite major. I've confirmed these with one of my contacts, "I like visiting friends very much".
DO NOT POST OR DISCUSS THE INFO HERE IN ANY OTHER THREAD, ONLY THIS ONE. PLEASE BE RESPECTFUL TO OTHER LOST FANS WHO MAY NOT WANT TO KNOW. ANYONE CAUGHT CROSS-POSTING THESE WILL BE BANNED IMMEDIATELY.
NOTE: You can additionally discuss this in our Major Spoiler thread in the forums.
Eloise is not portrayed as a villain because she doesn't know (at the time she kills Faraday) he's her son. She learns of his plans through Jack and Kate, and tries to see them through with the help of Richard.
