Is it possible that the French woman Danielle is a member of the same group as these boat people?
All we know is her boat crashed on the island and they were a scientist team, lets say working for Dharma for example

, is it possible she was the last team from that company that made it onto the island and to try and take it over??
Is it possible Danielle did an agreement with the others to kill her team mates when she realised they were wrong about the island?
Seems strange she has sided with Locke, maybe to avoid meeting this new group as they might be wondering what hapened to their "team mates" 16 years ago.
Just a theory.
