Here's an interesting Rosseau point from Lostpedia:
Her story is inconsistent in that she had to have been on the island prior to the Purge
. The Dharma Initiative
was active on the island until December 19, 1992, the day which the Purge
occurred. This means that Danielle cohabited the island with the Dharma Initiative
for about 4 years. It's also not explained how she survived the toxic gas attack
that struck the island when The Others destroyed DHARMA.
