- This page refers to the pillar of smoke from "Exodus, Part 1". For the black smoke creature/entity, see the Monster.
Rousseau claimed the same pillar appeared right before the abduction of her daughter, Alex, by the Others, a week after her birth. Because of Rousseau's warning and the appearance of the pillar, the mid-section survivors decided to hide. A small group left on a quest to find dynamite and blow open the Hatch while the rest of the survivors were led to the caves by Sayid. After directing the first group to the dynamite in the Black Rock, Rousseau returned to the beach camp and, in the confusion of their flight, kidnapped Claire's baby.
When Sayid and Charlie set out to bring Claire's baby back, they discovered the origin of the pillar: It turned out to be a brazier, burning an unknown material on the beach. Rousseau appeared and claimed she had heard the whispers saying that "they" were going to take "the boy". She thought that if she brought the baby to them, then they would return her child. Sayid commented that it was odd that there were no footprints of people who lit the fire. It's possible that the Others were able to cover their footprints, since we know that "they don't leave tracks."
Rousseau's statements about the Others are not straightforward. Rousseau used the terms the Others and the whispers interchangeably as if they were the same thing. At the time she took Aaron, she still claimed she had not see an Other as a person on the island.
Sayid also created a pillar of smoke as a signal to Jack, when Jack was leading Walt's rescue party of himself, Kate, Sawyer, Hurley, and Michael in "Live Together, Die Alone". It was visible from both the Pala Ferry dock, as well as Jack's point of view at the capsule dump. According to Sayid's surreptitious ambush plan, he also had intended the Others to see the smoke. The Others eluded the ambush, arriving from the ocean-side in the Galaga to capture the Elizabeth.
Aldo states that he is protecting Kate and Jin from the "big pillar of black smoke that makes a tikka tikka noise and looks pissed off". ("What Kate Does")
