Click to see Spoiler:I had been assuming that the rest of the tailie's group was dead. I guess that group wandering in the jungle could be survivors ( these children?) who are captives of the Others. Like Walt. That would tie in with my theory on why they kidnapped Claire - they wanted the baby because they want children. When Charlie killed Ethan, they decided it was too dangerous to pursue at that time and to go for Walt instead - they could try again for the baby later.
So that is definitely not it - since I am so often wrong. But it sure is fun to speculate.
