There is another mysterious child roaming the island. He is carrying a stick or a spear (like the one Flocke was carving in his stalled camp). The new boy is dressed like the other mystery boys: in old, 1880s clothes of the Others.
When the first blond boy came across Flocke with Sawyer, Flocke was told he could not kill him. Flocke was surprised that Sawyer could see the boy. Flocke ran after him. Initial impression was that this could be a young Jacob.
The second child was a dark skinned, dark haired boy in the temple before Flocke came to destroy it. This boy did not have any speaking parts; and was never seen before or after. It was like no one really noticed him. Initial impression was that it was the soul of a young Sayid or young MIB.
The new child appears older, taller and leaner than the prior two. Again, no speaking parts. Flocke was surprised that Desmond could see this boy.
The pattern of new characters without any explanation can be aggravating or the key to the solution of the island mysteries. These children are not normally "seen" by island residents as Flocke has been surprised that Desmond and Sawyer's reactions. Are they ghosts like Michael? Why would a smoke monster be afraid of ghosts? No, there is something more to these children. They are more important than the Others, and probably more powerful than trapped dead souls (Whispers).
