my thoughts are that from the time we saw little Annie in "the man behind the curtain" to now, she has lived on the island the whole time hiding. i don't think that ben or anyone else knows this. Ben most likely thinks she died along with everyone else in the Dharma Initiative. i think that she has been living in the island's volcano(that's right) and has been hiding to avoid getting captured by the MIB. i think it will show her coming out of her home in the finale and confronting the mib along with walt and vincent(again, that's right). i know that this is kind of far-fetched but its my theory.
