[spoiler]I've compiled my 1 post and reply in this thread to make it easier to read[/spoiler] [quote]I wouldn't be surprised to find out if the Exo backstory got more coverage in D2, with a visit to the Deep Stone Crypt (by Humans, Exos, and Awoken) to try and discover the reasoning for their creation and/or logic behind that dream they have. Also, it's my belief that Exos are subjected to periodic memory wipes to prevent their personalities becoming too erratic, eccentric, or even maniacal. Or, similar to why C-3PO's mind was wiped, to prevent them from revealing certain information..I wonder if there's a data bank located [u]in[/u] Deep Stone, or if Deep Stone is a data bank of all Exo memories. They, plus Rasputin's secrets, could hold the key to defeating the Darkness...[/quote] Perhaps the memory resets are intended to keep the fragile human consciousness contained within safe - after all, Exos are still Human in all but external appearance and internal anatomy i.e. they can think and feel as we do.
