This Prothean was one that was never captured by the Reapers and never genetically altered. By the time the Reapers altered and enchanced the Collectors, they were already the result of several cloned generations of indoctrination before they couldnt do basic tasks, so the Reapers altered them. This guys has never been through that, else he wouldnt be able to talk or move.
