One question comes to my mind, though. People have talked about whether Hammerhead remembers Shepard, but does she remember the stolen data Cerberus encrypted into her? Normally there'd be no connection between her junk DNA and her mind, but there's nothing normal about what Sandstar does to genetics.

Also, is it even relevant now? It's over two centuries old. It'd be like if I had knowledge of troop movements, recognition codes, and black powder recipes from the Prussian Army. It might just be an interesting personality quirk now, rather than something bad guys would potentially pursue her for.
