I've never been sure about this thing here. When a Guardian comes back in life, he remembers nothing about his own past. Always found this very intriguing but then... does a Guardian chose his own name after rebirth? Or does he remember it? I know that many Guardians have dreams about their past so, maybe, some of them could dream scenes of their past and ri-discover their names, but what for the others? And what about the Exos? Is the same thing for them?
