You are phenotypically identical to Ambrose Cusk and to Kodiak Celius, but you are not they. They were alive in year 2472, when the Coordinated Endeavor launched, but were never on board. Their DNA was extracted during what they thought was a standard full medical examination, then used to create clones of their bodies. Those cloned bodies were then cut or abraded to have the same scars you both remember having.
