>>52408374I personally think scarlet has the better interpretation, as you can complete the paradox loop.
Sada finds weird robot in area zero, it has instructions and memories of something, the team reverse engineers it based on the information from the robot. Creates time machine, Sada creates ai based on the robot they find, chooses to make it a copy of themselves, thus giving the ai a copy of the time machine blueprints and memories. Story occurs. Sada Ai, in order to shut down the time machine for "good" sends themselves into the past, to then be dug up later in area zero, completing the paradox loop.
