Some good thinking here, but some very broad assumptions and drawing a couple of long bows. Vex 5 also records all of Maya's experiences with the machine, which means we can assume it didn't kill her. Those events also take place years after the events on Venus, so very difficult to determine if she was human or Exo here without some more timeline detail, and more importantly, detail of how these human consciousnesses were built into Exo frames. Her attitude in cutscenes is subjective but she appears very critical and analytical. Happy to run in the face of danger rather than bad assing her way through a wave of enemies. It is clear that maya has a strong relationship with the FWC, it is probable that her work led to its foundation. The Exo stranger 2 card also takes the same format as the journal maya started in vex 5. Exo 2 seems to suggest she is searching for someone or something capable of taking the fight to the darkness, possibly why she engaged with us in the first place.
