So I just finished reading Uprising, and, having played through ME:A, I feel that whether the Nexus found hazards in Andromeda or not something bad was going to happen. Given that Sloane, with her checkered past and lack of position in the chain of command, was literally the last one awake on the Nexus, I'm betting that she was the designated fall guy. If (the Benefactor?) hadn't found the Scourge or some other plausible mass casualty/destruction accident, then there would've bombings or something and Sloane would've been the scapegoat, as she eventually was.💔
Of course this assumes that the Nexus was intentionally crashed into the Scourge cause/to cover up Jien Garson's murder as well as any other targets in the Initiative and any other activities being carried out. There were huge amounts of equipment, supplies, and materials that were counted as missing or destroyed after the crash, which could have been stolen after all. Sloane did note that the destruction of many of the Nexus' core systems did seem almost surgical and could have been sabotage. 🤔
We do know that Jien must have been targeted by at least 1 individual awake before the Scourge disaster, although we don't know how many or how long they had been awake. To be able to properly set up an "accident" like this they would probably need to be awake a few months or a year early.🤔
