So, what do we know about Mei? She worked in OW as climatologist on Watchpoint Antarctica. Then there was an accident and the scientists decided to immerse themselves in cryostasis until they were rescued. But the help didn’t come and after 9 years, Mei wakes up and turns out to be the only survivor. She fixes the antenna and catches the signal from Winston. After that Mei decides to get out on her own - just with ski. Maybe it was so, maybe.
But maybe not. Let’s think about this. If Mei could get out of the Watchpoint alone, could all scientists have left together? Maybe, maybe. If Mei could fix the radiostation alone, could she do it with the help of other scientists? Maybe, maybe. Why didn’t Overwatch send anyone to his scientists? After all, it was 9 years ago, even before the “Retribution”, so there was no decline of the organization. Maybe the radiostation worked and on the contrary sent signals that everything is in order? Maybe, maybe. Finally, why did only Mei survive, why were the rest of the cameras was turned off? Maybe someone turned them off specially? Or programmed one robot to turn them off?
Maybe. Mei-be…
