User blog comment:GeorgePowell/How do you think Mass Effect 3 will end?/@comment-24.163.53.146-20110708192450

So far my theories include the star near Haestrom that Tali was investigating. Something is causing it to age too fast and become unstable. I will be disappointed if this doesn't play some role in ME3. The other theory is pieced together from plot points scattered through out the first two games. The Reapers think themselves eternal and it's not surprising considering how long they've been around. However, if EDI is correct that the Reapers "reproduce" by taking in new genetic material and reforming themselves after the race they take over, then there is another possibility. EDI also theorizes that the Reapers tried to make a Prothean Reaper and failed so they repurposed them as slaves. So consider that the Reapers have gone longer then they've ever had to go without fresh organic material. It's possible the Reapers are weakening and near a state of genetic "death" because their organic parts are simply wearing out. If true it's a weakness Shepard would be able to exploit.
