Forum:Mass Effect 1 - Question about Ilos (spoilers?)

I am on my first play through of Mass Effect 1 (I know, I'm a little late to the party), but I just realized what might be a considered a plot hole in the story. How did the Protheans know to put their scientists on Ilos into cryogeneic stasis? I understand if they knew the Reapers were coming, but they didn't. By the time they did know, they wouldn't have had time to build the cryopods because they would have to be entering into them at that time. Obviously, them studying the mass relays and making one of their own is fine, but it seems unlikely they would be so completely prepared for a disaster as an invasion by the Reapers. Sorry if this has already been asked, I am just curious. ---RobotBob 07:12, April 19, 2011 (UTC)
