The one thing everyone knows is that the Reapers are systematic. They kill. They take. They kill again. They take more. Systems. Planets. Lives. The ground they walk on. If it breathes, if it can think for itself, it's their next target. Not a matter of if. Not a question of maybe. Only when. They do everything with precision. So why, when the Reapers are holding the gun to the Citadel's head, do they not pull the trigger and yet instead run into deep space? It's a question that Shepard has to answer before the Reapers make an encore appearance. DISCLAIMER: I own nothing of Halo Or Mass Effect. They to 343 and Bioware respectively.
