User blog comment:CrackFoxJunior/A way to destroy the Reapers WITHOUT destroying EDI and the geth./@comment-5337704-20120802062535/@comment-99.140.217.58-20120804154202

EDI was created in part by using pieces of Sovereign mixed with the Luna AI. So she's part Reaper. The Geth, If they survive, are infused with the Reaper code. So they would fall under the Red beam's targeting criteria of dropping ALL reaper forces.
