Was saving the last Rachni a terrible idea?
In the cave in Mass Effect 3, I just couldn't kill the last Rachni. Plus she said she would help us defeat the Reapers. I set her free and left, and when I got back to my ship I had a couple remarks about it. That hologram dude (his name escapes me at the moment) said he wasn't sure of a Rachni ally was a good idea. Then I got was I assume was an angry email from the Krogan Wreav. Has anyone made the decision to save her? Does she fulfill her promise to help defeat the Reapers or was it a lie?
