"Something you don't know?" Eda's double looks thoughtful--yeah, that was clearly sarcasm, but now she's thinking about what could actually be useful.

"Well, for one... that one friend she does have is definitely the way to get to her." She's pretty sure the real Eda hasn't told Cortana much about Raine--or told anyone much, really. The rumors are certainly flying with her chasing them around the compound, but the woman isn't exactly elaborating on what happened there.

While it was technically an exaggeration to say she has no other friends here, the woman isn't exactly great at opening up to them.
