Still missing my brother...
See, I didn't take him for being panicky. To me, he just seemed to be morosely strategizing. The utter lack of description for whatever is coming just has me thinking they don't know. I really don't like when writers do this (purposely avoid explanation for the big reveal), because people don't talk like this for extended periods of time.
Although solicits tell us that something very evil has come into the world from AoX. This could be what he's talking about, but I'm not sure he would know about that. Depends on when this is supposed to be, I guess.
