I wondered if Valerian had talked about psi emitters since becoming Emperor. There might even have been an apology.

If psi emitters are a big secret, then the Dominion of Man attacks make more sense. However, people know about them (now, anyway) so one wonders if anyone was suspicious. Of course, when Nova checks in, I expect Valerian to start talking about emitters and quickly.

I wonder if the Psi Disruptor was a big secret. Certainly it was a surprise to Kerrigan, but that was something a lot of military people would have known about, and it was based on psi emitter technology.
