They guy who took over Christina's shift wasn't too bright. He looked straight at the error panel, and went "All's well!"

So with all of CB's infiltrating intelligence, they didn't pick up anything about this surprise attack. Guess I'll add secrecy to HLR's awesomeness, or maybe just Sergei's. So the incident was Sumeragi's failure. They got me good. Sumeragi's still one of the top strategists to me in the series, but I always thought they talked about her and that incident in a positive way. Now we see why the professor and Billy were worried about her thoughts of it. She probably caused a catastrophe of some nature, and was mentally shocked by it for some time.

And if you thought one Haro was good..... meet the siblings!

@Ryllharu: thanks for the tip.
