Ritsuko puts the coffee down and speaks with a sigh, in a tired, helpless way.
RITSUKO:“Or what appears to be it, anyway. But we have no idea how it works.”
Reichu: Sounds like all of Doctor Katsuragi's work was for naught.
Tsukaji: So they do not have any idea how angel's power source works and few months later they can mass produce it? That is some fast researching! They do not even know excatly what material angels are at this point.
NemZ: ...or perhaps Ritsuko isn't on the need-to-know list for that data. It probably isn't even supposed to still exist, what with Gendo's last minute escape from Antarctica and all.
