Think of it this way, the researchers are considered men of science, which is also what 049 considers himself.
He has a liking for other men of science and would like to engage in conversation with them.
More so if a breach happens it’s a defcon 4 as it’s a Euclid breach so they wouldn’t have to go to bunks anyway as that procedure is only carried out for defcon 3 or lower. It’s hard enough for research to test on stuff without being interrupted by d class, GOI, and other stuff. And him being breached does not automatically mean all his colleagues have the pestilence, that’s not how breaches work.
