Szayel shrugged both of his shoulders, lightly. "I admire the man's work," he began, a phrase which wouldn't normally have left his mouth, but Shinra's SOLDIERs were more than a little influential in the world of bioweapon engineering, "but you have to admit he lacks a certain tact. I doubt all his specimens consented to be experimented on." Some had, certainly, the Thirds and Seconds, and possibly the Firsts that were not Sephiroth, as if anyone remembered their names, but Sephiroth, it seemed, had grown up an experiment and knew nothing else. Kadaj had been destined for the same course in life, and Szayel knew that in among Shinra's files there would be testing on illegally obtained specimens, some of them licensed species. The controversy brewing when Hojo had 'died' had been regarding the manufacture of chimaera, a controversy which combined licensed species, and illegal alchemy.

He looked at Kadaj. "He's used to hearing 'no' from his specimens, as well as threats, is my point." He gave Kadaj a nasty smirk, folding his arms across his chest. "If he acts like he doesn't hear the objections from myself and other Arrancar, don't expect him to be put off by one of your little tantrums."
