What's with him

Who: Cerebrums, anyone else in the medi-bay
Where: Guess
The Cerebrums watched as Keto stormed out of the medi-bay. "Is your
Keto always like this?" Cerebrum-1 asked BD Cerebrum.
"Nah, that was hardly anything. His face wasn't as red as it usually
gets when things like this happen," BD Cerebrum replied.
"What sort of things get him really mad?" Cerebrum-5 asked, looking
up from a large textbook of psychiatry.
"Oh, you'll probably see him really mad when he finds out that I've
just drained the medical department's budget dry with these orders of
psychiatric equipment," said BD Cerebrum, "Heck, he might even drop
dead on the spot."
