Despite the fact that Zandik is a fairly attractive young man, it was obvious that he didn't pay much attention to some of his hygiene needs. He is constantly irritable and uncommunicative, he is not bothered by idle talk and love. He is preoccupied with science and his "delusional" ideas.
He lives in a dormitory and his roommate has complained about the noise many times, because Zandik works at night. Either he is busy building mechanisms or "picking at" living organisms.
