For the rest of the time that he was doing the duty that he had signed up for, Daneel was pretty absent-minded. Again and again, he couldn't help but think back to that image where the city he had grown up in had been burning, with hundreds of thousands of people being massacred by the Mad Doctor who, for some reason, was finding a lot of joy in doing that act.
The head healer got more and more irritated with him as being absent-minded meant that he was also quite clumsy, but Daneel didn't care. He had already seen everything that he wanted to, and there would be no coming back here anyway.
The moment he went back to his dorm, Daneel tried to take a deep breath to calm himself, and when he finally managed to do so after a few minutes, he tried to focus on the other 'lights' in that space with the hope that he could find something else that he could use in the situation.
