"Overseeing the robots of Dr. Fastolfe's estate, and later Lady Gladia's estate, were certainly part of my duties," Daneel offers, though he's uncertain. "I have also taken charge of situations which have the potential to turn dangerous, when no one else is available. I am not certain that is leadership so much as it is responsibility."

He falls silent for a moment, trying to consider this.

"Perhaps they are not so different. A good leader is responsible for large numbers of people." Daneel's expression is thoughful, puzzled. "My Zeroth Law obliges me to protect humanity. Certainly it is possible that at some point I may find it necessary to assume such a position in order to minimise harm to a great many people. I suspect it may be easier for me to do this if I am under the guise of being human."
