Answer: PEARL: Are you the only one who can command him?
RABBI LOW: I don’t know.
Explanation: In these lines, we learn that the characters are interested in commanding the Golem. However, Pearl asks whether Rabbi Low is the only one who can command it. The fact that she asks implies that the Golem tends to follow Rabbi Low's orders, but that it might not correctly follow Pearl's orders. This is an example of foreshadowing.
