Final answer:
The provided excerpts do not offer direct insight into Rosencrantz's feelings after his conversation with the king and queen in 'Hamlet,' thus preventing an accurate analysis of his emotional change.
Step-by-step explanation:
The student's question addresses the changes in Rosencrantz's feelings after his conversation with the king and queen in the play Hamlet. To determine Rosencrantz's feelings, we must refer to the text of the play itself. However, the provided excerpts do not directly correspond to Rosencrantz's character or his interactions with the king and queen. Subsequently, without the relevant passage from Hamlet, it is not possible to provide a definitive answer.
Generally, in literature, characters may experience a range of emotions after an interaction with authority figures, which might include excitement, fear, reluctance, or confusion dependent on the context and narrative. An accurate response would require a review of the specific conversation between Rosencrantz, the king, and the queen within Shakespeare's work.
