However, they don't reveal the full extent of Hamlet's knowledge about the murder of his father or his intention to expose Claudius's guilt. They are simply reporting what they observe, and they are unsure of the reasons behind Hamlet's behavior.
It is important to note that Rosencrantz and Guildenstern are not completely truthful in their report. They purposely downplay Hamlet's suspicions about Claudius and try to portray him as simply mad. This is because they have been ordered by Claudius to keep an eye on Hamlet and to report back on his every move.
Here is a breakdown of their report:
* Hamlet's appearance and demeanor: Rosencrantz and Guildenstern describe Hamlet as "melancholy" and "distemper'd." They mention that he appears "unnatural" and "absent."
* Hamlet's behavior: They mention Hamlet's tendency to "muse," "think," and "talk to himself." They also mention that he "paces up and down" and "walks alone."
* Hamlet's interactions with others: Rosencrantz and Guildenstern report that Hamlet seems to be avoiding the company of others, and when he does interact with them, he does so in a "strange" and "unpleasant" way.
By reporting these observations to Claudius and Gertrude, Rosencrantz and Guildenstern effectively become pawns in Claudius's plot to control Hamlet. Their report serves to mislead the king and queen about the true nature of Hamlet's condition and to further their own agendas.
