a) V, i, (77-79) "That skull had a tongue in it once could sing once. How the knave jowls it to the ground as if 'twere Cain's jawbone, that did the first murder!"
-Hamlet realizes here that death comes to everyone and he doens't seem as unsettled as the rest of the novel with the thought of death.
b) V, ii, (85-88) "But I am very sorry, good Horatio, That to Laertes I forgot myself, For by the image of my cause I see/ The portraiture of his".
-Hamlet tells Horatio that he shouldn't have had such a bad attitude towards Laertes because they are going through the same type of situations.
c) V, ii, (250-253) "Then Hamlet does it not; Hamlet denies it. Who does it, then? His madness. If't be so, Hamlet is of the faction that is wronged; His madness is poor Hamlet's enemy".
-This is where Hamlet comes to a realization that his "madness" was really his worse enemy all along, not Claudius or anyone else.
