The word that could fit the gap is definitely a possessive pronoun such as their, used because it refers to the previous pronoun them
Is this "All Quiet on the Western Front"?
Hi!
The statement that best explains this is:
The allusion highlights ideas that relate to the murder of King Hamlet.
We see that in the myth of the Trojan War, Pyrrhus eventually kills Priam (the King of Troy). Pyrrhus was elated to have done this deed, and that to with Priam's wife, Hecuba, beholding the sight. Priam had caused the war that had eventually resulted in he death of Pyrrhus's father, Achilles, and so by killing him, Pyrrhus was successful in avenging his father.
The reason Hamlet alludes as this particular story is to establish that his motive is similar to that of Pyrrhus's in that Hamlet seeks to avenge the death of his father by killing the King, Claudius, in the presence of his own mother, and Claudius's wife, Gertrude.
So just to be clear, the hints at the following roles:
Hamlet as Pyrrhus
Claudius as Priam
Gertrude as Hecuba
