He does not allude to Pyrrhus except when reciting a speech from a play he remembered, a play in which Aeneas is describing the fall of Troy to Dido, queen of Carthage. Aeneas talks about how Pyrrhus killed Priam, the Trojan king, and in the course of reciting the speech he mentions Pyrrhus by name four times. The Player then continues the speech and Hamlet never mentions Pyrrhus again. Act II Scene 2 of Hamlet is immensely long, about 600 lines. For Hamlet to allude to Pyrrhus in a short 14-line speech hardly constitutes alluding to him "throughout the scene". As to why Hamlet brings Pyrrhus up at all, Pyrrhus, otherwise known as Neoptolemos, was the son of Achilles who was avenging his father's death at the hands of the Trojans by killing Priam. His situation therefore has some parallels to Hamlet's.
