What is going on when telemakhos and peisistratos come to sparta

Menelaus set sail for Greece immediately, while Agamemnon decided to wait a day and continue sacrificing on the shores of Troy. Nestor went with Menelaus, while Odysseus stayed with Agamemnon, and he has heard no news of Odysseus. He says that he can only pray that Athena will show Telemachus the kindness that she showed Odysseus. He adds that he has heard that suitors have taken over the prince’s house in Ithaca and that he hopes that Telemachus will achieve the renown in defense of his father that Orestes, son of Agamemnon, won in defense of his father.
