What trick of Penelope impresses Odysseus

Athena influences Penelope to make an appearance before the suitors, first beautifying her through her powers. Penelope comes downstairs and privately rebukes Telemakhos for allowing such abuse of the stranger. He tells her he had no option with the suitors and informs her of the beggar's one-sided fight with Iros. She laments Odysseus' absence and recalls his directions when he departed for Troy to remarry once Telemakhos has grown up, but she finds the suitors despicable. Odysseus happily hears this, as does Antinoos, who insists that they will not leave until she marries one of them. The suitors bring her gifts, and she returns upstairs with them.
