How does Jim react to the news about Antonia?

Lena mentions Tony, and Jim is eager to hear about her. According to Lena, Tony is now Mrs. Gardener's housekeeper, has reconciled with the Harlings, and is engaged to Larry Donovan, whom she adores. Jim says he doesn't like Larry Donovan and unself-consciously remarks that he should go back to Black Hawk to look after Ántonia.
