when jim came home in the summer and went to the photographers, what did he see there and how did it affect him?

He sees a picture of baby Antonia,

`That's Tony Shimerda's baby. You remember her; she used to be the Harlings' Tony. Too bad! She seems proud of the baby, though; wouldn't hear to a cheap frame for the picture. I expect her brother will be in for it Saturday.'

Jim has an intense feeling to see Antonia again.
