As one picture is not really enough to describe this episode, we shall use multiple pictures.
This episode starts out with Sara getting ready for her birthday party.
However, Mr. Barrow arrives at the Seminary with some news.
After he tells Miss Minchin what he knows, Miss Minchin abruptly changes her behavior, as she literally abuses Becky for overhearing the conversation.
Then, Miss Minchin goes to the dining room where she brusquely gives Sara the news that Mr. Barrow told her. From here on out, Sara's life will never be the same.
