How does cracking the vault of the Elmore bank affect Jimmy Valentine

Most of Mr. Adams’ family and close friends attend the unveiling of the new safe ceremony at Elmore bank. Jimmy, being Annabel Adams’ fiancé, also attends the ceremony. Later on, he plans to travel to Little Rock to run a few errands. He carries his suitcase of safecracking tools which he plans to give away to an old friend at Little Rock. When Annabel’s niece Agatha is accidentally locked in the new vault, Jimmy is forced to crack it open, thereby blowing up his cover of innocence.
Cracking the vault of Elmore bank forces Jimmy to show his safecracking skills to the, until then, unsuspecting public. Afterwards, he walks away without a word to anybody. When he meets Ben Price at the door of the bank, on his way out, Jimmy greets him and submits to his authority. He thinks that Ben Price is going to arrest him, and is kind of resigned to this possibility. However, Ben lets him go. After cracking the safe, Jimmy thinks that he has lost everything, even the love of his life Annabel. This is why he asks Annabel to give him the rose on her dress before cracking the safe. The rose will be a souvenir of sorts. By cracking the safe, he has exhibited great selflessness and a caring for other people. Clearly, his love for Annabel has motivated him to turn a new leaf.
