Thank you for the opportunity to help you with your question!
Ian stole money from an armored car and then asked his friend to hide him. It is morally right to turn Ian in, because even if she is loyal to him, it is doing the right thing. Her loyalty for her friend as well as her own ethics could tell her that he needs help telling between right and wrong, and turning him in will help see right from wrong.
An excess of loyalty would come from not turning in her friend; this goes beyond loyalty. It goes beyond loyalty once one crosses a line of what is morally right or wrong.
In summary, if she believes that stealing is wrong and knows her friend needs help, she is staying loyal to him by helping him. At the end of the day, being loyal to someone is having an allegiance to someone, or staying by their side. She 'stays by his side' is she turns him in to help him rediscover ethics and morals.Please let me know if you need any clarification. I'm always happy to answer your questions.
