(First Responder!AU) Moving to Los Angeles and living with your brother, Thor, was never part of your plan nor was being a 9-1-1 dispatcher, but plans change when you are faced with your own emergencies. In your case, it was leaving behind a relationship that wasn't as perfect as it seemed. Will this be the fresh start you were hoping for or will your past find a way to catch up with you?
