That is a difficult one. My first guess is, it will be Mueller and her ship. Mueller has become a very tainted captain, which could be one reason to kill her. Another one might be that the characters are indeed spread to several places and it might be a good idea to get rid of one of them so that PAD can concentrate on others that offer more potential and are more important. I really would like to learn about station Bravo and Shelby`s staff!
