Kaitlyn Alister is the younger sister of Drew Alister. She served at the same time as Drew did. But, during their tour, Kaitlyn was kidnapped and held hostage. Drew did everything he could to find her and get her back. But, when his tour ended, he had to go back home. It killed him to leave his sister behind, but part of him knew that there was a very good chance that she was dead. What happens when he finds out that his sister is alive. Face claim: Elizabeth Olsen (This idea is not my own. I got this idea from Grey's Anatomy, but I thought it would be interesting to have a storyline like this in this show. This takes place before season 1.)
