We finally get a Chris-centric episode as we dive into her background. There's nothing wrong with side-quest in order to care about Chris as a character, but her motivation is something I find predictable. Chris also has done very few scenes that allows the Lazarus members to be emotionally attached to her. The little information they know about her doesn't allow assumption to be made by the characters nor the audience for us to be shock by the revelation of her past. Outside of that, the rescue mission makes the episode fun and interesting.
