Demon in a bottleMiles has not been this drunk since the show's premiere. He is drinking to numb the pain of Emma's loss, but it isn't really working. However, the news that Neville brings helps Miles focus: Monroe's new plan is to weaponize anthrax!
Father and sonMiles isn't the only one who isn't happy to see Tom. His son, Jason, is also angered by his presence. While Jason chose his path out of compassion, he feels that his father lacks a moral compass. Tom, he argues, will work for anyone -- as long as they make him feel special. Jason's mother almost died from hypothermia during her escape from the city, and Jason isn't exactly pleased to be working with his father.
The dark side of Miles MathesonMiles captures Dr. Camp, who is helping Monroe to weaponize anthrax. Miles tells Camp to switch sides, or his wife and daughter will die. Charlie is shocked by his callousness, and Nora says she's going to transfer to a different unit. Nora thought that Miles had changed, but he's still a monster.
Charlie and Jason later take control of the ship from Miles and Neville, and retrieve Dr. Camp's family. Neville tries to retaliate against Charlie, but Miles intervenes. Miles eventually helps Camp and his family go into hiding, and Nora decides she won't leave Miles, after all.
