Speaking of Hauser, we might as well shine a light on this mysterious-bordering-on-shady individual. We first meet Hauser during the investigation into the aforementioned Tiller's death. He claims to be an FBI agent, but eventually learn he's had a vested interest in the mysterious disappearances at Altcatraz for almost 50 years, building a top secret task squad and a high tech command center to hunt down The Sixty-Three's. While he earns the trust of Doc and Rebecca Madsen (Sarah Jones), behind the scenes, it doesn't seem Hauser's on the up-and-up. Watch this guy, we're guessing we're gonna learn a lot about this guy as the series progresses.
