3. Season 4
An underrated season! Casey gets a lot of the spotlight here, from dealing with the news that Dawson is pregnant to fighting for his life after being kidnapped. The decision proved a smart one, and helped to solidify Casey as one of the show’s core draws.
There isn’t a ton of action or brushes with death in season 4 (the kidnapping notwithstanding), but the show managed to tell engaging emotional arcs without getting mawkish or overly reliant on melodrama. Quality character stuff always gets the job done, and there’s plenty of that here.
