Jason McCallister is the brother of Senator Robert McCallister (Rob Lowe). His presence in the storyline of Brothers and Sisters is relatively fleeting, both in referential contexts and in the character's actual presence (a total run of 5 episodes). We first meet the character in Episode 1.19 Game Night (aired 15 April, 2007) when Kitty (Calista Flockhart) sets him up on a blind date with her brother, Kevin (Matthew Rhys). Jason and Kevin begin a romantic relationship, but eventually break-up. Jason is a Christian minister and leaves to perform missionary work abroad. After leaving, the character has received only passing references in subsequent episodes.
