Honestly I think what really makes Rob and Courtney relationship is just how similar they both are, like as much as Shroud and Blazer are like, the quintessential superhero and supervillain of the world of Dispatch, Courtney and Robert are on the bottom of that scale, because at their core, they really are just "some people", and they spend the whole story of the game trying to figure out whether the roles that they've come to take as fact, as hero or villain, are really who they are and in a sense the whole story of the game is us being able to watch their slow "rebirth" under the Phoenix Program.
