Currently there's 5 routes: Anders, Gil, Lars, Mark, and Parker. There are a couple of game-overs (like if you don't make any good choices on day 1, or if you don't go after Mark on a certain point in his route), but otherwise there aren't any endings yet.
Episodes are scenarios from another character's pov. Lars and Mark both have an episode currently, you can play them by clicking their heads in the bottom left of the main menu.
