Is Ari's route finished? I reached the point where she was going to teleport some teams and then it took me back to the main menu. I think the last words on my screen before it went to the menu were "and jumped"?
Yes, that is how his route ends. There's really no need for further story.
They are preparing for a mission, demonstrating Morgan has settled into her role. She teleports them away to go do the mission. The reader doesn't follow along because the story is done. Morgan is moving on and accepting her life. All the plot points are wrapped up by then. So that's the final line.
The credits should play there but it's very easy to skip them if you click an extra time.
