Yes, it's alarming that the Horizon is being weird. But Nadine's a lot more interested in being inside (essentially) an actual spaceship. She has plenty of experience with the Horizon being weird, but none with spaceships. And it isn't as though they can do anything about the Horizon, and she's here now.
