"I thought..." Prim starts, but she doesn't know how to finish it. She scrubs at her eyes, starts making sure she has her things, moves towards the door. The words find her a second later. "I thought you might be happy with just me. I didn't know I should tell you not to do that."

Her mouth tugs as if in spasm. "I have to go," she says, voice breaking. "I have to go." Her hand finds the doorknob and turns, letting her stumble out into the hall. She starts running, and she doesn't stop until she's on a train, knees pulled up to her chest, sobbing.
