Cassian is not an emotional creature, he's always been so much better at concealing his emotions than she is and so the tiniest hint of emotion from him is huge. It makes her feel a little ill and a little hopeful at the same time. She always used to get such a giddy rush from poking cracks in his facade, pulling smiles and laughter from him when they were hiding in her cramped bunk or at more inappropriate times like in the middle of the mess hall or tucked into a corner of the hanger or sitting in the pilot's seat of the U-Wing... rein it in, Erso.

At least he isn't indifferent.

She doesn't point out any of that, knowing better and somehow finding the self-control to not ask him outright if he hates her. "Yeah. I'll go wherever you want me to go."
