Cassian's words to their daughter only serve to make Jyn feel worse about herself because she is supposed to be there for her daughter and she's not. He doesn't even know what he's done, because he thinks he's done something at all. A lack of feelings isn't a crime.

She wouldn't like her either.

She can't linger by the door anymore so she pushes it open, striding in purposefully. She ignores the way she no doubt looks like she was crying, face drawn and pale as she sits down by his knees, holding her hands out for her daughter. "Keep talking, I don't want her fussing while I feed her, she'll only make herself sick."
