He's hopeful, for just a moment, on the point of explaining the little bit he can and rushing her along home to safety. The hope only last a few seconds before she makes it clear that while she might be a bit more present, she's not quite with him. But if she's asking him for help, then maybe he still has a chance of helping her. The names don't mean anything to him, but without the hostility, maybe he can rely on being vague and quiet and nudge her the right way.

"You're not alone, are you?" he says softly, liking the sound of that, though he doesn't know if it would work on him, and he's just regular paranoid. "Come on, I'll take you home." He regrets that one as soon as it's out of his mouth. He doesn't really know much about Jyn--more than he did, but not much--but he's pretty sure home isn't a concept that works for her any more than for him. Probably less. He tries to look reassuring, but he does it without eye contact or getting anywhere near her, so it's not all that effective.
