Unlike Nick, Rey can't run a full system scan to see what's wrong with her. That would have defeated the whole purpose of allowing her to often live without the knowledge that she wasn't human. Whatever the damage is, though, she can sense it in her chest. Nothing like a collapsed lung or major organ damage, but still not something that she can simply ignore. And yet...

"Will be fine." She shakes her head, letting out a shaky exhale. "Have survived worse than this. Just need to rest."

After the beatings she had taken and several blows to the head too many, sleep is sadly the last thing she should be doing.
