At the moment she was cleaning the wound mainly to get a better look at the damage, unseen problems could always go untreated due to severe obstruction by blood. Noboyuki looked to be drunk enough for her to start picking out the bone. 

Eskar, while being one of the most advanced civilizations in that world, they were still way behind the standards Noboyuki was used to. At the very least, medical advancement had an emphasis on battlefield medicine, obviously brought about by the war with the demons, as well as with other human kingdoms even. Rena carefully used a primitive pair of tweezers, cast iron without the precision of machined steel. The bone clattered on the floor, one due to the lack of tables, and two the concept of replacing the pieces back to the proper place, didn't exist. 

She, needless to say, was covered in blood splatterings, Rena didn't express any complaints anyway. "You know... I'm a traveler, I never told you that, well don't think I've had. As a traveler I love learning by worldly experience, and well... as far as journeys go, I have never regretted this one even once."

"Don't beat yourself up, it was a chance encounter with Jonghua, and chance gets the best of all, it is not your fault."
