Charles is about to perform some major surgery. A scalp resection and reconstruction plus a highly experimental endoscopic brain surgery. This brain surgery technique is only using in war and he is one of only three neurosurgeons on Earth that knows how to use this tool. First he took his scalpel and performed the scalp resection. He was glad to see blood in the OR again. Then came the hard part we was going to an endoscopic brain biopsy. Getting samples from the frontal and temporal lobe was effortless. Then using the super thing but sharp surgical cable he drilled through the skull and did a full 180 around the skull space finally able to get to parietal and occipital lobe samples. Then then used the tool to seal up cracks and wounds. Sadie is going to need about 5 weeks of healing.
Charles placed the samples in sterile containers ready for further use. Then he discarded his surgical equipment. A successful survey like usual.
