*At the infirmary, a test is run on Dr. Carmack’s unusual black blood. The result reads: blood group cannot be identified. When the test is run again, the same result comes up. Duke and Sam are so stunned and distract by the unusual test results, they fail to see Dr. Carmack’s escape. When they turn around, Dr. Carmack’s restraints are empty. All that remains on the gurney is a blood-stained sheet.
