Over the course of three hours, Cassie did everything possible to help Tee get better however his condition kept getting worse. The best thing Cassie could do is give Tee a painless death using seditives. After three hours Cassandra realised there was nothing else she could do, he had been poisoned by something that couldn't be cured on this ship. Best thing she could do now was to call the crew to the infirmary so they could be with him as he dies.
Make love, not toast.
