Sean Carter remembered an incident from when they were still abroad. His boss had been caught in a similar, unidentified attack. During the confrontation, his boss's old affliction had flared up. He hadn't been able to take his medication immediately, and the unsuppressed virus had multiplied rapidly within his body, causing his system to break down and waste away quickly. Even after taking a large dose of the medicine later, he was still severely weakened. He had to recuperate in secret for nearly a month before he was fully recovered.
This time was remarkably similar to the last. By the time Sean Carter received Aurora Sterling's call from the parking garage, his boss had already been suffering for a while. By the time he dealt with the attackers and found his boss and the others, even more time had passed.
