"Kudo-kun," Haibara said sharply, "At this rate my prognosis is that you will develop complete immunity before I can create a permanent antidote. You cannot keep using the temporary antidotes as your main plan to get out of trouble. I would hesitate to give you an antidote for even life-threatening situations, considering how regularly you seem to run straight into them instead of exercising what little self-preservation you have."
The detective was wide-eyed, "How…how long…?"
"If you continue to use the temporary antidotes at your current rate, I expect you will become completely immune in less than a year."
A/N: Prompt word: prognosis- a forecasting of the probable course and outcome of a disease, especially of the chances of recovery
