Great potion which is fully justified and almost poetic in its final results. Taken to quell the flames of emotion, when they can be subdued no longer it bursts into flames. Awesome!
Since most have already taken the potion, the bursting into flames of their neighbors may not bother them too much. Until finally their own fear of it may overtake them and they burst into flames. Crazy countryside where everybody is a ticking time bomb with an unknown amount of time on the clock. Crazy.
