It has been awhile since we've last spoken, Paixao. I hope you will accept this gift to make up for my absence. Read closely, and think on this knowledge well.
To understand how the heart works, one must comprehend its balance and what happens when that balance is lost. How does it function with an abundance of darkness? Of Light?
How much until it is thrown over the edge, to a point of no return?
Each heart reacts differently - should they not all operate the same? How are we able to understand anything if our subjects are not on the same controlled level? I wonder, is it possible to reshape a person's heart, so that then we will be able to do our testing properly?
PROJECT F - EXPERIMENT NO. 1
SPECIMEN DESIGNATION: Laharl
PROCEDURE: Injections of darkness, followed by a single injection of pure light.
RESULTS: As a creature of darkness, the subject was able to accept large amounts of darkness, during which he began to take on the physical traits of a common Heartless (glowing eyes, visible and palpable aura of darkness). He reacted poorly to the injection of light, however, and rather forcefully escaped from the laboratory.
CONCLUSIONS: Like accepts like. Creature of darkness may not be able to handle light and vice-versa.
UNANSWERED QUESTIONS: Whether the light acted as a catalyst against darkness injected or against natural darkness.
POSSIBLE FUTURE EXPERIMENTS: Injections either entirely of light or darkness.
PROJECT E - EXPERIMENT NO. 6
SPECIMEN DESIGNATION: Zidane Tribal
PROCEDURE: Injections of darkness.
RESULTS: Subject entered injured and was revived with potion before injections, which may have affected results. Subject was completely unable to assimilate any darkness and instead gained powers not unlike those of the Heartless.
CONCLUSIONS: Creatures of light do not react well to darkness. Weaker hearts may not stand up to darkness well.
UNANSWERED QUESTIONS: To what extent the injury and potion affected results (if at all), Strength of subject's heart to begin with, Amount of darkness needed to make subject lose his heart completely.
POSSIBLE FUTURE EXPERIMENTS: Further injections of darkness.
