I don't think that will be necessary, Edgeworth. See, there's a rather glaring hole in the evidence:
The greatest tissue damage occurred to the brain, with some lesser damaging to the stomach. There are two primary ways for poison to reach the brain: Through the circulatory system, via direct injection into the bloodstream or via inhalation. We know for a fact that this poison, however, was ingested. In order for the poison to reach her brain it would first have to pass through her digestive system. This means it would take some time for the poison to take effect. It would take even longer considering the poison was laced into food.
This leads to another obvious contradiction: You claim that the poison is a silent killer, and beyond that, no one claims that the victim displayed any strange signs of discomfort. Considering the damage to her stomach, this is odd, as one of two things should have happened. The body's default reaction to ingesting potentially harmful substances is to induce vomiting. Even without this particular symptom, the poison damaged the lining of her stomach. Considering that she ingested the poison with food, her stomach would have been in full swing. Damage to the lining of the stomach while it was pumping acid around would have caused ulceration, and the stomach digesting itself is not a pleasant sensation. So why did neither of these situations occur?
The victim should not have died as quickly as she did from an ingested poison, and she experienced no symptoms from the damage to her stomach. The conclusion should be quite obvious: The poison that damaged Octavia's brain could not have come from Ms. Bon Bon or Ms. Scratch, because the real murder occurred well in advance, and this is when the neurotoxin was administered!
This entire case has been investigated from the wrong time frame!
