Simply put, Sivu and Lock didn't need to write that they were going to the doctor. Arandora wasn't there, Alex was passive, and I was asleep. That left you and Ples, who also could have played the part of his wife going to the doctor. Instead, there was some unnecessary argument with Locken about "it's pointless anyway."
So, for a long time, the option of taking one of the poisoned fruits and complaining about the symptoms caused by this stuff was completely ignored. The fruits may not be called "arche," but maybe the doctor would have seen it and said, "Oh, this is the diarrhea-vomiting mushroom! What the hell are you doing eating this? Here's some activated charcoal, and get out of here, I have lunch."
