What doesn't make sense to me is 1. how broken Obi's role must be if it's true and 2. how toothache knows all of this.
I understand the whole, sharing info with your allies, but I find it highly suspicous that he has gathered so much information from a variety of sources in such a small amount of time. First, his role as one of the twins grants him knowledge of his other family members, including the 'evil' one, which basically assures Percy's death from the start. Second, the inspector just happens to contact him of all people, who was already suspicous against Obi, with this information. Information, who only proof we have for is his word. Is this not suspicous to anyone else but me?
Edit: I'm not saying that Obi doesn't seem suspicous as well, just that most of the evidence against him has been circumstantial. He brought this upon himself, that much I agree to, but with vulnerabilites so blatant when compared to the other mafias, I'd much rather have good, proveable evidence before killing someone who might not be guilty. The evidene against aamto is pretty similar, but at least with his death, and we know our next course of action. If he dies and he's innocent, Obi must die. If he's guilty, then Obi's innocence is proven. However, Obi's death carries far more wieght with it due to the possibility of him being a mole liek character. It doesn't seem very fair sure, but to me it seems the best coure of action.
