Though I admit that that was a good use of your limited resources, it seems like an odd extrapolation to me for a few reasons:
1) My name is taken from the Perry Bible Fellowship comic, Lord Gloom. Though you could obviously drop the "Lord" and be left with the Pokemon Gloom (this IS a Pokemon site, after all), it totally discounts the character that my name is actually based on.
2) Obi never said the smell was specifically "foul", just "strange". That could point to Fishin or m0nkfish (fish are commonly described as smelling funny, you know that I'm sure) as easily as it could to me. Also, given the situation, cookie or cook could be described as smelling funny. It would be odd if you smelled cookies right after a murder, don't you agree?
I'm not trying to indict anyone, just attempting to clear myself before you all attempt to bandwagon me. Bandwagoning with no solid evidence (although this is obviously more evidence than we had on Bioshock) has already cost us a villager.
Also, all this conjecture is based on purely circumstantial evidence; who said Obi was even giving clues in this manner?
