Ok, well... I've posted something of this nature before, and it kinda got tossed aside. However, I will again point out the short version of why Vudu is potentially the most strongly-hinted-at mafia remaining.
1- Transfiguration
2- His own bio states his grades are poor, and there are several references to botched spells as well as one of the mafia stating from hit 1 I believe, that...
Well an owl looks like a bit of a trick according to this book and….
In the same vein, there's this, from the 4th hit on Namilah -
At a loss for something clever to cast on, what was obviously a powerful wizard in disguise, one of the others shoved their wand up the other nostril.
These are further evidence that one of the mafia is perhaps not the crunchiest cookie in the box.
3- we've all noted the references to toads in mine and Vudu's bios. Hooray yippee.
4- There's the bleedin' obvious clue from the 6th mafia hit, wherein the one spell Vudu is likely to actually cast well is paralleled because he HAS THE TOY in his satchel... the target was chased with a flying broomstick... and Vudu, miraculously, happens to have a little bitty toy broomstick that flies when controlled by his wand in his pack.
There's more against him, you can read the other /ooc thread from two days ago I think. The fact of the matter is, although I see hints pointing at other people, I don't see as much pointing to any one person as I see pointing to Vudu. I'm not saying I can't be convinced that he's innocent, or that someone else is guiltier, but I'm saying that the evidence that has been presented so far against others doesn't compare to the fact that well over half of Vudu's admittedly small bio has been touched on (in some points pounded with a 2x4) from day 1.
And I have yet to see a convincing argument to persuade me that I am wrong on these points... aside from 'the toad thing is in my bio because my mom said it once' or 'Mai wouldn't make me a townie on my first game.'
Huh... uh...... yes she would. :P
