A reason -- I would be most eager to hear a decisive reason to vote against someone at this point, even myself. I see no reason not to share it -- if it is convincing, then I will be impressed (and in this case, amazed, as I am most certainly not the last Capulet).
Despite this, I have no reason to suspect Kerri. Again, appealing to the voting record, my question would be to lisar, the only person remaining to never cast an initial Capulet vote: who do you think did it? It's a thin reason, but if we're offering reasons, voting record seems to be a good start.
But before I cast my vote, I will also say that I find it strange that there was such a substantial swing in votes following Remiel's. The last remaining Capulet has a very obvious strategy available to her: to stay in an alliance until the last few rounds. What better place to hide than in a crowd? I believe Remiel, Blythe and Martee to be innocent, and MistressEvelyn is alas departed. So I would wonder who among Ryven, Elina and lisar is the Capulet hiding in the crowd of an alliance? It could even be Kerri, I suppose, in which case, that would be quite the irony.
The only name to appear twice: lisar.
