Scarlet had indeed forgotten that he'd left his vote on Jorrick. Unfortunately, while Karis had some good points, it would also be noted that in that past life, he had been fairly Village read and could afford to make things like that without seeming too suspicious. This game, it would seem as if it would be foolhardy to simply claim it wasn't distancing at such an early phase.
The terms of the vote in Scarlet's opinion wrote clearly, "Vote for who you want to die." Scarlet hadn't wanted anyone to die yet.
