I voted Velvet because I'm getting a strong scum read from them and since I expect to be dead tonight going after someone I've confirmed to be mafia who is just the role blocker isn't that important to me.

And unless I'm mistaken, even if I am night killed my ability should still go off anyway shouldn't it? I suppose that's a question for the host. Will my night action still happen if I'm night killed? And if I'm not night killed I've still effectively removed their role blocker to protect the other roles who can sniff out info if that's how we want to play things.
