Oh... well, in that case, we have you, me, Rantai, rust, and foulcoon as insane. Either Haneii or animask is sane (we'll never know because we can't tell what their role really does, since it has no response anyway, unless Haneii makes a successful protect).
If what you said is true, this actually clears you from being the killer. It also clears rust. I know I'm not the killer, which leaves either Rantai or foulcoon (or, less likely, Haneii or animask). (Hey, my gut instinct back from day 1 is in there. =_=//)
vote: lie detectI targeted rust45 night 1.
If this turns out to be true, I definitely recommend that Haneii protects you tonight, because there is a 1/2 chance he's a doctor. Now that this has happened, the person at the top of my list is foulcoon again (back to my gut feeling

).
