See the problem with that is that I'm a redirector. The bigger problem with that is I'm a
random redirector, so I can't choose who to redirect to.
The biggest problem? I can be self-targeting! Which is what I did, 'cause I know I'm town and don't want any badness happening. The only issue I foresaw was if the investigator happ- oh.
If it makes you feel any better, had I not been self-targeting, you would probably not be marked

So you investigated one of the other three, since I also know that the random player chosen to be redirected to can't be the person that targeted me. Which means you're (probably) not lying. Bonus.
Town Special, if you're interested.
I'm not sure if investigating TBF would reveal the Evil role, since technically it isn't "needed" for a TBF/neutral win. I could also argue that an Evil role is required for a town victory, since that's who needs to be eliminated.
