Fea dear, if it was likely you were a Critic, I would actually try and save you. That way the Lovers would have a Critic target to take a shot at. There would be no pressing reason to be rid of you today.
Unfortunately, the scenario that appears most likely is Fea=Walter. And so logically we should lynch you, as it wouldn't be a good idea to risk yet another spying mission.
So really, if you don't want to be lynched today, admit to or lie about being a Critic.
