I do not have a night action, Ifrit. Why do you ask?

I was afraid that Doomtrain would turn out to be a strange or unknown role like that. In my opinion, it gives us hardly any insight into how Titan's night action works. According to Titan, his result on investigating Doomtrain was Insane. But what does that mean?!

Ifrit, if the Town's strategy includes not asking Titan to divulge his night action targets and results, who else can we ask? If the roleclaims thus far are true, then you and Carbuncle also have night actions. Are we at liberty to inquire what they did last night?

Going back to read other posts that were posted just now while writing this.
