I also kind of wonder about the source the more I think about it...because during the day cycle, WTF was very sneaky and came out and said she had the light saber but didn't want to use it (admittedly a smart move for a wolf, bc it makes them look good) so why would anyone bother investigating her of all people? That person is either 1) way smarter than me and suspected that she was being sneaky, and of that's the case then kudos! Or 2) a wolf trying to confuse us by revealing to us a wolf that can evade lynching
If it were me and I had been the investigator I would not have gone after someone who admitted they had a death weapon but didn't use it, but maybe I am too trusting of people. Like Devyn and her source, I trusted them 100% when she revealed her info, until Nyanko brought up the possibility of a set up lynching.
