One thing that sticks out for me is that Flower was forthcoming with information right away. While I'd prefer for her to not claim like she did, the fact that she presented information and was slightly nervous about it, vibes with her in Death Note. She gave information and talked about her experience in a precious Death Note game and she seemed like she did want to put all her cards on the table right away. While I did later go on to suss her, she obviously was town that game so her doing that at the start of Death Note was a townie move by her. I can't really see what a scum Flower is doing her by admitting she is a mason, especially since if in WS games mason can be town/wolf, she wouldn't know that info (I guess if she's wolf maybe someone told her in the chat). Based off of Death Note and her willingness to be open right off the bat, I'd give Flower a town lean.
