We need to stop jumping to conclusion and honestly I agree with Reborn. Chill. Flower. I think you're wrong too.
First,
@Flower why do you think Light would use a kill? No where in the Unseen King's wiki does it say he can kill someone at night.
Second, why are you so sure that Beta has to be Assasin? I mean I am considering it a possibility but there is nothing from what you told me that is convincing.
Also I'm not sure if you understand yet but Queen isn't scum. Literally, Drago confirmed it and deducing anything from the reasons of the mistake would fall into angleshooting.
Finally, I know what you are trying to say about Marimo but I heavily disagree.
