Cop, I understand what you're getting at, but what kind of answer are you expecting? I think both yes and no apply to the Yashur=modkill theory, right?
Look at my position. I wasn't thinking about the Master's version, let's say, but... I expected you, when under suspicion, to immediately start clearing your name if you have information, and if you don't, you wouldn't worry about it. As far as I could tell, the first thing happened – you started actively offering interpretations of the events of the first night, and it seemed like you had information. At the end of the night, you persistently asked me about suspicions, which I interpreted as "Let's combine the pleasant with the useful, I'll visit the newspaper and get information." It wasn't clear why this trick was even possible, but okay, I gave you Yashur.
And in the morning, Yashur was isolated, and... What's the point?
You can't be Dario, you can't be Shendet, you also publicly ruled out Shizuo. If you were someone who might have information about that night, who else could you be?
Okay, even if the Master's interpretation is correct about the gender – I don't think you're Albei or Pion. Especially not the latter, because otherwise, what's the point of your plan for tonight, and then put on a concert?
So, I don't see any peaceful roles for you.
