Mafia 101. Disputed Island

Nancy has an assault rifle, and Alex has a katana. Who do you think attacked with a psychic attack, causing the person to be afraid of the clanging of metal?

What role do you think Yashur plays?

Both of them could have done it, and both the rifle and the katana are made of metal.

I don't have much information on Yashur; Grandma knows better who he is. So, he could be either Ru or a newly recruited member.
