Well, we can lynch Tris here.
If Odd is telling the truth, then Usopp was targeted with a kill and it hit someone else cause he was bus driven.
Tris never negated Usopp's action and instead either bus drove him or tried to kill him.
So that means Usopp shot Odd and for some reason the kill failed on Odd, or Usopp is just lying.
We can lynch Tris and get info on the players above ^
