Just connect the dots someone swaps ability's and someone dies in the same night. Also it's Kabutops I just realized I was saying kabuto... Kabuto needs something sharp to swap souls, which must means he kills whoever he swaps with.
I can't figure out exactly what it is you're assuming...
Swapping results in kill?
Sharp item equals death?
@Acetrainer_Samwise
Can you explain what you think happened in more detail? I'm also confused about your scattered mind comments, you claim that his role has changed, how do you know this if all you can do is swap abilities?
Can anyone here confirm that they were in possession of a sharp item?
