I had no reason to believe my kill on Fuji/Light would succeed, you know, given that I had already shot him and it failed.
I mean, I guess I could have taken his explanation about his kill immunity as a lie, but I more or less take that at face value when someone says that because there's a higher chance their just rewording what their actual ability is and covering their ass in case they're shot a buncha times. There's nothing to be gained if it just fails again. This is also why I chose to shoot Emi over him.
